摘要
We compare the reliability of vertical MOSFETs with planar ones. For the first time, the impact of the most striking vertical MOS specific features such as different source/drain engineering, channel orientation, and variable gate oxide thickness on reliability is investigated. Even though LDD is missing, it is shown that scaled down vertical transistors have a sufficient reliability for potential use in gigascale memories.
