Abstract
To provide an excellent image by reducing buckling of a CCD device having one-dimensional CCD elements mounted thereon due to changes in temperature. A resin molded semiconductor device including a heat sink having a support face with a semiconductor chip mounted thereon electrically connected to a lead frame, a resin molded case forms a space for accommodating the semiconductor chip therein, and has an opening on an upper face thereof defined by side walls including a plurality of linearly arrayed resin projections above a top surface portion of the side walls, and molds the lead frame and heat sink, and a glass cap closing the opening and secured to the resin molded case by a bonding agent layer. The case has a thermal coefficient of expansion matched with that of the heat sink, and mechanical stress between the case and the cap is absorbed by the bonding agent layer having a thickness greater that the height of the linearly arrayed resin projections above the top surface portion of the side walls.
