Abstract:
1. A method of manufacturing transistors of a first and second type on a substrate, comprising the following steps performed in the following sequence: 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.
