Abstract
Abstract A novel case is capable to receive a plurality of semiconductor devices. A case comprises a metallic base and a metallic cover separated one from another by means of a hollow insulating body constituting a receptacle. Said enclosure further comprises an intermediary support located inside said receptacle and carrying itself a certain number of devices which are added to those which are normally soldered to the base of the case.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
122 words
A case for semiconductor devices comprising at least one assembly constituted of a first metallic base and a metallic cover, a first insulating hollow body for separating said base from said cover and constituting a receptacle capable to receive at least a first semiconductor device, a part of said base being electrically connected with said first device; said case further comprising at least a second hollow body having the shape of a ring made of insulating heat conductive material, constituting a support located inside said receptacle, having a first face secured to said first base and a second face opposite to said first face; at least one area of said second face being metallized to receive at least one second semiconductor device.
Claim 2
Dependent Claim
122 words
A case for semiconductor devices comprising at least one assembly constituted of a first metallic base and a metallic cover, a first insulating hollow body for separating said base from said cover and constituting a receptacle capable to receive at least a first semiconductor device, a part of said base being electrically connected with said first device; said case further comprising at least a second hollow body having the shape of a ring made of insulating heat conductive material, constituting a support located inside said receptacle, having a first face secured to said first base and a second face opposite to said first face; at least one area of said second face being metallized to receive at least one second semiconductor device.
Claim 3
Dependent Claim
28 words
A case according to claim 1 further comprising a second metallic base secured to said second face and capable to carry a third insulating heat conductive hollow body.
Claim 4
Dependent Claim
61 words
A case according to claim 1, further comprising at least an insulating heat conductive stud having a lower face secured to said first base inside said support, and an upper face, said upper face of said stud having at least a metallized zone to receive at least a third semiconductor device, said metallized zone being electrically connected with said first base.
Claim 5
Dependent Claim
52 words
A case according to claim 1, further comprising a plurality of semiconductor devices carried by said base and said support, interconnected with one another, first electrode of first device being connected to said first base, and second electrode of at one last of said plurality of devices being connected to said cover.
