  • Method for producing defined polycrystalline silicon areas in an amorphous silicon layer
    Patent number: 7012026
    Abstract: A method of producing well-defined polycrystalline silicon regions is described, in particular for producing electrically conducting regions, in which a substrate is provided with an insulating layer and a layer of doped amorphous silicon, electromagnetic irradiation is performed using a laser source to produce the electrically conducting regions, and a shadow mask is positioned between the laser source and the substrate having the layer for definition of the contours of the electrically conducting regions.

  • Planar trimming resistor, applications and method for its manufacture
    Patent number: 6667683
    Abstract: A trimming resistor is manufactured by depositing a resistive layer on a substrate, with a passivation layer having windows, and a contact layer which is in contact with the resistive layer via the windows. Trimming is carried out by interrupting the contact layer at narrow spots or regions. This invention has application for the manufacture of high-pressure sensors.
