    摘要: A photodetector device and a process for manufacturing the same are described. The photodetector device comprises a doped semiconductor substrate; an intrinsic semiconductor material layer formed over the substrate, for absorbing incident light; an upper semiconductor material layer doped with the opposite type to the substrate, formed on a portion of the intrinsic semiconductor material layer to allow at least a portion of the incident light to directly enter the intrinsic semiconductor material layer; an upper electrode formed in a predetermined pattern on the upper semiconductor material layer, the upper electrode electrically connected to the upper semiconductor material layer; and a lower electrode electrically connected to the substrate, wherein a portion of the intrinsic semiconductor material layer constitutes at least a part of a photo-receiving surface. The photodetector device has a photo-receiving surface, which is formed by removing all or a portion of the upper semiconductor material layer within a photo-receiving area, which allows at least a portion of the incident light to directly enter the intrinsic semiconductor material layer, thereby reducing capacitance even with a relatively large photo-receiving surface.

    摘要: A photodetector device includes a doped semiconductor substrate. A first intrinsic semiconductor material layer, a main reflector, a second intrinsic semiconductor material layer, an upper semiconductor material layer, which is doped the opposite as the substrate, are formed in succession on the semiconductor substrate. An upper electrode is formed on and electrically connected with the upper semiconductor layer, and a lower electrode is electrically connected to the semiconductor substrate. One of the intrinsic semiconductor layers is relatively thin to absorb incident light, while the other is relatively thick. The photodetector device, a p-i-n photodetector, has an I region including the intrinsic semiconductor layers with different thicknesses, and a main reflector therebetween. The thickness of the entire I region can be increased with a reduced transit distance for holes. Thus, low driving voltage and high sensitivity to a high frequency optical signal requirements can be realized without reducing the size of the photo-receiving area.

    摘要: An optical bench is provided, as are a thin optical pickup that employs the optical bench, and a method of manufacturing the optical bench. The optical bench includes a light source for generating light for recording and reproducing information to and from an optical disc, a light source stand on which the light source is mounted, a mirror adjacent to the light source stand, and a bottom surface at a lower point than the light source stand and between the light source stand and the mirror surface. Sides of the light source stand besides the side facing the mirror are connected to the surface of the substrate by a flat sloped surface. Along the sloped surface, two electrodes for supplying power to the light source are connected to the light source stand. Since the metal wirings are formed along the sloped surface without trenches or windings between the light source stand and the silicon substrate, no disconnection of metal lines at a corner occurs.
