Silicon Photonics Wafer Process Engineer

Moventas Wind Ltd; Espoo; Hybrid; EUR 65,000 - 90,000; Full time

Job summary

VTT invites applications for a Wafer Process Integrator to advance fabrication technology for photonic integrated circuits (PICs) in a state-of-the-art cleanroom environment in Espoo, Finland. You will work closely with PIC designers and process engineers to mature processes from concept to wafer-ready.

The role emphasizes hands-on process development, wafer-level quality control, and collaboration across disciplines to push silicon photonics forward in a global research setting.

Qualifications

• Master's degree in physics, photonics, chemistry, electrical engineering or related field with dedicated courses that cover semiconductor wafer processing technologies
• At least basic understanding of photonics, preferably including the theory and technology relating to optical waveguides, lasers and photodiodes
• At least basic understanding of microelectronics and semiconductor physics, including the theory and fabrication technology for devices like diodes, resistors and capacitors processed on semiconductor wafers
• Hands-on experience in semiconductor cleanroom processing, preferably for several years and preferably relating to some of the following fabrication technologies: Thin-film deposition technologies (LPCVD, PECVD, ALD, sputtering), Dry etching and plasma processing (RIE, ICP-RIE), Epitaxial growth (CVD, MBE), Process metrology (SEM, AFM, ellipsometry)
• Proficient in oral and written communication in English

Responsibilities

• Design and simulate fabrication process flows for PICs and optical waveguide components that are fabricated in Micronova on 200 mm wafers
• Prepare processing instructions for cleanroom operators, supervise their work in wafer processing and lead the implementation of fabrication runs
• Develop new and improved fabrication processes for PICs with main focus on passive SiN waveguide components and active Ge photodiodes
• Analyse and test the fabricated wafers, mainly on wafer-level, with primary focus on the quality and repeatability of the fabrication steps
• Interact with our PIC designers and PIC testing experts to ensure that the fabricated PICs meet our projects' and customers' needs
• Contribute to the reporting and dissemination of our research results
