Texas Instruments calculates its US CHIPS Act winnings at $1.6B Texas Instruments is set to receive up to $1.6 billion and as much as $3 billion in loans from good-old Uncle Sam under the CHIPS and Science Act, the US Commerce Department announced on Friday. The award comes two years after President Biden signed into law the $53 billion funding bill, which is supposed to boost domestic …
Just to note, you can sometimes die shrink a dersign by 'one process' of improvement or so tor enlarge by 1 or 2 sometimes) but that's about it,. And for analog circuitry maybe not even that. So these shortages of 65nm chips etc, a while back, even if the capacoty had been there they couldn't ne fabbled at 28nm or like 14 or 7nm instead,
I have read elsewhere that 28nm is the last realm of "planar transistors," and the smaller nodes just implement the FINs (of FINFET) on top of (essentially) this node.
I've also read that planar transistors are more reliable than FINFET (or GAA), and they are obviously more able to dissipate heat into the substrate.
For automobile electronics, where the temperature will be high, FINFET sounds like a bad idea.
Although phones and tablets are big business they're not the only use for processors. This application demands 'the latest' merely because the devices are crammed with bloatware and pushware, they're a sump for resources that primarily runs very badly designed software.
Its only when you strip a bloated system down to the metal that you realize just how fast everyday hardware is.
“ While certainly not as flashy as the leading edge silicon pioneered by the likes of Intel, TSMC, and Samsung, which have received the lion's share of the US CHIPS funds, these older process nodes remain quite relevant, being used in embedded applications ranging from washers and dryers to the engine control units in automobiles.”
… and then shipped to the Far East for component sub-assembly. The security and supply-chain problem is far wider than just High End chip manufacturing.
