Ambitious semiconductor enthusiast builds DIY 'class 100 cleanroom' in his garden shed — contains a plasma etcher, vacuum furnace, and even custom software-driven lithography machine

A semiconductor enthusiast known as Dr. Semiconductor has built a 'Class 100 cleanroom' in his garden shed, complete with tools like a plasma etcher, vacuum furnace, and custom lithography machine. The cleanroom environment is crucial for chip fabrication, as even a speck of dust can ruin the process. Dr. Semiconductor meticulously sealed the shed, achieving the required particle count for a Class 100 standard. The compact cleanroom also features a fume hood, sample cleaner, and thin film deposition system, showcasing a full semiconductor R&D space. Dr. Semiconductor plans to share more details about his setup and the possibilities it offers for hobbyist chipmaking.
