Abstract:
A method for manufacturing a semiconductor device comprises: forming a circuit pattern and a first metal film on a first major surface of a body wafer; forming a through-hole penetrating the body wafer from a second major surface of the body wafer and reaching the first metal film; forming a second metal film on a part of the second major surface of the body wafer, on an inner wall of the through-hole, and on the first metal film exposed in the through-hole; forming a recess on a first major surface of a lid wafer; forming a third metal film on the first major surface of the lid wafer including inside the recess of the lid wafer; with the recess facing the circuit pattern, and the first metal film contacting the third metal film, joining the lid wafer to the body wafer; and dicing the joined body wafer and lid wafer along the through-hole.
