Semiconductor Metrology & Quality Control Technician

About the role

As part of the Operations team, you will be day-to-day responsible for metrology and quality control, as well as die sorting and packaging, in a semiconductor cleanroom. You will characterize wafers and chips with metrology tools, run incoming and outgoing inspections, operate the pick-and-place machine for die sorting and packaging, and document products with full traceability. You will work closely with process, design and test engineers, as well as fab partners and suppliers.

Key responsibilities

• Metrology: perform wafer- and chip-level measurements with SEM, stylus profilometer, optical and confocal microscopes and ellipsometer (film thickness, critical dimensions, etch depth, step height, surface topography and defects); set up and maintain measurement recipes, keep tools calibrated and coordinate with service providers.
• Sorting and packaging: sort chips and dies by hand with manual and vacuum tweezers, operate the pick-and-place machine to move dies from singulated wafers on tape to shipping containers such as GelPak, waffle pack and JEDEC trays, and handle wafer taping, die marking, final sorting, packaging and sealing in vacuum bags.
• Data and reporting: record, analyze and report measurement results in a traceable way, flag out-of-spec results, support root-cause investigations and trend key parameters.
• Incoming quality control: inspect incoming wafers, chips and materials against specifications, complete goods acceptance documentation and handle nonconforming material.
• Outgoing quality control: perform final visual and dimensional inspection, prepare Certificates of Conformance and inspection reports, and ensure packaging meets quality standards.
• Traceability: label and identify every wafer and chip, keep inventory and traceability records accurate in the ERP and PLM systems, and share standards across R&D and production.
• Procedures and improvement: contribute to work instructions and inspection procedures, and suggest practical improvements, including automation ideas for engineers and the MES system.

Required profile

• 5+ years of hands-on metrology and quality control experience in semiconductor, photonics, MEMS or a related micro- and nanofabrication environment (e.g. watch industry, medical instruments).
• Technical education such as an EFZ apprenticeship (e.g. Mikrotechnologe/in, Physiklaborant/in), a higher technical diploma or an FH degree in a related field.
• Proven experience in ISO 5 / ISO 6 cleanrooms and gray rooms, with tool maintenance and calibration.
• Meticulous, reliable and hardworking, with a quality mindset; familiarity with quality standards (e.g. ISO 9001) and nonconformance handling; experience preparing CoCs or inspection reports is a plus.
• Good English preferred; German, French or Italian is a plus.

Required skills

• Hands-on operation of SEM, profilometry, optical and confocal microscopy, ellipsometry and pick-and-place machines.
• Dexterity with manual handling of wafers and chips with tweezers.
• Comfortable with Microsoft 365, especially Excel for data analysis.
• Experience with ERP and PLM systems, and with automation and MES, is a plus.

What we offer

• A competitive compensation and benefits package, including an employee stock option plan (ESOP).
• The chance to shape metrology and quality control in a photonics company serving the AI datacenter market.
• The opportunity to grow professionally at a fast pace in an early-stage startup.
