Samsung said the chip investment will create 15,000 jobs. The firm's heir apparent Jay Y. Lee, awaiting a Supreme Court decision on his bribery conviction, has been under pressure from the government to help create more jobs, as Asia's fourth-largest economy is battling rising numbers of jobless college graduates partly due to slowing economic growth. South Korea, the world's biggest producer of memory chips thanks to Samsung and domestic rival SK Hynix Inc, also wants to reduce its reliance on memory chip sales to smoothen volatile export trends.
