    Abstract: Charge-encoded chiplets are produced using a sacrificial metal mask and associated fabrication techniques and materials that are compatible with typical semiconductor fabrication processes to provide each chiplet with two different (i.e., positive and negative) charge polarity regions generated by associated patterned charge-inducing material structures. A first charge-inducing material having a positive charge polarity is formed on a silicon wafer over previously-fabricated integrated circuits, then a sacrificial metal mask is patterned only over a portion of the charge-inducing material structure, and a second charge-inducing material structure (e.g., a self-assembling octadecyltrichlorosilane monolayer) is deposited having a negative charge polarity. The sacrificial metal mask is then removed to expose the masked portion of the first charge-inducing material structure, thereby providing the chiplet with both a positive charge polarity region and a negative charge polarity region.

    Abstract: A circuit device having superior voltage resistance is provided. A structure is achieved that omits the resin layer that is normally provided to the top surface of a circuit board. Specifically, a ceramic substrate (22) is disposed on the top surface of a circuit board (12) comprising a metal, and a transistor (34) such as an IGBT is mounted to the top surface of the ceramic substrate (22). As a result, the transistor (34) and the circuit board (12) are insulated from each other by the ceramic substrate (22). The ceramic substrate (22), which comprises an inorganic material, has an extremely high voltage resistance compared to the conventionally used insulating layer comprising resin, and so even if a high voltage on the order of 1000V is applied to the transistor (34), short circuiting between the transistor (34) and the circuit board (12) is prevented.

  • Patent number: 8570763
    Abstract: A high quality component-incorporated substrate achieves a sufficient connection between an in-plane electrode and an interlayer connection conductor at low cost. A method of forming a hole for an interlayer connection conductor of a resin substrate includes a step of forming an in-plane electrode in a core substrate, a step of forming a light reflective conductor for reflecting a laser beam applied on the in-plane electrode in a later step, a step of forming a resin layer so as to cover the core substrate, the in-plane electrode and the light reflective conductor, and a step of forming a hole for the interlayer connection conductor by removing the resin layer on the light reflective conductor through the use of a laser beam.

  • Patent number: 8493746
    Abstract: In one embodiment of the present invention, inert nano-sized particles having dimensions from 1 nm to 1,000 nm are added into a solder ball. The inert nano-sized particles may comprise metal oxides, metal nitrides, metal carbides, metal borides, etc. The inert nano-sized particles may be a single compound, or may be a metallic material having a coating of a different material. In another embodiment of the present invention, a small quantity of at least one elemental metal that forms stable high melting intermetallic compound with tin is added to a solder ball. The added at least one elemental metal forms precipitates of intermetallic compounds with tin, which are dispersed as fine particles in the solder.
