Hh. Tseng et al., Jet vapor deposition nitride processing and application to advanced CMOS devices for reduction of gate leakage current and boron penetration, MAT SC S PR, 3(3), 2000, pp. 173-178
The increase in gate leakage current and boron penetration are major proble
ms for scaled gate dielectrics in advanced device technology. We have demon
strated, for the first time, reduction in gale leakage current and strong r
esistance to boron penetration when jet vapor deposition (JVD) nitride is u
sed as a gate dielectric in an advanced CMOS process. JVD nitride provides
a robust interface in addition to well behaved bulk properties, MOSFET char
acteristics and ring oscillator performance. Process optimization is discus
sed. Manufacturing issues remain to be addressed. (C) 2000 Elsevier Science
