Lam Research's Foundry Business Hits New High

Foundry reached record revenues, representing 46% of systems sales versus 44% in the June quarter. Demand came from leading-edge chipmaking and advanced packaging as well as mature-node capacity spending in China.

Korea generated 20% of revenues, unchanged sequentially, while Taiwan accounted for 18%, down from 27%. Lam Research expects China's revenue share to fall significantly in the December quarter.

LRCX Support Revenues Reach Fourth Straight Record

Customer support-related revenues and other reached $2.49 billion, up 40% year over year and 0.6% sequentially. The Customer Support Business Group (“CSBG”) benefited from high equipment utilization, NAND upgrades and demand for spares and services.
