  • METHOD FOR PRODUCING SEMI-CONDUCTING DEVICES AND DEVICES OBTAINED WITH THIS METHOD
    Publication number: 20090127673
    Abstract: A semi-conducting device has at least one layer doped with a doping agent and a layer of another type deposited on the doped layer in a single reaction chamber. An operation for avoiding the contamination of the other layer by the doping agent separates the steps of depositing each of the layers.
    Type: Application
    Filed: January 28, 2009
    Publication date: May 21, 2009
    Applicant: OERLIKON TRADING AG, TRUEBBACH
    Inventors: Ulrich Kroll, Cedric Bucher, Jacques Schmitt, Markus Poppeller, Christoph Hollenstein, Juliette Ballutaud, Alan Howling
