Abstract
An integrated circuit analog crosspoint switch FET array which utlilizes considerably reduced silicon substrate area than previously. In a preferred embodiment, pairs of the separate diffused regions of different FETs which are connected to the same input are common, forming separate single diffused regions. The separate single diffused regions and the central single diffused regions alternate continuously in a row, separated by the channel regions forming the various transistors. The result is a continuous row of transistors having common diffused regions, except for the transistors at the end of the row, which have their outer diffused regions not in common with any other.
