Abstract
Abstract A package for solid state image sensor devices, such as CCD image sensors, includes a base plate on which a plurality of the image sensor devices are mounted in end-to-end abutting relation with the detector arrays of the image sensors being over an opening in the base plate, and a cover mounted on the base plate and extending over the image sensor devices to enclose the image sensor devices between the cover and the base plate. The base plate and cover are of polycrystalline silicon so as to have a coefficient of thermal expansion which matches that of the image sensor devices.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
106 words
A package for solid state image sensors comprising, a base plate of silicon having a flat surface and an opening therethrough, a plurality of image sensor devices mounted on said surface of the plate and in close proximity to each other, each of said image sensor devices including a silicon substrate having an array of detectors therein, said image sensor devices being mounted on the base plate with the detector array being exposed through said opening, and a cover mounted on said base plate and extending over said image sensor devices so as to enclose said image sensor devices between the cover and the base plate.
Claim 2
Dependent Claim
106 words
A package for solid state image sensors comprising, a base plate of silicon having a flat surface and an opening therethrough, a plurality of image sensor devices mounted on said surface of the plate and in close proximity to each other, each of said image sensor devices including a silicon substrate having an array of detectors therein, said image sensor devices being mounted on the base plate with the detector array being exposed through said opening, and a cover mounted on said base plate and extending over said image sensor devices so as to enclose said image sensor devices between the cover and the base plate.
Claim 3
Dependent Claim
14 words
A package in accordance with claim 1 in which said cover is of silicon.
Claim 4
Dependent Claim
18 words
A package in accordance with claim 2 in which the base plate and cover are of polycrystalline silicon.
Claim 5
Dependent Claim
22 words
A package in accordance with claim 1 in which the base plate is a flat rectangular plate having an elongated opening therethrough.
Claim 6
Dependent Claim
22 words
A package in accordance with claim 4 in which the image sensor devices are mounted over said opening in end-to-end abutting relation.
Claim 7
Dependent Claim
30 words
A package in accordance with claim 5 in which the base plate has on said surface conductive lines and wires electrically connecting the image sensor devices to said conductor lines.
Claim 8
Dependent Claim
43 words
A package in accordance with claim 4 including a window secured to the outer surface of the base plate and extending across the opening, said window being of a material which is transparent to the radiation being sensed by the image sensor devices.
