Wafer Process Engineer

We are seeking a semiconductor process engineer.

The engineer will primarily be responsible for 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 when necessary.

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.).

• Develop and or 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), process yield, and measure tool performance/uptime metrics.
• Generate Standard Operating Procedures, work order instructions, drawings, 5S documentation, and other production-line-related documentations.
• Promptly respond to the production line requests of wafer disposition, maintain wafer flow, handle 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.

• Bachelor’s degree in Chemical, Electrical Engineering, Material Science, Physics, or related discipline is required
• Minimum 1-year experience in the laboratory environment is required
