<p>PURPOSE:To sufficiently secure a wiring space of leads by partly covering the intermediate part of an inner part of the lead with a silver-plated film, and bonding one end of the wire to the film. CONSTITUTION:The upper surface of the end of each inner part 9a is partly covered with a silver-plated film 10a to improve bondability of wire bonding, and the intermediate part of a shared inner lead 9c is also partly covered with a silver-plated film 10b. First and second pellets 11, 12 are disposed adjacently on both tabs 6A, 6B, bonded by adhesive material layer 14, and electrode pads of the pellets 6A, 6B are wire bonded to the inner parts 9a, 19c of a lead 9 at a unit lead 2.</p> |
