ABSTRACT:
In a method for manufacturing a semiconductor component having a semiconductor substrate, a flat, porous diaphragm layer and a cavity underneath the porous diaphragm layer are produced to form unsupported structures for a component. In a first approach, the semiconductor substrate may receive a doping in the diaphragm region that is different from that of the cavity. This permits different pore sizes and/or porosities to be produced, which is used in producing the cavity for improved etching gas transport. Also, mesopores may be produced in the diaphragm region and nanopores may be produced as an auxiliary structure in what is to become the cavity region.
