Abstract:
The invention relates to a method for the parallel production of an MOS transistor in an MOS area of a substrate (1) and a bipolar transistor in a bipolar area of said substrate (1). The method comprises the creation of an MOS preconditioning structure in the MOS area, whereby the MOS preconditioning structure contains a region (13) provided for a channel, a gate dielectric (14), a gate electrode layer (15, 19) and a masking layer (21a, 21b, 22) on the gate electrode layer (15, 19). In addition, a bipolar preconditioning structure is created in the bipolar area, said structure comprising a conductive layer (20) and a masking layer (21a, 21b, 22) on the conductive layer (20). To establish a gate electrode and a base connection region, the gate electrode layer (15, 19) and the conductive layer (20) are jointly structured. The invention also relates to the simultaneous creation of isolating spacer layers (30, 31) on lateral walls of the gate electrode layer in the MOS area and on the conductive layer in the bipolar area by the application of a first (30) and second spacer layer (31). The isolating spacer layers define the regions to be doped in the MOS area and isolate a base region and an emitter region in the bipolar area. Finally, the first spacer layer (30) and the second spacer layer (31) are selectively etched in the MOS and bipolar areas.
