Abstract
Official abstract text for this publication.
An integrated circuit electrical protection device is disclosed that includes a semiconductor substrate and a plurality of transistor fingers partitioned into a plurality of segments. The segments are distinguished from one another by well-ties spaced apart from each other within a source/drain region that is shared by adjacent segments.
First claim
Opening claim text (preview).
What is claimed is: 1. An integrated circuit device comprising: a Field Effect Transistor (FET) comprising a first transistor finger and a second transistor finger, wherein the first transistor finger and the second transistor finger share a first source/drain region of a first conductivity type residing in a well region having a second conductivity type, wherein the first conductivity type is opposite the second conductivity type; and a first well-tie between a first portion of…
