  • Semiconductor device having sealed electrical feedthrough
    Patent number: 5041900
    Abstract: A method of hermetically sealing an electrical feedthrough (5) in a semiconductor-on-insulator device comprising the steps of producing an electrically insulating layer (2) on a semiconductive material (1) having a first surface area, producing one or more electrodes (4) on a non-conductive substrate (3) of a second surface area which may be greater than the first surface area, with each electrode having an electrical feedthrough (5) associated therewith, placing the semiconductive layer on the substrate with the insulating layer in contact with the substrate and such that each electrical feedthrough extends beyond the edge of the semiconductive layer, and bonding the semiconductive layer to the substrate to provide an hermetic seal around the feedthrough and thus protect the integrity of the electrode associated therewith and disposed between the semiconductive layer and the substrate.
    Type: Grant
    Filed: June 15, 1989
    Date of Patent: August 20, 1991
    Assignee: Hamilton Standard Controls, Inc.
    Inventors: Frank Chen, Tony W. Rogers, David E. Blackaby
  • Method of making capacitive pressure sensors
    Patent number: 4908921
    Abstract: A method of batch producing capacitive pressure sensors in which a sheet of semiconductive material is provided with an insulating layer 4 on one side thereof and a plurality of cavities 1 are formed in the semiconductive sheet by removing part of the insulating layer and part of the semiconductive sheet. Simultaneously with producing the cavities in the semiconductive sheet, at least one recess is provided, again by removing part of the insulating layer and part of the semiconductive sheet.
