Abstract: In a light detection device 1 the plurality of pad electrodes are arranged on the semiconductor substrate. Each of the plurality of wires is connected to the pad electrode corresponding thereto. A stitch bond of a corresponding wire is formed on each pad electrode. A distance between each pad electrode and a cell corresponding to the pad electrode is smaller than a distance between the pad electrodes connected to mutually different cells of the cells. The plurality of pad electrodes are arranged in a first region and a second region that are spaced apart from each other with a light receiving region interposed therebetween. The pad electrode corresponding to a cell is arranged in the first region. The pad electrode corresponding to a cell is arranged in the second region.

Abstract: An electronic component includes a wiring substrate having a first surface, a second surface opposite to the first surface, a side surface connected to the first surface and the second surface, and a groove portion formed in the side surface and extending from the first surface to the second surface. The electronic component further includes a first electrode disposed on the first surface along the first surface, a second electrode disposed on the second surface along the second surface, a connection conductor disposed over an entire inner surface of the groove portion and electrically connected to the first electrode and the second electrode, an electronic element disposed on the first surface and electrically connected to the first electrode, and a resin portion disposed on the first surface. All edges of the second electrode are spaced apart from the side surface.

Abstract: An optical semiconductor device includes a wiring board including a first surface and a second surface, a cover disposed to face the first surface, an optical semiconductor element disposed on the first surface, a plurality of electrodes disposed on the second surface, and a resist layer disposed on the second surface and located at least between the plurality of electrodes. A ventilation hole that penetrates the first surface and the second surface is formed in the wiring board. The second surface includes a disposition region in which the resist layer is disposed and a non-disposition region in which the resist layer is not disposed. The non-disposition region includes a first region in which the ventilation hole is disposed and a second region that reaches an edge of the second surface from the first region.

Abstract: In a light detection device, the semiconductor substrate has first and second main surfaces facing each other. The semiconductor substrate includes a plurality of cells. Each of the plurality of cells includes at least one avalanche photodiode. The plurality of pad electrodes are arranged on the first main surface so as to be spaced apart from the plurality of cells. The plurality of wiring portions are arranged on the first main surface. Each of the plurality of wiring portions connects the cell and the pad electrode corresponding to each other. The semiconductor substrate includes a peripheral carrier absorbing portion configured to absorb carriers located at a periphery of the peripheral carrier absorbing portion. The peripheral carrier absorbing portion is provided around each pad electrode and each wiring portion when viewed from a direction perpendicular to the first main surface.
