  • Semiconductor device
    Patent number: 7382000
    Abstract: A semiconductor device is provided which comprises a connecting lead 4 mounted between a MOS-FET 1 and a regulatory IC 2 on a support plate 3. Connecting lead 4 has a thermally radiative and electrically conductive substrate 6 and electrically insulative and thermal transfer-resistive covering 7. Substrate 6 has one end 6a providing one main surface 4a of connecting lead 4 which is mounted and electrically connected on the other main surface 1b of MOS-FET 1. Covering 7 provides the other main surface 4b of connecting lead 4 for supporting regulatory IC 2 at one end 6a of substrate 6.
    Type: Grant
