The hidden workforce behind America’s semiconductor fab buildout

TL;DR

What workforce problem is being overlooked in the U.S. semiconductor expansion?
Fabs depend on a second-order semiconductor labor market outside their own payrolls: the engineers, chemists, operators, technicians, and specialists who produce and deliver semiconductor chemicals, gases, filtration, ultrapure water, CMP materials, and contamination-control systems.

How much semiconductor manufacturing investment is moving into the United States?
TSMC now lists $265 billion of planned Arizona investment, while Micron raised its planned U.S. fab and technology investment to more than $250 billion through 2035 in July 2026.

How dependent is semiconductor manufacturing on chemicals and materials?
Front-end semiconductor manufacturing uses more than 100 chemicals and materials. McKinsey estimates that roughly 60% of those material supply chains currently rely on imports.

How fast is semiconductor wet-chemical demand growing?
SEMI projects the market for major semiconductor wet-process chemicals to rise from about $3.8 billion in 2025 to $6.5 billion in 2030.

Is there really a U.S. semiconductor talent shortage?
Yes. SIA and Oxford Economics estimated that about 67,000 of roughly 115,000 new semiconductor jobs expected by 2030 could go unfilled at prevailing education and training rates.

Can semiconductor suppliers recruit from other industries?
Yes, for some roles. Pharmaceuticals, industrial gases, specialty chemicals, polymers, and other advanced manufacturing sectors can provide transferable skills, but employers need to identify which semiconductor-specific capabilities must already be present.

The semiconductor workforce is bigger than the people inside the fab

Most semiconductor workforce discussions start with the fab. That makes sense. The United States is building manufacturing capacity at a scale it has not attempted in decades.

TSMC’s Arizona plans have grown from an initial $12 billion commitment to $265 billion, covering six logic wafer fabs, two advanced packaging facilities, an R&D center, and supporting infrastructure. Micron increased its planned U.S. fab and technology spending to more than $250 billion through 2035.

The hiring impact extends well beyond those companies.

A modern fab depends on electronic gases, wet chemicals, photoresists, chemical mechanical planarization (CMP) materials, ultrapure water, filtration, chemical-distribution systems, high-purity piping, analytical laboratories, contamination-control technology, and the companies that manufacture, install, qualify, and maintain them.

McKinsey estimates that front-end semiconductor production requires a steady supply of more than 100 chemicals and materials. Its 2025 analysis found that roughly 60% of those material supply chains currently rely on imports, creating a substantial localization challenge as U.S. manufacturing capacity expands.

That creates a second-order semiconductor labor market. These engineers, scientists, technicians, operators, and specialists may never work for a chipmaker. The fab still depends on them.

Semiconductor chemical and gas suppliers are expanding with the fabs

The capital spending makes this second labor market easier to see.

In July 2026, Linde announced a $1 billion expansion of its Phoenix semiconductor gas complex. The company plans to add two air separation units to three already operating there, expanding its supply of ultra-high-purity nitrogen, oxygen, and argon for two additional fabs.

Air Liquide announced three major U.S. semiconductor investments during the same month:

  • More than $160 million for a new Arizona facility supplying ultra-high-purity gases.
  • More than $150 million for a new Idaho facility supplying ultra-pure nitrogen, oxygen, and argon to advanced memory production.
  • More than $170 million for two Indiana production units supporting SK hynix’s U.S. high-bandwidth memory (HBM) and advanced packaging operation.

The Arizona and Idaho facilities are scheduled to begin operations in 2028. Air Liquide expects to commission the Indiana units at the end of 2028.

Together with Linde’s project, those four announcements exceed $1.48 billion.

Every one of those facilities needs people before it can supply gas to a fab. The hiring requirements include process engineering, cryogenic systems, plant operations, controls and instrumentation, reliability, maintenance, process safety, commissioning, and operations leadership.

The semiconductor customer adds another layer: extremely tight requirements around purity, contamination, reliability, and qualification.

