I’m not hooked on building desktop CPUs at home or anything. It could be 3 um, 1 MHz and I’d be happy. It doesn’t even have to be semiconductors. We had vacuum tubes and core memory before transistors. The modern fab is optimized for density, perf, and power. Prioritize ease of fabrication and maybe you get a process or substrate that looks radically different from today’s commercial fabs. Or maybe we adopt a 500 nm node and stop there :-) |
