<p>PURPOSE:To miniaturize the device by laminating a photoelectric converter element on a longitudinal MOSFET through an insulating film, and forming the longitudinal MOSFET on a single semiconductor substrate so as to also use the substrate as a drain. CONSTITUTION:A light emitting section 4 and an optical detector section are disposed in opposition in the vicinities of the tip ends of lead frames 2, 3. Resin 6 is disposed between the light emitting section 4 and the optical detector section 5, the resin being capable of transmission of light emitted from the light emitting section 4. A longitudinal MOSFETs 8, 9 where photodiode arrays are laminated through insulating films are formed on the same semiconductor substrate 10. These FETs are connected to each other by using in common the substrate 10 as a drain.</p> |
