    摘要: A semiconductor device includes the following: a semiconductor substrate of a first conduction type; an intrinsic semiconductor layer of the first conduction type formed on the semiconductor substrate; a first semiconductor layer of a second conduction type formed on the intrinsic semiconductor layer; a first impurity layer of the first conduction type formed in the first semiconductor layer of the second conduction type; and a bipolar transistor and a MIS transistor formed in the first semiconductor layer of the second conduction type. The laminated structure of the semiconductor substrate, the intrinsic semiconductor layer, and the first semiconductor layer provides a diode for photoelectric conversion. A first insulator layer and a second insulator layer are formed respectively in at least a portion below the bipolar transistor and the MIS transistor. The transistors are isolated from the semiconductor substrate by the insulator layers, so that the characteristics of the transistors can be adjusted independently of the diode.

    摘要: To more precisely output signals of optical recording media, a semiconductor laser element is mounted in a concave portion on the surface of a semiconductor substrate so that the optical axis of signal detecting light emitted from the semiconductor laser element is substantially parallel to the surface of the semiconductor substrate, and the light emitted from the semiconductor laser element is reflected at the side surface of the concave portion that is opposed to the signal detecting light emitting side of the semiconductor laser element in a direction substantially perpendicular to the surface of the semiconductor substrate. A light receiving portion for signal detection is provided in an area outside the concave portion on the surface of the semiconductor substrate where the semiconductor laser element is mounted. When the signal detecting light emitting side of the semiconductor laser element is the front side of the semiconductor laser element, a first light intercepting region is provided in areas posterior to, obliquely posterior to and at the left and right sides of the semiconductor laser element on the bottom surface of the concave portion, and a second light intercepting region is provided on, of the side surfaces of the concave portion, at least the side surface between the semiconductor laser element and the light receiving portion.
