We are building Atomic Studio to match the speed of our fab. It’s fast, browser-based, and collaborative. Layout, schematic, and simulation. Here’s a side by side of Studio (left) and Klayout (right) moving through the same file.

We talked to a few hundred students at Waterloo and CMU this week about building small, fast semiconductor fabs. Interns build the hardware and software tools in our fab. You get a credit card, space in our lab, machine shop access, and great mentors. The rest is up to you.
