What Does a Semiconductor Technician Do?
Semiconductor technicians load silicon wafers into furnaces, etchers and deposition tools, set each run to its approved recipe of times, gases and temperatures, then inspect the results for scratches and pattern defects. All of it happens in full gown, inside the cleanrooms of chip plants and university fabrication labs. Their charts usually catch a drifting process first.

Semiconductor Technician Duties and Responsibilities
The primary responsibilities of a semiconductor technician include:
- Load wafers into furnaces, etchers and deposition tools and run approved process recipes.
- Gown up and follow cleanroom protocols to keep particles off wafers and tools.
- Measure film thickness and line widths with ellipsometers, profilometers and microscopes.
- Inspect wafers for scratches, particles and pattern defects, and flag lots that fail.
- Coat, expose and develop photoresist on spin coaters and mask aligners.
- Log each run, reading and tool alarm in the lot tracking system.
- Handle acids, solvents and hydrofluoric acid under strict chemical safety rules.
- Perform preventive maintenance on vacuum pumps, chambers and wet benches.
- Plot measurements on control charts and alert engineers when a process drifts.
- Train students and new staff on tool use in a university nanofabrication lab.
Required Skills and Qualifications
To succeed as a semiconductor technician, you will need the following skills and qualifications:
- Cleanroom gowning and contamination control
- Photolithography, etch and deposition tools
- Metrology tools such as ellipsometers and profilometers
- Statistical process control charts
- Chemical safety, including hydrofluoric acid handling
- Vacuum systems basics
- Careful, by-the-book work habits
- Good near vision and steady hands
Education and Training
Entry to a fab with only a high school diploma might be possible, but applicants with an associate degree in electronics or semiconductor technology will have a clear lead over other candidates. Experience of cleanroom work could lead to a senior technician post. Most fabs require technicians to be on rotating shifts.
Salary and Job Outlook
Typical pay: $45,640 - $65,010 per year, with a median of $51,430.

BLS projects employment of semiconductor processing technicians to grow about 8 percent from 2025 to 2035, with roughly 3,400 openings a year. Demand will rise for several reasons, including new chip plants under construction in the US; more chips in everyday goods, such as cars and appliances; and research, as labs develop new devices.
