OPEN SOURCE · NO FAB REQUIRED

Chips, made at home.

Open-source information for real semiconductor fabrication outside the multi-billion dollar fabs. Cleanrooms, lithography, deposition, etch, devices, and packaging, from the shed cleanroom behind the Dr.Semiconductor channel.

PROCESS MODULES

Guides

Each guide is a working process module, what it does, what it costs, where it bites, and how to build or run it yourself. More are added as the work happens.

Homebrew Chip Packaging
PACKAGING

Homebrew Chip Packaging

Getting a bare die wired to the outside world without a wire bonder — flip-chip bonding with plated indium on a standard PCB.

Making LEDs From an Epiwafer

The shortest path from a commercial InGaN epiwafer to your own blue light — minimal process, maximum electroluminescence.
WHY THIS EXISTS

About

Semiconductor fabrication is treated as something only billion-dollar fabs can do. It isn't. A Class 100 cleanroom fits in a garden shed, sub-micron lithography can run on a modified microscope, and working devices: LEDs, MOSFETs, DRAM, and more can be made at home. This site documents how, openly, so anyone can build on it.
