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

As a Process Integration Engineer at Atomic Semi, you will play a pivotal role in designing and integrating novel process flows. You’ll also collaborate with engineers to design in-house fabrication equipment. The ideal candidate will bring a strong understanding of traditional semiconductor processing methods as well as 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).

Hands-on experience with traditional CMOS devices is required (e.g. at a foundry or in research).

Responsibilities

  • Build in-house CMOS fabrication process flows.

  • Incorporate novel processes into existing CMOS flows and ensure compatibility.

  • Ability to digest and document full process flows.

  • Utilize in-depth knowledge of Silicon CMOS process flow to design and implement robust semiconductor fabrication processes.

  • Apply nanofabrication techniques to develop cutting-edge devices.

  • Collaborate with cross-functional engineering teams to develop and optimize in-house semiconductor fabrication equipment.

Required Experience

  • Degree in Electrical Engineering, Physics, or a related field.

  • Strong understanding of Silicon CMOS process flow.

  • Hands-on experience fabricating transistors.

  • Strong device physics background.

  • Analytical mindset and problem-solving skills.

  • Effective communication and collaboration skills.

Nice-to-have

  • Experience in transistor simulation.

  • Familiarity with typical semiconductor characterization methods and tools.

  • Familiar with CMOS layout or VLSI.
