Optical Coating Engineer

Applied Optoelectronics, Inc. is currently seeking a highly motivated and experienced person to operate optical coating equipment for fabrication of thin film semiconductors.

include operation, maintenance, modifications, designs and repairs to the coating equipment.

• Responsible for optical coatings based on ion beam assisted sputtering and e-beam evaporation
• Monitor coating deposition and take necessary actions during the run
• Check daily coating results and fine tune the equipment setting for next run by optimizing process parameters - e.g., Gas flow, substrate temperature, rate of deposition to achieve desirable properties of films.
• Maintain production coating runs for high quality AR and HR coatings on facets
• Solve issues - e.g., Leak in chamber, dry pump, cryo pump maintenance, dealing with vendors to buy parts.
• Optical measurements on ellipsometry for various coating characteristics.
• Lead maintenance, modifications, repair of coating machines
• Equipment modification to improve throughput or stability
• New coating design for new applications
• Written and oral reports and SOPs.
• Train and support production line

• Education: Master in Electrical Engineering, Physics, or semiconductor related field, specialty in thin film deposition is a plus
• Experience: Minimum one year experience on e-beam coating and Ion beam sputtering coating.
• Hands-on optical coating process knowledge
• Knowledge and hands on skills of high vacuum techniques and equipment
• Well-developed interpersonal and communication skills.