One fab creates jobs across several technical labor markets

The indirect workforce becomes easier to understand when the supply chain is translated into people.

  • Electronic and ultra-high-purity gases: Process engineers, cryogenic engineers, gas systems engineers, plant operators, reliability engineers, controls and instrumentation professionals, and process safety specialists.
  • Wet chemicals: Chemical engineers, purification specialists, production leaders, analytical chemists, quality professionals, process safety engineers, and maintenance teams.
  • CMP materials: Formulation scientists, colloid chemists, materials scientists, process engineers, and quality specialists.
  • Filtration and fluid handling: Polymer engineers, applications engineers, contamination specialists, and manufacturing engineers.
  • Analytical laboratories: ICP-MS chemists, trace-metal specialists, metrology professionals, and laboratory leaders.
  • High-purity installation: High-purity piping engineers, orbital welding specialists, construction quality professionals, and commissioning engineers.
  • Ultrapure water: Water-treatment engineers, facilities engineers, controls engineers, operators, and maintenance specialists.
  • Chemical and gas distribution: Facilities engineers, chemical systems engineers, gas systems engineers, EHS professionals, and commissioning teams.

SEMI’s standards library shows how specialized these environments become. Separate standards address high-purity polymers, ultrapure water, liquid chemical distribution, bulk chemical systems, chemical blending, high-purity piping, component particle contribution, and system qualification.

Calling all of this “semiconductor hiring” hides several different labor markets.

Wet chemicals are becoming a bigger semiconductor operating requirement

SEMI reported that global semiconductor materials revenue reached a record $73.2 billion in 2025, a 6.8% increase from 2024. Wafer fabrication materials accounted for $45.8 billion, and wet chemicals were among the categories posting strong double-digit growth.

SEMI’s August 2026 Bulk Wet Chemicals Report provides an even clearer signal. Demand for major wet-process chemicals used in semiconductor manufacturing is projected to rise from approximately $3.8 billion in 2025 to $6.5 billion in 2030.

More advanced manufacturing contributes to that growth. SEMI points to increasing numbers of cleaning steps, single-wafer processing, multi-step patterning, and reduced recycling rates as demand drivers.

Chemical consumption creates work across the entire path from production to point of use. Someone has to manufacture the chemical, purify it, test it, package it, transport it, distribute it inside the facility, qualify it, and investigate problems when specifications drift.

The workforce requirement grows with the complexity of the material system.

Purity changes what counts as relevant semiconductor experience

The term “parts per trillion” gets used frequently in semiconductor discussions, sometimes too broadly.

Semiconductor chemicals do not all operate under one universal purity specification. Requirements vary by chemistry, grade, manufacturing step, and contaminant.

The larger technical challenge is still extreme. Some semiconductor chemicals require ultra-high purity at parts-per-trillion levels, while specific materials can have their own requirements. McKinsey gives tungsten hexafluoride as one example, where six-nines purity, greater than 99.9999%, may be required.

Purity also involves more than the chemical leaving the manufacturing process.

The entire path can introduce contamination: tanks, piping, valves, pumps, filters, seals, packaging, cleaning procedures, installation work, maintenance, and the surrounding environment.

That changes the candidate profile.

A chemical engineer can understand fluid flow, reactions, heat transfer, plant operations, and process safety while having limited exposure to semiconductor contamination control.

A mechanical engineer can understand piping and equipment while having little experience with high-purity wetted surfaces, polymer extractables, electropolished systems, or semiconductor qualification.

An analytical chemist can understand ICP-MS while having limited experience connecting trace-metal results to semiconductor process specifications.

The underlying discipline transfers. The operating standard may still have to be learned.

High-purity semiconductor systems require specialized engineering skills

High-purity systems change what engineers need to know about materials.

SEMI F57 covers high-purity polymer materials and components used in ultrapure-water and liquid chemical distribution. Its requirements include metallic and ionic contribution, total organic carbon contribution, surface roughness, chemical resistance, reliability, traceability, packaging, and certification.

