Abstract
Abstract An array of radiation sensing devices, each including a pair of conductor-insulator-semiconductor capacitors, arranged in rows and columns in which the row stripes or lines form row connected capacitors in relation to selected surface regions of a semiconductor substrate and in which the column stripes or lines form column connected capacitors in relation to the selected surface regions. Each of the row stripes overlies first portions of the selected surface regions of a respective row. Each of the column stripes overlies entirely the selected surface regions of a respective column.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
153 words
A semiconductor device comprising a substrate of semiconductor material having a major surface, a thick layer of insulating material overlying said major surface and having a thin portion of rectangular outline, said thin portion overlying a rectangular region in said major surface of identical outline, a conductor having a pair of parallel sides overlying said rectangular thin portion of said insulating material, said sides being orthogonal to and extending from one side of said thin rectangular portion to the opposite side thereof and being included between and spaced from the other sides of said thin rectangular portion, said conductor forming a first conductor-insulator-semiconductor capacitor with said rectangular thin portion of said insulating layer and said substrate, a second conductor insulated from said first conductor and entirely overlying said thin rectangular portion of said insulating layer to form a second conductor-insulator-semiconductor capacitor with said rectangular thin portion of said insulating layer and said substrate.
Claim 2
Dependent Claim
