Process Engineer – Nanoimprint Lithography

Anlaseo Technology Ltd; Hong Kong; On-site; HKD 420,000 - 620,000; Full time

Job summary

Anlaseo Technology Ltd in Wan Chai, Hong Kong, seeks a Process Engineer specializing in nanoimprint lithography to develop and optimize micro/nanofabrication for microlenses and metalenses.

You will design UV and thermal imprint processes, advance photolithography, and perform DOE studies while collaborating with cross-functional teams to ensure end-to-end process compatibility in a fast-paced R&D environment.

Qualifications

• Bachelor’s degree or above in Microelectronics, Materials Physics, Optical Engineering, Micro/Nanofabrication or a related discipline.
• At least 3 years of relevant experience in semiconductor or optical micro/nanofabrication.
• Strong theoretical knowledge and hands-on proficiency in UV/thermal nanoimprint lithography, photolithography and thermal reflow.
• Familiarity with the full yellow-light process flow, including resist coating, exposure, development and etching.
• Proficiency in SEM, AFM and white-light interferometry.
• A solid foundation in micro/nano-optics; experience fabricating silicon-based lenses or diffractive optical elements is an advantage.
• Strong data-analysis skills and effective cross-functional communication and collaboration.
• Ability to work through multiple R&D iterations and proactively resolve technical challenges.

Responsibilities

• Develop and troubleshoot yellow-light cleanroom processes for microlenses and metalenses.
• Design and implement end-to-end UV and thermal nanoimprint lithography processes.
• Develop and optimize photolithography processes, including resist coating, exposure, development and baking.
• Develop wet processes and optimize parameters to achieve precise process-window control.
• Design and execute DOE studies to systematically validate imprint pressure, temperature and time, resist-thickness uniformity and overlay accuracy.
• Use SEM, AFM and white-light interferometry to identify defects and improve process yield.
• Write process SOPs and maintain process-parameter records and a troubleshooting knowledge base.
• Collaborate with upstream and downstream teams on etching, thin-film deposition and other process steps to ensure end-to-end compatibility.
