Job summary

Anlaseo Technology Ltd in Hong Kong is seeking a Process Engineer to develop and optimize etching processes for photonic and semiconductor materials, supporting stable transfer, equipment capability and new-product introduction.

You will work with ICP/RIE dry-etch and wet-etch processes, tune gas chemistry, RF power and pressure, and use SEM/AFM and other tools to analyze sidewall morphology and ensure process quality.

Qualifications

• Bachelor-level degree in microelectronics, physics, materials science, or related field.
• Hands-on dry-etch experience with GaAs, InP, Si or related compounds.
• Proficient with ICP/RIE equipment (Oxford, LAM, STS, NAURA or equivalents).
• Strong knowledge of plasma physics and III-V etching characteristics.
• Experience with DOE and data analysis tools (JMP, Minitab).
• Familiar with SEM, AFM, profilometers, ellipsometers; cleanroom capable.
• Willing to travel or be assigned to external worksites.

Responsibilities

• Develop and troubleshoot ICP/RIE dry-etch processes for InP, Si and related materials.
• Develop wet-etch processes with precise etch rate and undercut control.
• Optimize gas chemistry, RF power, pressure to balance etch rate and selectivity.
• Use SEM and other tools to assess sidewall morphology and ratio.
• Prepare etching SOPs, work instructions, and inspection reports.
• Collaborate with R&D for process improvements and NPI.

Job description

Process Engineer

About the Role

Develop and optimize dry and wet etching processes for photonic and semiconductor materials, supporting stable process transfer, equipment capability and new-product introduction.

Key Responsibilities

• Develop and troubleshoot ICP/RIE dry-etch processes for InP, Si and related materials.
• Develop wet-etch processes for specified materials, with precise control of etch rate and lateral undercut.
• Optimize gas chemistry, RF power, chamber pressure and other process parameters to maintain etch rate, selectivity and sidewall-profile stability.
• Use SEM and other characterization tools to measure and analyze sidewall morphology, aspect ratio and selectivity after etching.
• Resolve process-related product anomalies; monitor equipment capability and support routine tool maintenance.
• Prepare etching SOPs, work instructions and inspection reports.
• Partner with R&D teams on process improvements and participate in new product introduction (NPI).

Requirements

• Bachelor’s degree or above in Microelectronics, Semiconductor Physics, Materials Science, Optoelectronics, Condensed Matter Physics or a related discipline.
• Hands‑on dry‑etch experience with GaAs, InP, Si or related compound-semiconductor materials.
• Proficient in mainstream ICP/RIE equipment, such as Oxford, LAM, STS, NAURA or equivalent.
• Strong understanding of plasma physics, surface-chemistry reaction mechanisms and III-V material etching characteristics.
• Proficient in design of experiments (DOE) and data analysis using JMP, Minitab or equivalent tools.
• Familiar with SEM, AFM, profilometers, ellipsometers and other characterization methods.
• Able to work in a cleanroom environment with rigorous working practices and strong safety awareness.
• Willing to travel or be assigned to external worksites when required.

Location and Work Arrangement

Based in Hong Kong, with assignment to external worksites when required.

Benefits

• Monthly salary of HK$25,000–35,000 depending on experience, with year-end bonus.
• MPF, supplementary commercial insurance and regular health check-ups.
• Five‑day work week, paid annual leave, holiday benefits and team‑building activities.
• Equity incentive plan for core roles at a startup.
