Semiconductor plants serve as the ultra-modern origins for every gadget we prize, and a crucial element of these ‘fabs’ is the cleanroom environment. Nevertheless, a TechTuber named Dr. Semiconductor has effectively established a ‘Class 100 cleanroom’ (ISO 5) inside his garden shed. Actually, he’s done quite a bit more than just make an empty cleanroom, with a set of interesting but compact chip tools already installed.
As the good doctor says, all the RAM, CPUs, and GPUs that PC enthusiasts covet rely on clean room facilities. Large tech firms like Intel, Samsung, and TSMC plan to allocate billions of dollars toward the development of their cleanroom sites. There, they will fabricate chips “inside cleanrooms thousands of times cleaner than a hospital operating room.”
This environment is essential, as a single speck of dust can ruin a whole chip or wafer. A speck of dust is like a boulder on a landscape built from the tiniest, intricate structures. Dust can also contaminate optics and other sensitive tools in the semiconductor process chain. Despite Elon Musk's claims, smoking cigars and eating burgers in a cleanroom would definitely be regarded as a lapse in decorum, if not worse.

Dr. Semiconductor started his shed makeover by weatherproofing the space. Multiple stages are shown for strengthening the building's inner framework. The enthusiast stresses that airflow and positive pressure are the true keys to an effective cleanroom. And the same positive-pressure methodology can help keep a PC's interior clean.
Once the TechTuber was satisfied with his sealing and filtration systems, he borrowed a particle counter. The instrument confirmed that he had achieved a Class 100 cleanroom standard in terms of particle count.
Upon stepping into the completed semiconductor shed, you first encounter a changing zone, which will be recognizable to anyone who has visited a business or collegiate site. Dr. Semiconductor’s tour shows that as we step into this area, there is a power management area which leverages grid and solar power, shelving with clean room suits, gloves, and chemical supplies.
Within the footage, after donning gear and entering the cleanroom, we receive a walkthrough from its originator. “It’s compact, but every inch is intentional,” remarks the skilled physician. “It has everything needed in order to make this a fully functioning semiconductor R&D space.”
Indeed, the tiny cleanroom isn’t just a sterile empty space; it contains some chipmaking tools. Dr. Semiconductor shows us his plasma etcher, vacuum furnace, and custom software-driven lithography machine to the left of the entrance. On the right side, there is a fume hood for chemical processing and spin coating (3D printed spin coater shown). A sample cleaner with a robot arm, some clear workspace, and a thin film deposition system are also present.
The video ends there, but Dr. Semiconductor suggests he is excited about disclosing information regarding the complete arrangement, “from the engineering tool sets, to the way everything functions, and all the wild creations that can be developed — ranging from circuits to sensors, to LEDs, and just so much more.”
Those particularly interested in hobbyist chipmaking might want to follow in Dr. Semi’s footsteps, or just see what is possible in a shed in 2026. In either case, it wouldn’t hurt to subscribe to the channel.
