Abstract
Abstract A semi-conductor device including a housing for a semi-conductor body of the field-effect type having an insulating gate electrodes and electric conductors which emerge from the housing and are located in a circle. The conductors are surrounded by a closed, flexible ring of an electrically conductive rubber material such as electrically conductive silicon rubber, e.g., a rubber mixed with electrically conductive particles. This ring is so flexible that it contacts all of the conductors without substantially bending them.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
87 words
A semiconductor device comprising a housing, a semiconductor body consisting of a field-effect transistor of the type having an insulating gating electrode, and electric conductors connected to said semiconductor body which emerge on one side of the housing and are located at least in situ on the periphery of a circle, and a closed resilient ring surrounding the electric conductors consisting of an electrically conductive rubber material, the ring having such a resiliency that it contacts all of said electric conductors without substantially bending the electric conductors.
Claim 2
Dependent Claim
