About fab2 The fab2 team can build anything. We design all the hardware and software needed to make chips and we make the fabs, tools, and components ourselves. We're looking for exceptional, hands-on people who can iterate to the limits of what's possible. fab2 was founded by Sam Zeloof https://www.youtube.com/@SamZeloof and Jim Keller https://en.wikipedia.org/wiki/Jim_Keller_(engineer). Sam is best known for making chips in his garage, and Jim has been a leader in the semiconductor industry for the past 40 years. About the team The Process Team sits at the heart of our in-house device development, driving the design of each new generation of tools. This is unlike any role at a traditional foundry—we simultaneously develop recipes, apply novel materials, test and characterize our chips, and troubleshoot tools. About the role As a Process Development Engineer, Etch at fab2, you’ll be responsible for experiment design and execution of new semiconductor, etching and thin-film fabrication methods. We're looking for someone with both a strong understanding of traditional semiconductor processing methods and an open-mindedness to new techniques. It'll be helpful if you have the ability to digest and filter a large body of existing work (academic papers, books, etc.) This is a high-ownership role with lots of autonomy in a fast-moving startup environment. You’ll have the opportunity to contribute to novel R&D processes and influence tool design. Candidates should have hands-on cleanroom experience and a track record of developing nanofabrication recipes from scratch, ideally across multiple process steps. Responsibilities - Work in the lab to design and run experiments alongside senior process engineers - Read academic papers and technical literature to inform experimental design; whiteboard ideas and iterate quickly - Learn and operate a range of semiconductor tools, including etch, deposition, lithography, and metrology systems - Develop, transfer, and optimize process recipes across platforms with a focus on consistency, yield, and throughput - Analyze process data, troubleshoot recipe or equipment issues, and clearly document findings and results for the team Required Experience - BS, MS or PhD in Electrical Engineering, Materials Science, Chemical Engineering or related field - Hands-on cleanroom experience with multi-step fabrication flows - Experience operating dry etch, thin film deposition, and lithography tools - Recipe development and optimization for some subset of dry etch, thin film deposition, or lithography - Familiarity with key metrology such as ellipsometry, profilometry, SEM, etc Nice-to-have - Mechanical or maintenance experience with fab tools - Full device‐flow experience Working at fab2 We’re an early-stage hardware startup with solid funding, world-class advisors, and labs/offices in Austin, TX, Lockhart, TX, and San Francisco, CA.
