Full Job Description

Location: Alhambra, CA (Onsite)

Position Summary: The Process Development Engineer – InP Wafer Fab position is responsible for development, optimization, and manufacturing support of deposition and etch process modules used in the fabrication of Indium Phosphide ( InP )–based photonic devices, including DFB lasers, Semiconductor Optical Amplifiers (SOAs), and Gain Chip (GC) products. This role provides technical ownership of PECVD deposition processes and dry/wet etch technologies, serving as the primary process expert for dielectric films and plasma etch systems within the wafer fabrication facility. The position focuses on profile control, uniformity, yield improvement, manufacturing stability, and tool performance to enable robust and scalable production.

Responsibilities :

Deposition and Etch Process Development & Ownership (35%) :

Develop, qualify, and maintain PECVD dielectric deposition processes for InP -based device structures

Develop and optimize dry etch (ICP-RIE/RIE) and wet etch processes for InP and related material systems

Own PECVD and ICP-RIE/RIE tools, including recipe control, chamber conditioning, and process stability

Define and maintain process windows, control limits, and equipment qualification requirements

Tool Ownership, Control, and Manufacturing Stability (25% ) :

Coordinate preventive maintenance and tool performance monitoring

Drive process uniformity, film thickness control, etch profile control, and critical dimension (CD) performance

Monitor tool health and respond to excursions impacting yield or reliability

Support capacity scaling, equipment qualifications, and tool transfers

Failure Analysis and Root-Cause Resolution (20%) :

Lead and coordinate failure analysis (FA) activities using structured problem-solving methodologies (e.g., 8D, Six Sigma)

Identify defect mechanisms and process-induced failure modes through cross-functional investigation

Leverage FA techniques such as optical inspection, SEM, FIB, SIMS, and electrical analysis (directly or via partners)

Ensure corrective and preventive actions are implemented and verified for effectiveness

Yield Improvement, Excursion Response, and Root-Cause Analysis (20%) :

Lead defect reduction and yield improvement initiatives related to deposition and etch processes

Perform structured root-cause investigations using data analysis, DOE, and failure analysis inputs

Analyze inline and electrical test data to identify trends, drifts, and emerging risks

Implement corrective and preventive actions and verify long-term effectiveness

New Product Introduction and Technology Support (10%) :

Support new product introduction (NPI), process transfers, and technology scaling efforts

Evaluate process risks associated with new materials, designs, and device structures

Interface with photo, metallization, device, and manufacturing teams to resolve integration issues

Documentation, Process Control, and Manufacturing Support (10%)

Author and maintain SOPs, process specifications, travelers, and control plans

Define and maintain SPC metrics and control strategies for deposition and etch processes

Provide hands-on manufacturing and on-call support as required

Minimum Qualifications :

Bachelor’s degree or higher in Chemical Engineering, Materials Science, Electrical Engineering, Physics, or a related field

Minimum of 3+ years of experience in semiconductor deposition and/or etch process engineering

Hands-on experience with PECVD systems and ICP-RIE/RIE etch tools

Strong hands-on understanding of InP -based or III-V compound semiconductor wafer fabrication processes

Strong understanding of plasma processes, etch chemistries, and thin-film properties

Demonstrated experience with profile control, uniformity improvement, and SPC

Strong data analysis and problem-solving skills

Ability to drive technical ownership in a manufacturing environment

Preferred experience with InP or III-V compound semiconductor devices

Familiarity with DFB lasers, SOAs, gain chips, or photonic device manufacturing preferred

Experience supporting high-mix, low-volume manufacturing environments preferred
