Abstract
A plastic-molded-type semiconductor device is provided wherein two semiconductor chips, having main surfaces on which electrodes and circuits are formed, are arranged to face each other. A lead frame is placed between these two semiconductor chips and electrically connected to their electrodes, and a plastic package is formed by plastic-sealing the above components. To provide for secure and convenient electrical connections between the electrodes on the semiconductor chips and the lead frame, wiring patterns are provided on the main surfaces of the semiconductor chips through the intermediation of insulating films. With this structure, it is possible for two large-sized semiconductor chips having electrodes in their middle sections to be encased in a single, relatively thin package.
