I just think it's ironic that GF failed on their own to even develop the 14 nm process. They failed and flailed to do this on their own. Then they tucked their tail between their legs and went to Samsung to purchase a working process. I'm assuming this is the highest revenue process at GF. The 14 nm AMD processors that are shipping in high volume from Malta. Soon to slow down considerably as the 7 nm ramps up big time at TSMC.
Then you go and sue someone that has actually been able to develop several working process nodes on their own. I'm someone that respects the capability to do things right. I think the only reason GF has patents is because IBM paid GF 1.5 billion to take all the failed fabs off their hands. IBM did make several semi innovations over the years. I assume these IBM patents are the ones being sued over? https://www.globalfoundries.com/news-events/press-releases/globalfoundries-completes-acquisition-of-ibm-microelectronics-business. That's the funniest thing I've ever heard of in my life. A company pays another company 1.5 Billion dollars to take a biz off of their hands.
Because before IBM they couldn't even design one node from scratch. Oh, and after IBM they failed and floundered on 7nm. Instead of buying from Samsung again, they gave up and pivoted.
The end is near for the GloFo. I'm sure the prince is close to doing a full cut off of any extra dollars.
