Job Description:
The position is to be an integral part of a wafer fab manufacturing engineering team for the fabrication of III-V compound semiconductor-based optics/optoelectronic components, covering laser diode (tunable semiconductor laser, distributed feedback laser-DFB, modulated single-frequency laser), photodetector, modulator, integrated photonics, and glass-based optical passive diffractive elements in high volume manufacturing. The candidate will interface closely with manufacturing production as well as various product engineers, equipment engineers, and process engineers, to both maintain and improve legacy wafer fab chip products and to develop new products.

In this position you will:
Oversee, sustain, ramp-up and develop a diverse range of state-of-the-art wafer fabrication and characterization/metrology processes for submicron grating manufacturing.

Design, build, setup, and improve custom tools based on optical table setups, involving mechanical, optical, and control automation programming aspects.

Engage with contract manufacturers regarding processing services.

Evaluate, develop, establish, automate and maintain various optical characterization systems for new product characterization and for wafer fab manufacturing.

Utilize wafer fab metrology infrastructures in order to meet all key production matrices including the line yield, wafer cost/cycle time, commitment delivery, lean manufacturing, engineering change orders, statistical process control/analysis/reports, work instructions, corrective actions, high-level production, training, manufacturing execution system (MES), process flow, volume manufacturing, gage R&R, calibration, and other manufacturing documentation/logistics.

Analyze, prioritize and high-level debug root-cause problems of escalated fab processing and characterization issues throughout the entire life cycle of chip products and perform failure analysis.

Provide technical support to production and equipment maintenance teams to resolve problems and keep metrology tools running well. Provide data analysis and assist epitaxy and process engineering team members to develop, optimize, and troubleshoot their processes.

The successful candidate will have a MS degree in materials science, electrical engineering, optics, solid-state physics or equivalent and 3+ years of applicable hands on experience or a PhD in electrical engineering, optics, solid-state physics or equivalent.

5 years’ experience with wafer fab processing, especially with III-V compound based grating process patterning and its characterization, including familiarity with optical holography, electron-beam writing, or other submicron fabrication technologies.

Deep familiarity and hands-on experience with optical and mechanical system design, setup, automation and system improvements for wafer level characterization.

Solid experience with Excel VBA macros, LabVIEW, and either C++, Visual Basic, or Matlab are required.

Ability to work independently and on teams in a deadline driven, production environment.

Must have strong problem solving and communications skills, and be team player.

Willingness to work during swing shifts (afternoon to evening) in order to support 24×7 fab manufacturing and additional off-hours for on-call support is required.

SPC, and JMP or Minitab or equivalent. Experience with design of experiments and statistical process control (SPC) is preferred.

Experience in optical thin film, optical characterization setup is a plus.
