Abstract:
1. A sensor module, comprising: a carrier; a semiconductor chip comprising a first recess and a second recess in a main surface of the semiconductor chip, a portion of the main surface of the semiconductor chip extending between the first recess and the second recess, sidewalls of the first recess being perpendicular to the main surface of the semiconductor chip; a further semiconductor chip mounted to the carrier, the further semiconductor chip to process electrical signals received from the semiconductor chip; and a housing attached to the carrier, the housing comprising a ceiling wall and side walls connected to the ceiling wall and to the carrier, the ceiling wall comprising a through-hole; wherein the semiconductor chip is mounted to the carrier such that the first recess forms a first cavity with the carrier and the second recess forms a second cavity with the carrier; wherein the first cavity is in fluid connection with the second cavity via a recess formed in the carrier; and wherein the recess formed in the carrier extends between the first cavity and the second cavity directly opposite to the portion of the main surface of the semiconductor chip that extends between the first recess and the second recess.
