Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
An active pellet comprising a semiconductor body; a plurality of diffused layers formed on said body; a plurality of electrodes having their one ends connected to said diffused layers and extending over the lateral side surfaces of said body; and a mounting plate having external terminals formed thereon; said body having its surface on which said diffused layers are formed placed on said mounting plate so that said electrodes on said body surface contact said terminals on said mounting plate, with those portions of said electrodes extending over the lateral sides of said body being bonded to said terminals on said mounting plate.
Claim 2
Dependent Claim
103 words
An active pellet comprising a semiconductor body; a plurality of diffused layers formed on said body; a plurality of electrodes having their one ends connected to said diffused layers and extending over the lateral side surfaces of said body; and a mounting plate having external terminals formed thereon; said body having its surface on which said diffused layers are formed placed on said mounting plate so that said electrodes on said body surface contact said terminals on said mounting plate, with those portions of said electrodes extending over the lateral sides of said body being bonded to said terminals on said mounting plate.
Claim 3
Dependent Claim
104 words
An active device pellet comprising a semiconductor body including a semiconductor base, said body having a first surface and a plurality of lateral surfaces adjoining said first surface; at least one diffused layer formed on said first surface; a first electrode formed on said first surface in contact with said diffused layer; a second electrode formed on said body having a first end formed on and connected to said semiconductor base and a second end extending to and formed on said first surface, both of said first and said second electrodes additionally having portions thereof formed on at least one of said lateral surfaces.
Claim 4
Dependent Claim
104 words
An active device pellet comprising a semiconductor body including a semiconductor base, said body having a first surface and a plurality of lateral surfaces adjoining said first surface; at least one diffused layer formed on said first surface; a first electrode formed on said first surface in contact with said diffused layer; a second electrode formed on said body having a first end formed on and connected to said semiconductor base and a second end extending to and formed on said first surface, both of said first and said second electrodes additionally having portions thereof formed on at least one of said lateral surfaces.
Claim 5
Dependent Claim
28 words
The pellet of claim 2 wherein said semiconductor base comprises a high concentration wafer and said diffused layer is formed on an epitaxial layer formed on said wafer.
Claim 6
Dependent Claim
81 words
The pellet of claim 2 in combination with a mounting plate member having terminals formed thereon, wherein said pellet body has its first surface on which said first and second electrodes appear placed on said mounting plate member so that first and second electrodes contact said terminals on said mounting plate, with those portions of said first and second electrodes which extend over at least one lateral surface of said pellet body being bonded to said terminals on said mounting plate.
