Static pass transistor logic with transistors with multiple vertical gates |
摘要 |
Static pass transistor logic having transistors with multiple vertical gates are described. Multiple vertical gates are edge defined with only a single transistor being required for multiple logic inputs. Thus a minimal surface area is required for each logic input. The static pass transistor includes a transistor which has a horizontal depletion mode channel region between a single source and drain region. A number of vertical gates are located above different portions of the depletion mode channel region. A vertical gate is located above a first portion of the depletion mode channel region and is separated therefrom by a first insulator material. A vertical gate is located above a second portion of the channel region and is separated therefrom by a second insulator material. There is no source nor drain region associated with each input and the gates have sub-lithographic horizontal dimensions by virtue of being edge defined vertical gates. |