Other SEMI standards cover PFA testing, high-purity piping, bulk chemical distribution, system qualification, blending equipment, ultrapure-water systems, and particle contribution from components.

That can translate into recruiting indicators such as:

  • PFA and PTFE
  • Ultrapure water
  • Liquid chemical distribution systems
  • High-purity piping
  • Electropolished stainless steel
  • Orbital welding
  • Contamination control
  • Trace metals
  • Particle control
  • Chemical compatibility
  • Extractables
  • Clean manufacturing
  • System qualification

The job title will rarely tell you whether the candidate has those skills.

Analytical chemistry sits much closer to semiconductor production

Chemical quality in semiconductor manufacturing requires more than confirming the bulk composition of a material.

Laboratories may need to identify trace metals, ions, particles, moisture, organics, and other contaminants at extremely low concentrations. The analytical method depends on the chemistry and manufacturing requirement.

That creates demand for experience with technologies such as inductively coupled plasma mass spectrometry (ICP-MS), ion chromatography, mass spectrometry, particle measurement, and related analytical methods.

The recruiting implication is easy to miss. A semiconductor materials company can have a workforce problem that looks partly like chemical manufacturing, partly like laboratory science, and partly like semiconductor process engineering.

A search restricted to traditional semiconductor engineering titles can miss scientists and engineers working elsewhere in the supply chain.

Semiconductor filtration and fluid handling require their own talent

Entegris’ Colorado Springs investment illustrates how far the semiconductor supply chain reaches beyond gases and chemicals.

The Department of Commerce awarded the company up to $77 million in CHIPS funding toward a project with expected capital expenditure of about $722 million. The project supports production of front-opening unified pods (FOUPs), liquid filter membranes, advanced liquid filters, purifiers, and fluid-handling solutions.

Filters and fluid-handling components have a direct relationship with contamination control. The material carrying the chemical can become a contamination source itself.

That creates jobs in polymers, membrane technology, manufacturing engineering, quality, contamination control, applications engineering, process development, operations, and maintenance.

These roles are part of the semiconductor workforce even when the employer does not manufacture semiconductors.

Electronic materials are becoming a larger industrial category

Fujifilm’s acquisition of Entegris’ electronic chemicals business provides another example.

Fujifilm completed the $700 million transaction in October 2023. The acquisition added 593 employees and 12 sites, including seven manufacturing locations across the United States, Europe, and Singapore.

The acquired business added high-purity process chemicals used in wafer cleaning and etching to Fujifilm’s semiconductor-materials portfolio, which already included photoresists, photolithography materials, CMP slurry, post-CMP cleaners, and thin-film precursors.

The workforce implications reach far beyond electrical engineers, equipment engineers, and fab technicians. The semiconductor ecosystem also needs expertise in chemical manufacturing, materials science, formulation, analytical chemistry, quality, plant operations, safety, reliability, and maintenance.

The national semiconductor talent shortage number does not tell the whole story

The most established national semiconductor workforce estimate comes from the Semiconductor Industry Association and Oxford Economics.

Their 2023 study projected that the U.S. semiconductor workforce would grow from about 345,000 positions to approximately 460,000 by 2030, adding almost 115,000 jobs. Roughly 67,000 of those positions could go unfilled at prevailing education and training completion rates.

That 67,000 figure covers the semiconductor industry broadly. It does not provide a national shortage number specifically for semiconductor chemicals, gases, CMP, analytical chemistry, filtration, or ultrapure systems.

That distinction matters.

A company may need hundreds of technicians for a fab and one contamination-control leader for a supplier plant. The second position affects national semiconductor employment statistics far less, yet the employer may have a much smaller candidate pool.

Headcount and recruiting difficulty are different measurements.

Adjacent industries can expand the semiconductor talent pool

A more useful recruiting question is which parts of the role require semiconductor-specific judgment and which capabilities can transfer from another technical environment.

Several industries can produce relevant experience.

