My post was only brief and I knew what happened to the Singaporean Semi conductors industry. And its takes decades toe mature. But well I will again keep my answer brief will talk on this later.
Well there is no need to talk actually.
To have a semi conductor industry you will have to overhaul your entire education system. Without talents it's useless.
Putting nuclear reaction aside, 3 technology we consider to be crown jewel of engineering.
1. The magic cloke of jets - Radar absorbing materials
2. Crystal turbine blades - Blood line of entire aviation industry
3. Micro processors & their connecting sockets - heart bit of entire telicom industry
Without having a massive talent pool, you will never figure out the first chapter of those technology's chemistry . Throw all the money you want.
