Quick Summary

We're looking for a Process Engineering Intern to join our team in San Francisco, CA. As a Process Engineering Intern, you'll be responsible for designing and implementing process improvements, working closely with cross-functional teams to optimize the efficiency and effectiveness of our production processes. You'll have the opportunity to work on a cutting-edge semiconductor fab and contribute to the development of our team.

Job Description

About Atomic Semi

Atomic Semi is building a small, fast semiconductor fab.

It’s already possible to build this with today’s technology and a few simplifications. We’ll build the tools ourselves so we can quickly iterate and improve.

We’re building a small team of exceptional, hands-on engineers to make this happen. Mechanical, electrical, hardware, computer, and process. We’ll own the stack from atoms to architecture. Our team is optimistic about the future and we want to continue pushing the limits of technology.

Smaller is better. Faster is better. Building it ourselves is better.

We believe our team and lab can build anything. We’ve set up 3D printers, a wide array of microscopes, e-beam writers, general fabrication equipment - and whatever is missing, we’ll just invent along the way.

Atomic was founded by Sam Zeloof and Jim Keller. 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 role

We're hiring Process Engineering Interns for the fall term. The internship begins in September, with a preferred commitment of 4 to 8 months. We’re rebuilding the chip fabrication process from the ground-up, so you’ll be exposed to some really interesting and impactful work. This is a hands-on process engineering role—you’ll be responsible for experiment design and execution of new semiconductor 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.

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

• 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 deposition, etch, 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

• Pursuing a Bachelor’s Degree or higher in engineering

• Ability to learn quickly and troubleshoot technical problems

• Hands-on experience with wafer fabrication tools (etch, deposition, patterning) and metrology tools (AFM, SEM, thin film measurement, etc.)

• Recipe development and optimization for some subset of thin film deposition, dry etch, or lithography.

• Strong foundation in theoretical semiconductor knowledge (devices, fabrication, etc.)

Nice-to-have

• Familiarity with data processing in Python

• Mechanical or maintenance experience with fab tools
