The project resulted in a 5×4 DRAM cell array, fabricated in a shed-based clean room using spin-on-glass doping instead of industry-standard ion implantation.
Although the homemade DRAM cells have leaky capacitors, they function adequately, and there are plans to scale up to larger arrays and potentially connect them to a PC.
This achievement demonstrates the feasibility of DIY semiconductor manufacturing in response to RAM shortages, with ambitions to reach fabrication standards of the 1990s or beyond.
