Semiconductor Process Technician

Semiconductor Process Technician

(Lapping and Polishing)

Location: San Jose, Ca.
Schedule: 2nd shift (12pm-8pm)

Type: Temp to Permanent

Compensation: $25-$28/hr. or higher based on experience

About the Company

An established precision manufacturing company is seeking several Lapping and Polishing Technician to support their production team. The company processes components for demanding technical applications, helping customers achieve specific requirements for dimensions, thickness, flatness, and surface quality.

The work involves a range of materials, including metals, glass, ceramics, and semiconductor substrates. Projects require careful handling, consistent processing, and accurate inspection to ensure finished components meet customer specifications.

About the Position

The technician will operate equipment that removes small, controlled amounts of material from precision semiconductor parts. Lapping helps establish the required dimensions and flatness, while polishing further refines the surface to reduce scratches and roughness.

This position combines machine operation, equipment setup, part handling, and in-process inspection. Direct lapping or polishing experience is valuable, and the company is also open to training candidates with relevant hands-on manufacturing skills.

Responsibilities

• Set up and operate lapping and polishing equipment according to work instructions.
• Prepare fixtures and load and unload components carefully.
• Select and use appropriate abrasives and processing supplies within established guidelines.
• Monitor parts throughout the process and adjust operating parameters as needed.
• Verify dimensions and part quality using micrometers, calipers, indicators, and other inspection tools.
• Read and follow technical drawings, specifications, and production instructions.
• Inspect components for scratches, surface defects, dimensional variation, and other quality concerns.
• Record production information, measurements, and inspection results.
• Communicate process issues to supervisors and quality personnel.
• Support routine equipment care and preventive maintenance.
• Follow safety procedures and maintain a clean, organized work area.

Relevant Backgrounds

Candidates may bring direct lapping and polishing experience or transferable skills from:

• Precision grinding or surface grinding.
• Optical fabrication or glass finishing.
• Ceramic machining or materials processing.
• Semiconductor manufacturing or wafer processing.
• Metallographic or laboratory sample preparation.
• CNC machining or precision machine operation.
• Manufacturing work involving delicate components, measuring tools, and close tolerances.

Qualifications

• Hands-on manufacturing or equipment-operation experience is helpful.
• Ability to follow detailed instructions and maintain consistent results.
• Familiarity with measuring tools such as micrometers, calipers, or indicators is preferred.
• Ability to read technical drawings and specifications, or a willingness to develop those skills.
• Strong attention to detail and manual dexterity.
• Basic math and problem-solving skills.
• Ability to document results and communicate concerns clearly.
• Reliable attendance and availability for a full-time, on-site afternoon/evening schedule.
• High school diploma or equivalent; technical coursework or manufacturing training is a plus.
