Light-activated semiconductor device package unit

Claim 2

An optoelectronic semiconductor unit comprising, in combination: a semiconductor device having a light-sensitive area; a guide tube having a pair of open ends; a locating fixture mounted on the device and extending outwardly therefrom, said locating fixture having a hole at its outer extremity in alignment with said area, one end of the tube being received in the hole and being in spaced relationship to said area, there being means for sealing the junction between the tube and the fixture; a light pipe removably insertable into the other end of said guide tube for conducting light energy onto said light-sensitive area; and a sealed package, said device and said locating fixture being wholly disposed in the package and said guide tube extending from the locating fixture and through and outwardly of the package, said package being operable for hermetically enclosing said semiconductor device and said one end of said guide tube.

Claim 3

An optoelectronic semiconductor unit as set forth in claim 1, wherein said light pipe comprises a plurality of flexible light-guiding fibers.

Claim 4

An optoelectronic semiconductor unit as set forth in claim 1, and including an electrical lead in electrical contact with said device at a location spaced laterally from the locating fixture, said lead extending through and being electrically isolated from said package.

Claim 5

An optoelectronic semiconductor unit as set forth in claim 1, including means sealing the junction between the device and the fixture.

Claim 6

An optoelectronic semiconductor unit as set forth in claim 1, and including a light-transparent sealant within the hole and in covering relationship to said light-sensitive area.

Claim 7

An optoelectronic semiconductor unit as set forth in claim 1, wherein said fixture is formed from a light-transparent material and engages said device, said hole being in the fixture terminating at a location within the fixture.

Claim 8

An optoelectronic semiconductor unit as set forth in claim 1, wherein is included a light-transparent plate between the fixture and the device, said recess including a hole through the fixture in alignment with said light-sensitive area.

Claim 9

An optoelectronic semiconductor unit comprising, in combination: an enclosure including a top cover member having a first flange, a bottom cover member spaced from the top cover member and having a second flange, and an insulator member between said first and second flanges, one of said members having an opening therethrough, said top cover defining a first electrode having a first contact area, said bottom cover defining a second electrode having a second contact area; an optoelectronic semiconductor device having a photosensitive region and disposed between and in electrical contact with said first and second contact areas; and optical interface means, including a guide tube having a pair of open ends and extending through said opening, a locating fixture wholly disposed within the enclosure and having a hole aligned with said photosensitive region, one end of the guide tube being in the hole and spaced from said region, the guide tube being hermetically sealed to the fixture over said photosensitive region, said guide tube adapted to receive a light-guiding pipe for directing light energy onto said region.

Claim 10

An optoelectronic semiconductor unit comprising, in combination: an enclosure including a top cover member having a first flange, a bottom cover member spaced from the top cover member and having a second flange, and an insulator member between said first and second flanges, one of said members having an opening therethrough, said top cover defining a first electrode having a first contact area, said bottom cover defining a second electrode having a second contact area; an optoelectronic semiconductor device having a photosensitive region and disposed between and in electrical contact with said first and second contact areas; and optical interface means, including a guide tube having a pair of open ends and extending through said opening, a locating fixture wholly disposed within the enclosure and having a hole aligned with said photosensitive region, one end of the guide tube being in the hole and spaced from said region, the guide tube being hermetically sealed to the fixture over said photosensitive region, said guide tube adapted to receive a light-guiding pipe for directing light energy onto said region.

Claim 11

An optoelectronic semiconductor unit as set forth in claim 8, wherein said opening is in said top cover member.

Claim 12

An optoelectronic semiconductor unit as set forth in claim 8, wherein said opening is in said insulator member.
