Patents by Inventor Dimitri Olofsson

Dimitri Olofsson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Bipolar transistor with polysilicon dummy emitter
    Patent number: 6153919
    Abstract: A manufacturing method for semiconductor components is disclosed which will allow better precision in the definition of the doped areas of the components and the separation of differently doped areas. A selectively shaped area of, for example, polysilicon, defining the area or areas to be doped, is deposited on the component before the masks are applied. This makes the fitting of the masks less critical, as they only have to be fitted within the area of the polysilicon layer. In this way an accuracy of 0.1 .mu.m or better can be achieved.
    Type: Grant
    Filed: January 26, 1999
    Date of Patent: November 28, 2000
    Assignee: Telefonaktiebolaget LM Ericsson
    Inventors: H.ang.kan Sjodin, Anders Soderbarg, Nils Ogren, Ivar Hamberg, Dimitri Olofsson, Karin Andersson
  • Method relating to the manufacture of a semiconductor component
    Patent number: 6140194
    Abstract: A manufacturing method for semiconductor components is disclosed which will allow better precision in the definition of the doped areas of the components and the separation of differently doped areas. A selectively shaped area of, for example, polysilicon, defining the area or areas to be doped, is deposited on the component before masks are applied. This makes the positioning of masks less critical because they only have to be positioned within the area of the polysilicon layer. In this way, an accuracy of 0.1 .mu.m or better can be achieved.
