  • Method for forming a bipolar transistor stabilized with electrical insulating elements
    Patent number: 6451659
    Abstract: A semiconductor component of the heterojunction bipolar transistor type comprises, on a substrate, a collector, a base and a mesa-shaped emitter resting on the base. The bipolar transistor furthermore comprises electrically insulating elements in contact with the base and the flanks of the emitter mesa, said elements having a width of the same magnitude as the width of the mesa and providing the component with greater stability. Furthermore, a method for the manufacture of a component of this kind comprises in particular a step for the ion implantation of insulating ions through the constituent layer of the emitter mesa so as to define the electrically insulating elements.
    Type: Grant
    Filed: December 3, 1999
    Date of Patent: September 17, 2002
    Assignee: Thomson-CSF
    Inventors: Sylvain Delage, Simone Cassette, Achim Henkel, Patrice Salzenstein
