  • Patent number: 9029999
    Abstract: A semiconductor sensor device is packaged using a footed lid instead of a pre-molded lead frame. A semiconductor sensor die is attached to a first side of a lead frame. The die is then electrically connected to leads of the lead frame. A gel material is dispensed onto the sensor die. The footed lid is attached to the substrate such that the footed lid covers the sensor die and the electrical connections between the die and the lead frame. A molding compound is then formed over the substrate and the footed lid such that the molding compound covers the substrate, the sensor die and the footed lid.

  • Patent number: 7727819
    Abstract: The present disclosure provides an optical functional device-mounted module which needs no expensive or special members, can be reduced in size, and provide a producing process thereof. A bank to dam a liquid sealing resin is provided on a substrate around an optical functional device, the substrate being formed with a predetermined wiring pattern and having the optical functional device mounted thereon. The liquid sealing resin is filled between the functional device and the bank by dropping the liquid sealing resin therebetween. A package component member having a light transmission hole corresponding to an optical function part of the optical functional device is brought into contact with the bank such that the light transmission hole is opposed to the function part of the optical functional device, thereby causing the package component member to contact with the liquid sealing resin.

  • Patent number: 7723846
    Abstract: A power semiconductor module and a method of manufacture thereof includes a lead frame carrying lead having inner and outer lead portions. The outer lead portions, which are connected by soldering to semiconductor chips simultaneously, eliminate the need for using bonding wires. Since no bonding wire is used for connecting the leads and the semiconductor chips, a sufficient current capacity is obtained. The bonding between an insulating circuit board and the semiconductor chips and the bonding between the semiconductor chips and the leads can be made simultaneously in a single step of reflow-soldering. As a result, the mounting time can be shortened and the power semiconductor module can be manufactured more efficiently.

  • Patent number: 7700958
    Abstract: A light emitting device having a structure in which oxygen and moisture are prevented from reaching light emitting elements, and a method of manufacturing the same, are provided. Further, the light emitting elements are sealed by using a small number of process steps, without enclosing a drying agent. The present invention has a top surface emission structure. A substrate on which the light emitting elements are formed is bonded to a transparent sealing substrate. The structure is one in which a transparent second sealing material covers the entire surface of a pixel region when bonding the two substrates, and a first sealing material (having a higher viscosity than the second sealing material), which contains a gap material (filler, fine particles, or the like) for protecting a gap between the two substrates, surrounds the pixel region. The two substrates are sealed by the first sealing material and the second sealing material.

  • Patent number: 7675186
    Abstract: An IC package mainly includes a substrate having slot(s), a chip, a protective encapsulant, a stiffening encapsulant, and a plurality of external terminals. The Young's modulus of the stiffening encapsulant is greater than the one of the protective encapsulant and the curing shrinkage of the stiffening encapsulant is smaller than the one of the protective encapsulant. The protective encapsulant is formed on one of the surfaces of the substrate for encapsulating the chip. The stiffening encapsulant protrudes from the other surface of the substrate where the external terminals are disposed. Moreover, the stiffening encapsulant is formed inside the slot and is contacted with the chip. Since the stiffening encapsulant is embedded and formed inside the slot, therefore, the contact area of the stiffening encapsulant with the substrate is increased to enhance the warpage resistance of the IC package.

  • Patent number: 7670940
    Abstract: The plating method comprises the step of forming a resin layer 10 over a substrate 16; the step of cutting the surface part of the resin layer 10 with a cutting tool 12; the step of forming a seed layer 36 on the resin layer 10 by electroless plating; and the step of forming a plating film 44 on the seed layer 36 by electroplating. Suitable roughness can be give to the surface of the resin layer 10, whereby the adhesion between the seed layer 36 and the resin layer 10 can be sufficiently ensured. Excessively deep pores are not formed in the surface of the resin layer 10, as are by desmearing treatment, whereby a micronized pattern of a photoresist film 40 can be formed on the resin layer 10. Thus, interconnections 44, etc. can be formed over the resin layer 10 at a narrow pitch with high reliability ensured.
