Method of installing a window member of an infrared detector
First Claim
1. A method of fixing a window member to a can of an infrared detector over an incident opening extending through a surface of said can, said can comprising electrically conductive material and having a sensing element body disposed therein, and said window member having first and second opposing end surfaces and a side circumferential surface extending between said first and said second surfaces, said window member having a layer of electrically conductive material between said first and second surfaces forming a portion of said side circumferential surface, said method comprising:
- adhering said window member to said surface of said can over said incident opening by providing electrically non-conductive adhesive between said can at a circumferential surface of said can that surrounds said incident opening and said window member at the periphery of said first end surface thereof and on at least part of said portion of said side circumferential surface that is formed by said layer of electrically conductive material thereby leaving at least part of said portion of said side circumferential surface that is formed by said layer of electrically conductive material free from said electrically non-conductive adhesive;
covering said second end surface of said window member with a mask;
subsequently applying a continuous electrically conductive thin film on said surface of said can to which said window member is adhered, on said mask covering said second end of said window member and on said part of said portion of said side circumferential surface of said window member that is free from said electrically non-conductive adhesive; and
separating said electrically conductive thin film applied on said mask from the remainder of said continuous electrically conductive thin film, and removing said mask with said electrically conductive thin film thereon from said second surface of said window member.

Abstract
A method for fixing a window member having a layer of electrically conductive material to a can of an infrared detector over an incident opening extending through a surface of the can is performed by adhering the window member to the can with a non-conductive adhesive applied between an end surface and a side circumferential surface of the window member and a surface of the casing while leaving a portion of the side circumferential surface, formed by the electrically conductive material layer, partially exposed, masking an opposing end surface of the window member and then covering the result with a thin film of electrically conductive material part of which extends between the exposed side circumferential surface of the electrically conductive material layer of the window member and the surface of the can. Finally, the mask and the portion of the thin film of electrically conductive material covering the mask are removed.
