AMS is a global leader in the design and manufacture of advanced sensor solutions.
Based on our state-of-the art Vertical Cavity Surface Emitting Laser (VCSEL) technology and our optical design and packaging capabilities, we provide unique solutions for all 3D sensing cameras.
The solutions are used in a variety of consumer electronic platforms such as face recognition applications for mobile devices, gesture and people recognition for home systems, robotics navigation, and Advanced Driver-Assistance Systems (ADAS) for automotive.

Our VCSEL R&D team is seeking an experienced process development engineer to contribute to the development of our next generation high efficient VCSEL chips, and to combine micro-optics to the laser systems at wafer level to develop advanced optical components and subsystems for high volume applications.

Job Responsibility:

· Develop, qualify and implement VCSEL fabrication process for new product development.

· Define process design rules, mask layout, metrology method and process specifications

· Design, carry out, and refine DOEs of process recipe development in clean room

· Monitor engineering process lots through fabrication and analyze metrology data.

· Perform statistical process control method to monitor process for trouble shooting and

process optimization

· Automate, qualify and document new process for mass production.

· Support manufacturing team to improve process quality and process yield.

· Study and qualify new equipment as necessary for new process module.

· Involve in project improvement, program meetings or design review meetings as necessary.


· Ph.D.
in Electrical Engineering, Physics, Material Science, Chemistry or equivalent with

minimum 5 years of hands on experience in wafer fabrication process development.

· Demonstrate experienced skills in semiconductor process such as photolithography (contact

alignment, stepper, e-beam lithography, etc.), wet and dry etch (RIE, ICP) processes, thin film

deposition (e-beam evaporation, sputter deposition, PECVD, electroplating, etc.), and

metrology (profilometry, reflectance spectroscopy, AFM, SEM/EDX, etc.),

· Strong knowledge and mindset in SPC, control plan, DOEs and quality.

· Strong skills in data analysis (JMP, minitab, matlab, python, etc.)

· Self-motivated, detail oriented, and good team work attitude.

· Good written and communication skills

· Experience with VCSEL process is a plus

· Knowledge in laser device test is a plus
