Abstract
Abstract A solid state image pick-up device is provided in which a photoelectric conversion element is configured so that a light reception portion of the photoelectric conversion element is covered with a member of light transmissible glass. A frame, used as a package, is filled with synthetic resin by a potting method, and the synthetic resin is solidified so that the frame, the peripheral portions of the glass member, and the photoelectric conversion element are integrally combined with each other. By so doing, the light transmission property of the photoelectric element can be properly made, excellent moisture resistance can be obtained, and improved reliability of the device results. Further, a method of manufacturing the solid state image pick-up device of the present invention is provided.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
142 words
A solid state image pickup device comprising: photoelectric conversion means for performing photoelectric conversion on the basis of a quantity of light incident onto a light reception portion thereof; light transmissible means in contact with said photoelectric conversion means, for covering said light reception portion of said photoelectric conversion means, while allowing said portion to receive light; support means, surrounded by a bottom wall and side walls, for supporting said photoelectric conversion means and said light transmissible means, said light transmissible means and said support means being fixedly integrated in the device so that at least a gap remains at said side walls, and said support means comprising positioning means having first and second steps provided at different heights thereon; and wherein a synthetic resin is filled in said gap by potting so as to cover at least said photoelectric conversion means.
Claim 2
Dependent Claim
142 words
A solid state image pickup device comprising: photoelectric conversion means for performing photoelectric conversion on the basis of a quantity of light incident onto a light reception portion thereof; light transmissible means in contact with said photoelectric conversion means, for covering said light reception portion of said photoelectric conversion means, while allowing said portion to receive light; support means, surrounded by a bottom wall and side walls, for supporting said photoelectric conversion means and said light transmissible means, said light transmissible means and said support means being fixedly integrated in the device so that at least a gap remains at said side walls, and said support means comprising positioning means having first and second steps provided at different heights thereon; and wherein a synthetic resin is filled in said gap by potting so as to cover at least said photoelectric conversion means.
Claim 3
Dependent Claim
128 words
A solid state image pickup device comprising: photoelectric conversion means for performing photoelectric conversion on the basis of a quantity of light incident onto a light reception portion thereof; covering means, coupled to said photoelectric conversion means, for light-transmissibly covering at least said light reception portion of said photoelectric conversion means to allow light to be received by said conversion means; a frame, surrounded by a bottom wall and side walls, for use as a package for said photoelectric conversion means and said covering means so as to keep a gap at least against said side walls, wherein synthetic resin is inserted in said gap by potting and solidified so as to fixedly integrate said covering means and said frame, and to cover at least said conversion means.
