No, it means there will be even worse touchscreens because now automakers can't afford silicon that might actually power a tablet.
How can they not afford a 300 dollar tablet in a 40k dollar car?
TSMC to customers: It's time to stop using older nodes and move to 28nm

I'm also interested in the migration costs. Perhaps there will be a market for a migration service... though the TAM on that is probably small enough that it can't support a product-first approach.
Migration services exist today. Almost any of the ASIC backend service companies would take a contract to do a fab port. (Won't be cheap, though) But these are services, not products. There's no one-size-fits-all way to move design Z from process X to process Y, for arbitrary values of X, Y and Z, nor is there ever likely to be. And even once it's done, there are still costs to verify and test the results, which isn'…
I can imagine its even more so in the automotive industry, where there's strict safety regulations and guidelines in place which must be met.

#43Thanks TSMC... when will you release a HV version of 28nm? Oh... never, because you transitioned to bottom poly at 40nm. How is your automotive eFlash at 28nm... oh, you're still working on it (since 2018)? Well, guess we won't have many display drivers (or displays) or autos then, or maybe marketing should pull their heads out and smell the roses. I mean, I get it. Most things should transition to 28nm on 300mm wafe…
That will leave some decent spare capacity for automotive.
And maybe when a lot of such chips would be done in 28nm, it would make sense for TSMC to invest more in optimizing the process for them.

I honestly don't really understand 95% of what you've written here, but could this mean an end of godawful touch screens in cars?
No, it means there will be even worse touchscreens because now automakers can't afford silicon that might actually power a tablet.

That's scary - I have a < 1 yr old Tesla model Y and it is embarrassing how underpowered the tablet that controls basically every part of the car is.

Depends on the design. Did you throw RTL at a layout engine and let it figure it out? Pretty damn close to automated and could get to automated with a little upfront elbow grease by a company specializing in such things. Heavy analog design? It's going to be a lot more work.
Maybe my intuition is completely wrong here, but would the analog case be simplified if the target node+technology was chosen to have trace widths exactly 1/2 the size of the node being transitioned from? I.e. the traces would have essentially the same standing-wave tuning requirements when modelled as waveguides; would catch a harmonic of the original frequency when acting as antennae; etc.

#48It reminds me of how this backwards way of thinking seems to have infested everyone's heads; that stuff has to be, or make use of, the very latest technology available, or it will be useless junk that barely works.
Re: TSMC to customers: It's time to stop using older nodes and move to 28nm
#49Dumb question: if something is being manufactured on 60nm today, can you not just take the same design and start manufacturing it on 28nm? Or do you need to literally redesign the entire circuit?
You can't take a tube radio and manufacture it with opamps without substantial design changes.
Samsung is starting to use GAA right now, and TSMC will use it for the next process node.
