Alternative Gate Dielectric Materials [PDF]

ECS Transactions, 2006
Alternative high-k materials are being researched as a replacement for SiON. At present HfSiON is the most popular material because of good transistor performance. Still, issues such as threshold voltage control and a limited k-value improvement encourage continuing material screening. In this paper, we give a short overview of some of the work
