Job description
Primary Duties & Responsibilities
- Develop and optimize wet etch processes for VCSELs, photodiodes, and edge-emitting lasers on GaAs and InP substrates.
- Define and control etch chemistry, etch rate, isotropic vs. anisotropic etching, selectivity, and undercut management to meet stringent device performance criteria.
- Utilize metrology tools such as AFM, SEM, ellipsometry, profilometry, XPS, XRD, and optical interferometry for process characterization and defect analysis.
- Troubleshoot etch process deviations, material compatibility issues, and surface roughness effects, implementing corrective actions to ensure high device yield and process stability.
- Work closely with device engineers and integration teams to integrate wet etch processes into the overall semiconductor fabrication flow.
- Establish and maintain SPC methodologies for process monitoring and continuous improvement.
- Evaluate and qualify new wet etch chemistries, process automation techniques, and etch equipment to enhance process capabilities.
- Develop and document etch process recipes, SOPs, failure analysis reports, and best practices for knowledge sharing and training.
- Mentor junior engineers and provide technical leadership in wet etch process development for optoelectronic applications.
Education & Experience
- Bachelor's, Master's, or Ph.D. in Materials Science, Electrical Engineering, Chemical Engineering, Physics, or a related field.
- 10+ years of hands-on experience in semiconductor wet etch process development, particularly for GaAs and InP-based optoelectronic devices.
- Strong expertise in wet etch chemistry, selectivity optimization, surface roughness control, and etch stop layers.
- Hands-on experience with metrology techniques such as SEM, AFM, ellipsometry, profilometry, XPS, and XRD for process verification and defect analysis.
- Deep understanding of etching challenges for VCSELs, photodiodes, and EMLs, including precise mesa formation, sidewall passivation, and optical performance impact.
- Proficiency in SPC, DOE, and data-driven process optimization.
- Ability to work in a cleanroom environment and collaborate with cross-functional teams, including device engineers, production teams, and R&D groups.
Skills
- Experience in high-volume semiconductor manufacturing or advanced R&D prototyping for optoelectronic devices.
- Familiarity with chemical safety, fume hood operations, and waste disposal protocols for semiconductor wet etch processing.
- Familiarity with automation (SECS/GEM), scripting, or AI-driven process control, including FDC and APC.
- Demonstrated leadership in technical project management, process transfers, and mentoring junior engineers.
Working Conditions
- Will be exposed to areas where hand tools and power tools are being operated
- Will be exposed to areas where hazardous chemicals or gases are stored
- Ability to work in a cleanroom environment per semi-conductor protocol/requirements
Physical Requirements
