Abstract
Abstract A semiconductor device comprises a substrate including two connected transverse portions having an acute included angle. Mounted on a first surface of one of the substrate portions is a semiconductor pellet. The pellet, and portions of the substrate, with the exception of a second substrate surface, are encapsulated within a solid encapsulating material. An opening extends through the device from a surface of the encapsulating material to the substrate second surface. The substrate first surface is transverse to the said encapsulating material surface and at an acute angle with the substrate second surface.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
40 words
a semiconductor device as in claim 1 wherein said substrate comprises two connected transverse portions having an acute included angle, said first surface being on one of said portions, and said second surface being on the other of said portions.
Claim 2
Dependent Claim
86 words
A semiconductor device as in claim 2 wherein: at least one of said terminals is connected to a portion of said pellet by means of a fine wire bonded to said terminal and said portion; a rubberlike material encapsulating said pellet and fine wire including the junctions of said wire with said terminal and said portion; and an extension of said substrate second surface at the juncture of said two portions providing a lip extending from said first surface, said encapsulating material abutting against said lip.
Claim 3
Dependent Claim
86 words
A semiconductor device as in claim 1 wherein; at least one of said terminals is connected to a portion of said pellet by means of a fine wire bonded to said terminal and said portion; a rubberlike material encapsulating said pellet and fine wire including the junctions of said wire with said terminal and said portion; and an extension of said substrate second surface at the juncture of said two portions providing a lip extending from said first surface, said encapsulating material abutting against said lip.
Claim 4
Dependent Claim
