Abstract
Abstract A dual-in-line type device comprises an elongated, rectangular envelope. Emerging from each of two opposed, elongated sides of the envelope is a row of leads. Disposed along the other elongated envelope sides are a pair of elongated shield members having end portions disposed along the end sides of the envelope. The shield end portions are secured to conductive members extending outwardly through the end sides. Within the envelope, a semiconductor pellet is mounted on a substrate connected to the conductive members.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
36 words
A semiconductor device as in claim 1 wherein said end portions of said shield members are electrically connected at each end of said envelope to form a closed loop of said shield members about said envelope.
Claim 2
Dependent Claim
69 words
A semiconductor device as in claim 1 in which said elongated conductor has two end members projecting outwardly of said envelope through said end sides thereof, and the end portion of each of said shield members at opposite ends of said envelope is electrically connected to the projecting end member at each of said envelope end sides to form a closed loop of said shield members about said envelope.
Claim 3
Dependent Claim
74 words
A semiconductor device as in claim 1 in which said elongated conductor has two end members projecting outwardly from said envelope through said end sides thereof, and a lead connected to each of said end members, and one end portion only of each of said shield members is electrically connected to either of said conductor end members, whereby the leads connected to said end members are not electrically connected together via said shield members.
Claim 4
Dependent Claim
49 words
A semiconductor device as in claim 1 wherein: all of said leads extend in the same general direction towards one of said shield members and away from the other of said shield members, and said one shield member has a width less than the other of said shield members.
Claim 5
Dependent Claim
75 words
A semiconductor device as in claim 1 wherein: all of said leads extend in the same general direction towards one of said shieLd members and away from the other of said shield members, and the thickness of said envelope between the line of emergence of said rows of leads from said envelope and said one shield member being less than the thickness of said envelope between said line of emergence and said other shield member.
Claim 6
Dependent Claim
39 words
A semiconductor device as in claim 1 in which said lead is integral with said end member of said elongated conductor, and is disposed in said one row at a position beyond said one end side of said envelope.
