    摘要： PROBLEM TO BE SOLVED: To provide a technology capable of improving frequency characteristics without damaging assembling workability in a light-receiving module. SOLUTION: A base of a light-receiving module includes a stepped part connecting a lower-stage surface, a rising surface and an upper-stage surface in this order, and a width of a top face is shorter than that of an underside and film wiring for a reference voltage arranged extensively over the top face and a front and wiring for a signal voltage are positioned in a carrier disposing a photo-detector. The carrier is arranged along the lower-stage surface and the rising surface and a preamplifier is disposed on the upper-stage surface. COPYRIGHT: (C)2011,JPO&INPIT

    摘要： PROBLEM TO BE SOLVED: To provide an electronic device more reducing an inductance of wiring for grounding a semiconductor element than ever. SOLUTION: The device includes the semiconductor element 10, and a grounding table 14 connected with the semiconductor element 10 via the wiring to ground the semiconductor element 10. The grounding table 14 has a height with which a difference between a value of the length of the wiring connecting the semiconductor element 10 with the grounding table 14 and a threshold value is held in a predetermined range.
