Samsung will rule ARM world:
1.) they have their own fabs
they are foundry and IDM;
and they compete directly with their customers (Apple)
2.)they leverage NAND, LPDRAM and display cutting out the middleman
Apple gave Samsung business and they created a monster.
It's going to be a repeat when Samsung entered the DRAM market about 25 (?) years ago.
"Only analog/power semi guys will stay and digital is pretty much owned by a few."
IMHO that's exactly why TI quit mobile business
Fabless-foundry model is broken and TSMC is recently quoting the mask NRE of 16/14nm finfet over $10M. Even this goes down to below $10M over time, the NRE for 10nm or 7nm will be prohibitable for many except a few like Qualcomm, Apple, Samsung and maybe Nvidia, Broadcom and Marvell. The rest will be consolidated and disappear. Only analog/power semi guys will stay and digital is pretty much owned by a few.
NXE is EUV, NXT is 193 nm immmersion. I think it's a little early to spend much time thinking about 7 nm node today. But if we only have the currently expected EUV technology, we would have to use double patterning.
