Rapid thermal processing (RTP) technology has made significant advance
s in recent years. Dynamic feedback, multizone control, and axially sy
mmetric chamber design have helped to improve manufacturability and pr
ocess control. This article will discuss historical and state-of-the-a
rt RTP technology. Throughput and cycle time for conventional CMOS pro
cesses in RTP and batch furnaces will be compared. Cost of ownership (
COO) for thermal processors will be discussed, highlighting the import
ance of throughput.
