CONVERTER MODULE AND METHOD FOR MANUFACTURING SAME

摘要

Provided is a converter module which can suppress entry of cutting water and cutting dusts when the module is divided into pieces and has improved reliability. The converter module is provided with: a substrate (6); one or more semiconductor elements (4) mounted on the first main surface of the substrate (6); a cap (1) which is affixed on the first main surface of the substrate (6) and covers the semiconductor element(s) (4); a through hole (8) formed in the substrate (6) or the cap (1); and a plurality of electrodes (7) which are formed on the second main surface, i.e., the surface on the reverse side of the first main surface of the substrate. The through hole (8) has a shape which suppresses entry of water from the outside.
