About the role
- 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
- 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
- Drive process uniformity, film thickness control, etch profile control, and critical dimension (CD) performance
- Support capacity scaling, equipment qualifications, and tool transfers
- Lead and coordinate failure analysis (FA) activities using structured problem-solving methodologies (e.g., 8D, Six Sigma)
- Leverage FA techniques such as optical inspection, SEM, FIB, SIMS, and electrical analysis (directly or via partners)
- 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
Requirements
- 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 understanding of plasma processes, etch chemistries, and thin-film
- Demonstrated experience with profile control, uniformity improvement, and SPC
- Incumbents may be required to perform job-related tasks other than those specifically included in this description.
- Provide hands-on manufacturing and on-call support as required
Nice to have
- 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
Compensation
- A reasonable estimate of the pay range for this position is $73,000 - $110,000.
Benefits
- Monitor tool health and respond to excursions impacting yield or reliability
