Patent attributes
A semiconductor device includes a semiconductor layer, a first electrode on a first surface of the semiconductor layer, a plurality of second electrodes on a second surface of the semiconductor layer, a control electrode between the first electrode and each of the plurality of second electrodes and electrically insulated from the semiconductor layer and each of the plurality of second electrodes, and a resin layer partially covering the second surface of the semiconductor layer and having a plurality of openings through which the respective second electrodes are at least partially exposed. Each of the plurality of openings has rounded corners. The device further includes a sensor element above the second surface of the semiconductor layer and covered by a first part of the resin layer surrounded by the openings.
