主权项

1. A semiconductor module, comprising:
a housing having two outer wall sections arranged at opposite outer sides of the housing, a cover extending from one of the outer wall sections to the other one of the outer wall sections, and a first shaft wall arranged between and spaced apart from the outer wall sections, the first shaft wall delimiting a first shaft; a circuit carrier having a top side; a semiconductor chip arranged in the housing and on the top side of the circuit carrier; an electrically conductive first connection element which runs through the first shaft and extends out of the housing; a first potting compound arranged between the circuit carrier and the cover and partly between the first connection element and the first shaft wall and which seals the first shaft in interaction with the first connection element; a second potting compound arranged between the first potting compound and the cover and partly between the first connection element and the first shaft wall and which seals the first shaft in interaction with the first connection element; and at least one gas-filled volume region directly adjoining the first potting compound, wherein the first shaft wall has at a side facing the circuit carrier a lower end dipping into the first potting compound.