  • Pharmaceutical and biopharma manufacturing: Transferable experience can include sanitary process systems, clean utilities, validated cleaning, contamination control, high-purity water, regulated operations, and analytical chemistry.
  • Industrial gases: Transferable experience can include cryogenic systems, bulk gas production, hydrogen, gas purification, compressors, high-pressure systems, process safety, and plant operations.
  • Specialty chemicals: Transferable experience can include hazardous chemical production, purification, filtration, batch processing, chemical packaging, analytical testing, quality systems, and process safety.
  • Specialty polymers: Transferable experience can include fluoropolymers, resin chemistry, extrusion, chemical compatibility, high-purity components, and controlled manufacturing.

Gaps differ for every candidate. Candidates may still need to learn semiconductor contamination requirements, SEMI standards, fab qualification, customer specifications, and semiconductor process knowledge.

Employers need to decide which gaps they can train around and which ones create too much risk for the particular position.

Semiconductor hiring competition is becoming regional

The geographic pattern adds another recruiting challenge.

In Phoenix, TSMC is expanding while Linde and Air Liquide are adding gas capacity. In Idaho, Micron’s expansion is bringing additional industrial-gas infrastructure. In Indiana, SK hynix’s HBM investment is creating demand for supporting gas production. Colorado Springs has Entegris building filtration and fluid-handling capacity.

A controls engineer might fit the fab, gas plant, chemical supplier, equipment manufacturer, or another advanced manufacturer in the region.

The same can be true for process engineers, reliability professionals, maintenance leaders, EHS specialists, and commissioning engineers.

Semiconductor employers also compete with aerospace, automotive, energy, pharmaceutical, medical technology, chemical, and other advanced manufacturing employers for many of these workers.

The result is a labor market where company boundaries matter less than technical capabilities.

Semiconductor recruiting needs to look beyond job titles

“Process Engineer” can describe hundreds of fundamentally different jobs.

So can “Chemical Engineer,” “Facilities Engineer,” “Quality Manager,” and “Operations Manager.”

A semiconductor supplier search becomes much more precise when it starts with the actual technical environment.

Depending on the position, useful indicators can include:

  • Semiconductor chemicals
  • Electronic materials
  • Electronic specialty gases
  • Ultra-high-purity systems
  • PFA and PTFE
  • High-purity piping
  • Ultrapure water
  • ICP-MS
  • Trace metals
  • Particle control
  • CMP
  • Slurry formulation
  • Photoresists
  • Wet chemistry
  • Gas distribution systems
  • Toxic or pyrophoric gases
  • HAZOP
  • Process safety management
  • Clean manufacturing
  • Commissioning
  • Customer qualification

The resume then needs to answer a more important question: What did the candidate actually design, manufacture, operate, analyze, qualify, troubleshoot, or own?

That is where a candidate from an unexpected industry can become more relevant than someone carrying the expected job title.

Semiconductor reshoring is creating a second-order labor market

The U.S. semiconductor workforce discussion usually counts employment at chipmakers and the large number of construction and technical jobs associated with new fabs.

The supplier workforce deserves its own attention.

A fab requires a continuous flow of qualified gases, chemicals, materials, water, filtration, parts, and technical services. Those suppliers need people who can manufacture those products to semiconductor standards and keep the systems running after production starts.

This labor market will not always show up cleanly in semiconductor employment statistics. Some of these workers will sit inside chemical companies, industrial-gas companies, materials manufacturers, filtration companies, engineering firms, laboratories, utilities contractors, and equipment suppliers.

They still affect how much semiconductor manufacturing capacity the United States can operate.

For employers building or expanding this part of the semiconductor supply chain, STEM Search Group recruits across engineering, manufacturing, materials and chemical, scientific, AI and technology, and other specialized technical markets. That overlap matters because the right candidate may already work in semiconductors, or that person may sit one industry away with most of the difficult experience already in place. Finding the difference requires understanding the work behind the title.
