Job description

Compound semiconductor process sustaining engineer has the primary responsibility of fabricating compound semiconductor lasers on InP wafers inside a cleanroom environment, ensuring that production line tools have maximized uptime, analyzing process data such as SPC charts, and addressing issues as first line of defense, and/or reporting issues to process/tool owner and cooperating with the team to resolve the issues. At times, the engineer may also need to participate in the improvement projects and new tool qualification (vendor contact, tool evaluation, installation, Factory Acceptance Test, qualification, etc.).

Job Duties

• Maintain various wafer process steps, including photolithography, wet and dry etching, PECVD, metal deposition, electrolytic plating, and chemical/mechanical polishing of compound semiconductor wafers.
• Establish or analyze Statistical Process Control (SPC) on a daily basis and report on any issues
• Review process yield and report on any yield loss, investigating the root cause
• Track tool performance/uptime metrics
• Generate/update Standard Operating Procedures, work order instructions, drawings, 5S documentation, and other production-line-related documentations.
• Promptly respond to the production line requests of wafer dispositions, maintain wafer flow, tracking daily schedule and report if there are any idle or deviations from the schedule, handle minor tool issues to resume production in a timely manner.
• Analyze and compile experimental data into reports for process improvement projects.
• Responsible for the basic maintenance and calibration of production machines, including mask aligner, hot plates, ovens, PECVD, ICP/RIE dry etchers, E-beam evaporators, thermal processing, microscopes, SEM, AFM, etc.
• Verify process conformance to the controls and specifications by utilizing inspection tools, such as optical microscopes, profilometers, ellipsometers, SEM, AFM, wafer inspection tools, etc..
• Perform other work-related tasks as required and assigned.

Qualifications

• Bachelor’s degree in Electrical Engineering, Material Science, Physics, Chemical, or related discipline is required
• 1 year experience in the laboratory environment is preferred
• 1+ years of experience in the compound semiconductor process is desired
• Knowledge and or hands-on experience of Six Sigma and/or SPC is a plus
• Robust critical analysis and problem-solving skills
• Detail-oriented; committed to quality and safety
• Self-sufficient learner, work well in the fast-paced work environment
• Comfortable to work under cleanroom hood and without any make-up
• Comfortable handling chemicals, including corrosive acids, bases, and solvents with Personal Protective Equipment
