  • Patent number: 7910997
    Abstract: A method of manufacturing transistors of a first and second type on a substrate includes producing doped semiconductor areas with a first conductivity type in eventual contact areas of a first type of transistors, depositing a first intrinsic semiconductor layer over an entire surface, activating dopants in the semiconductor areas such that a contact area with the first conductivity type is produced in the intrinsic semiconductor layer, depositing a gate dielectric, producing a gate electrode by depositing a first conductive layer and patterning the first conductive layer, performing ion doping with dopants to produce contact areas with a second conductivity type for a second type of transistor, depositing a passivation layer, opening contact openings, and depositing and patterning a second conductive layer.
    Type: Grant
