Principal Process Engineer

Take lead on various engineering efforts in an advanced InP BH laser fab, including process development, yield improvement, trouble shooting, tool qualification, etc.

Responsibilities:

• Design and DOE to develop processes (photolithography, chemical etch, film deposition) for new products. Define process specification and qualify the process for production.
• Develop metrology methods to characterize and monitor processes. Continuously improve existing processes to reduce fluctuation and improve process yield.
• Work with product engineers to correlate process data with final product yield. Identify critical steps and conduct continuous improvement to improve product yield.
• Troubleshoot any issues occurring in production. Investigate root cause and develop solutions.
• Work with equipment team and help maintain process equipment. Participate in new equipment selection. Lead the process development and qualification on new equipment.

Requirements:

• MS or PhD (preferred) in electrical engineering, material, chemistry, or mechanical engineering.
• More than 8 years’ experience working in semiconductor fab
• Comprehensive understanding on process and metrology technologies, including photolithography, chemical etch, film deposition, SEM, EDS, etc.
• Demonstrated good records of process development and maintenance.
• Has experience to define and prepare work instructions.
• Excellent communication skills, able to mentor junior engineers and train technicians.
