Process Engineer / Postdoctoral Fellow in silicon microfabrication
The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore, about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether, PSI employs 2300 people.
The team headed by Prof. Stampanoni develops advanced imaging techniques at the synchrotron and in the lab and strives at the translation of novel imaging approaches to medical devices in a multidisciplinary effort involving academia, industry and medical partners.
We are looking for a highly motivated process engineer (or postdoctoral fellow) to engage in our grating fabrication project. You will contribute to the development of the microfabrication process of X-ray gratings in silicon substrate suitable for clinical testing in collaboration with our spin-off company GratXray. More specifically, you will be targeting the microfabrication of robust silicon gratings with pitch size in the micrometer range and aspect ratio higher than 70 by deep reactive ion etching (DRIE). This will include the deployment of novel fabrication protocols and challenging recipe optimization leveraging on our SPTS Rapier etcher.
For our ambitious project we are looking for a
Your tasks
- Pattern preparation of DRIE hard mask using UV lithography and plasma process
- Development of new recipes and recipe optimization (profile, aspect ratio for different feature sizes) of DRIE with SPTS tool for high aspect ratio gratings at 4-inch wafer scale
- DRIE process scaling up to 8-inch wafer scale
- Inspection with optical microscope, profilometry and SEM
- Internal data report and presentations
Your profile
We are a highly motivated and synergic team and we are passionate for challenging and non-conventional problem solving schemes. We are looking for a dynamic, hands-on person which thrives in a team environment. The successful candidate should have proven hands-on experience in clean room operation and silicon microfabrication, a master or PhD degree in Engineering, Physics, Chemistry, or Materials Science. Previous industrial experience is considered a plus. Prior experience with optical lithography, plasma physics and deep reactive ion etching (DRIE) is highly desirable. Good English and good communication skills are required.
We offer
Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure.
Your employment contract is limited to 2 years.
