摘要

The gate oxide scalability of high performance CMOS transistor has been investigated. In terms of gate leakage, the T/sub ox/ can be scaled down to at least 8 /spl Aring/ with I/sub G/ not exceeding I/sub off/ limit suggested by ITRS. To reduce boron penetration, remote-plasma-nitridation (RPN) oxides were studied. Devices with RPN oxides showed excellent resistance against boron penetration, improved hole mobility, reduced gate leakage, and improved transistor performance. The gate oxide scalability can be extended using the RPN process.
