Integrated circuit device with series-connected field effect transistors and integrated voltage equalization and method of forming the device
Abstract:
Disclosed is an integrated circuit device having series-connected planar or non-planar field effect transistors (FETs) with integrated voltage equalization and a method of forming the device. The series-connected FETs comprise gates positioned along a semiconductor body to define the channel regions for the series-connected FETs. Source/drain regions are located within the semiconductor body on opposing sides of the channel regions such that each portion of the semiconductor body between adjacent gates comprises one source/drain region for one field effect transistor abutting another source/drain region for another field effect transistor. Integrated voltage equalization is achieved through a conformal conductive layer having a desired resistance and positioned over the series-connected FETs such that it is electrically isolated from the gates, but in contact with the source/drain regions within the semiconductor body.
