    Abstract: A wiring board has a structure where multiple wiring layers are stacked one on top of another with insulating layers interposed therebetween. A sheet-shaped member is buried in an outermost insulating layer located on a side of the structure opposite to a side on which a semiconductor element is to be mounted. The sheet-shaped member has a modulus of elasticity and a coefficient of thermal expansion which are similar to a modulus of elasticity and a coefficient of thermal expansion of the semiconductor element. The sheet-shaped member is made of a material having a modulus of elasticity and a coefficient of thermal expansion which are enough to bring respective distributions thereof into a substantially symmetric form in a direction orthogonal to a surface of the wiring board in the case where the semiconductor element is mounted.

  • Patent number: 8803269
    Abstract: A wafer scale implementation of an opto-electronic transceiver assembly process utilizes a silicon wafer as an optical reference plane and platform upon which all necessary optical and electronic components are simultaneously assembled for a plurality of separate transceiver modules. In particular, a silicon wafer is utilized as a “platform” (interposer) upon which all of the components for a multiple number of transceiver modules are mounted or integrated, with the top surface of the silicon interposer used as a reference plane for defining the optical signal path between separate optical components. Indeed, by using a single silicon wafer as the platform for a large number of separate transceiver modules, one is able to use a wafer scale assembly process, as well as optical alignment and testing of these modules.
