Abstract
Abstract A method of preparing photodetector array elements from a body of photodetector material wherein conductive layers of a metal are formed on selected portions of a substrate, the conductive layers are coated with a photoresist material, an adhesive layer is deposited on the photoresist and the remaining substrate, a body of photodetector material is bonded to the adhesive, and individual photodetector elements are delineated from the body to form the elements of the array and to expose the edges of the photoresist material, and the photoresist layer and material deposited thereon are removed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
98 words
A method of preparing photodetector array elements from a body of photodetector material, comprising: forming conductive layers on selected portions of a substrate; coating said conductive layers with a photoresist material; depositing an adhesive layer on the photoresist and the remaining substrate to a sufficient depth to cover said photoresist; bonding a body of photodetector material to said adhesive, such that said body is parallel to said substrate; delineating individual photodetector elements from said body to form elements of an array, thereby exposing the edges of said photoresist material; and removing the photoresist layer and material deposited thereon.
Claim 2
Independent Claim
98 words
A method of preparing photodetector array elements from a body of photodetector material, comprising: forming conductive layers on selected portions of a substrate; coating said conductive layers with a photoresist material; depositing an adhesive layer on the photoresist and the remaining substrate to a sufficient depth to cover said photoresist; bonding a body of photodetector material to said adhesive, such that said body is parallel to said substrate; delineating individual photodetector elements from said body to form elements of an array, thereby exposing the edges of said photoresist material; and removing the photoresist layer and material deposited thereon.
Claim 3
Dependent Claim
14 words
A method of claim 1 wherein said adhesive layer is about 0.01 millimeters thick.
Claim 4
Dependent Claim
17 words
The method of claim 2 wherein said adhesive layer ranges from 0.001 millimeters to 0.02 milliters thick.
Claim 5
Dependent Claim
23 words
The method of claim 1 wherein said adhesive layer remaining on said individually delineated photodetector elements is thicker than the photodetector element itself.
Claim 6
Dependent Claim
21 words
The method of claim 1, including the subsequent step of interconnecting said elements to said conductive layers to form an array.
