Abstract
Abstract An article having two parts bonded together includes an intermediate member between opposed surfaces of the two parts. The intermediate member has a plurality of openings therethrough which are filled with a bonding material. The opposed surfaces of the two parts engage opposed surfaces of the intermediate member and the bonding material is adhered to the opposed surfaces of the two parts to bond them together. The intermediate member provides control of the spacing between the two parts and the positional relationship of the two parts.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
117 words
An array of laser diodes comprising a pair of laser diodes each being a body of semiconductor material having top and bottom surfaces and an edge surface from which light is adapted to be emitted, said diodes being arranged with the top surface of one being in spaced opposed relation to the bottom surface of the other, an intermediate member between said opposed surfaces of the laser diodes and having a separate surface contacting each of said opposed surfaces of said laser diodes, said intermediate member having a plurality of openings therethrough, and a bonding material in the openings in the intermediate member and adhered to the opposed surfaces of said diodes to secure the diodes together.
Claim 2
Dependent Claim
117 words
An array of laser diodes comprising a pair of laser diodes each being a body of semiconductor material having top and bottom surfaces and an edge surface from which light is adapted to be emitted, said diodes being arranged with the top surface of one being in spaced opposed relation to the bottom surface of the other, an intermediate member between said opposed surfaces of the laser diodes and having a separate surface contacting each of said opposed surfaces of said laser diodes, said intermediate member having a plurality of openings therethrough, and a bonding material in the openings in the intermediate member and adhered to the opposed surfaces of said diodes to secure the diodes together.
Claim 3
Dependent Claim
18 words
An array in accordance with claim 1 in which the intermediate member is of an electrically conductive material.
Claim 4
Dependent Claim
26 words
An array in accordance with claim 2 in which the bonding material is of an electrically conductive material to electrically and mechanically connect said laser diodes.
Claim 5
Dependent Claim
60 words
An array in accordance with claim 3 in which each of said laser diodes is a body in the form of a parallelepiped having regions of opposite conductivity type forming a PN junction therebetween which extends to a light emitting edge of the body and the top and bottom surfaces of the diodes are substantially parallel to said PN junction.
