Abstract
The effects of Ti film thickness and rapid thermal annealing (RTA) amb
ient on the properties of narrow TiSi2 lines were studied. Decreasing
the Ti film thickness improves the critical line width of silicidation
. Excessive nitridation suppresses the silicidation at Ti film thickne
ss thinner than 30 nm in atmosphere N-2 RTA. Using a low-pressure N-2
RTA process (30 mTorr), a 0.10 mu m line width with low resistivity wa
s accomplished at the Ti film thickness of 20 nm without lateral overg
rowth.
