*semiconductor · news · 2024-11-12 · PhoneArena*

## Key points

- Samsung Foundry's second-generation 3nm GAA yields have dropped to just 20 percent.
- Samsung's first-generation 3nm node achieved only 50-60 percent yield, short of the industry-competitive threshold.
- Low yield has caused even South Korean chip designers to switch from Samsung Foundry to TSMC.
- Samsung is now developing a 2nm node codenamed 'Ulysses' for a potential 2027 Galaxy S27 debut.

**Companies:** Samsung, TSMC
**Countries:** South Korea
