Genuine question-
How does Govt picking winners and losers going to help?
Intel is no Too big to fail Bank. Why save Intel of all chip manufacturers? Wouldnt it be like 25 years too late, with Intel and its heydays !?
Would Govt now ensure parity by investing in "marquee" entities across different industrial domains?
There is only 1 winner and 1 loser: Intel.
It's the only chip manufacturer "left" in the US. The argument is national security: the US expects China to invade Taiwan and this will kill TSMC in the process.
Whether this will happen or not can be debated, but this is what the government expects.
> It's the only chip manufacturer "left" in the US
Global Foundries, Micron, and Texas Instruments all come to mind
GF is a few nodes behind. Micron doesn't make semiconductors, they mostly make flash and whatnot. TI doesn't have the capacity or knowledge to expand to Intel's size/capacity

All that stuff is still semiconductors, just with different patterns printed on them.
You're right but also wrong. Flash is just semiconductors etched in a different pattern than logic, but you don't print on semiconductors. Semiconductors are 'printed' on wafers via photolithography.
Intel's wafers are made of silicon, which is a semiconductor. Silicon on sapphire hasn't been widely used for a long time, if that's what you're thinking of. Photolithography prints resists on semiconductor wafers which are then used to pattern the next process step, such as wet etching, plasma etching, oxide growth, epitaxial polysilicon growth, ion implantation, etc. These mostly remove semiconductor from the wafer or alter its properties.
Interesting, I hadn't known that silicon is itself a semiconductor before all the circuits are added. Am I correct in saying that the etching process transforms a single semiconductor into billions?
No, silicon is still just one semiconductor, just like water is just one liquid. The substrate is still just one piece of silicon, despite having many silicon semiconductor devices fabricated in it. Polysilicon layers may or may not be additional pieces of silicon.
