Patent ID: 6998701

Claim:
A resin sealing-type semiconductor device comprising: a lead frame including a first die pad portion, a second die pad portion, and outer leads provided in a manner corresponding to the first and second die pad portions; a first semiconductor chip with a large amount of heat generation, which is die-bonded to the first die pad portion and whose external electrode leading-out bonding pads and the outer leads corresponding thereto are wire-bonded; and a second semiconductor chip smaller in the amount of heat generation than the first semiconductor chip, which is die-bonded to the second die pad portion and whose external electrode leading-out bonding pads and the outer leads corresponding thereto are wire-bonded, wherein the first semiconductor chip is resin-sealed by a high thermal conductive resin, and the second semiconductor chip and the first semiconductor chip resin-sealed by the high thermal conductive resin are integrally resin-sealed by a non-high thermal conductive resin.
