Cost of Semiconductor Manufacturing

• $30M to develop 65nm devices, $500M to develop 3 nm [1]
• $170M to produce 90 nm in Indiana. [2]
• Arduino is 350 nm [3] - 'wouldn't be asking on Reddit if it mattered'
• Original Nintendo was 8 bit. 32 bit microprocessors such as 8 Core 80Mhz are 350 nm [4] - 2006
• $4M design and $200k tooling for 130 nm [5]
