Abstract
The semiconductor device comprises a substrate (1) of semiconductor material with a front side (4) and an opposite rear side (7), a wiring layer (5) at the front side (4), a further wiring layer (8) at the rear side (7), and a through-substrate via (3) connecting the wiring layer (5) and the further wiring layer (8). A hot plate (24) is arranged on or in the substrate, and a sensor layer (21) is arranged in the vicinity of the hot plate. A mold compound (14) is arranged on the rear side (7) above the substrate (1), a cavity (17) is formed in the mold compound (14) to accommodate the sensor layer (21), and the cavity (17) is covered with a membrane (15).
