Resin molding type semiconductor device and metallic pattern for making mold

摘要

To provide an excellent image by reducing buckling of a CCD device having one-dimensional CCD elements mounted thereon due to changes in temperature. Blackening treated iron or iron-based alloy is used as a material of a heat sink 11 having a one-dimensional CCD element 14 mounted thereon. The thermal coefficient of expansion of the heat sink 21 is matched with that of a hollow molded case 12 for integrally molding the heat sink 11 and a lead frame 20 . A plurality of projections 21 formed on the side of the hollow molded case 12 are disposed at a bonding interface between the glass cap 13 which closes an upper opening of the hollow molded case 12 and side walls of hollow molded case 12.
