20110049624 | MOSFET ON SILICON-ON-INSULATOR REDX WITH ASYMMETRIC SOURCE-DRAIN CONTACTS - A semiconductor device is disclosed that includes a silicon-on-insulator substrate including a buried insulator layer and an overlying semiconductor layer. Source extension and drain extension regions are formed in the semiconductor layer. A deep drain region and a deep source region are formed in the semiconductor layer. A first metal-semiconductor alloy contact layer is formed using tilted metal formation at an angle tilted towards the source extension region, such that the source extension region has a metal-semiconductor alloy contact that abuts the substrate from the source side, as a Schottky contact therebetween and the gate shields metal deposition from abutting the deep drain region. A second metal-semiconductor alloy contact is formed located on the first metal-semiconductor layer on each of the source extension region and drain extension region. | 03-03-2011 |

20120187492 | BULK SUBSTRATE FET INTEGRATED ON CMOS SOI - An integrated circuit is provided that integrates an bulk FET and an SOI FET on the same chip, where the bulk FET includes a gate conductor over a gate oxide formed over a bulk substrate, where the gate dielectric of the bulk FET has the same thickness and is substantially coplanar with the buried insulating layer of the SOI FET. In a preferred embodiment, the bulk FET is formed from an SOI wafer by forming bulk contact trenches through the SOI layer and the buried insulating layer of the SOI wafer adjacent an active region of the SOI layer in a designated bulk device region. The active region of the SOI layer adjacent the bulk contact trenches forms the gate conductor of the bulk FET which overlies a portion of the underlying buried insulating layer, which forms the gate dielectric of the bulk FET. | 07-26-2012 |
