  • Patent number: 8912650
    Abstract: A semiconductor device has a semiconductor die with a first conductive layer formed over the semiconductor die. A first insulating layer is formed over the semiconductor die with a first opening in the first insulating layer disposed over the first conductive layer. A second conductive layer is formed over the first insulating layer and into the first opening over the first conductive layer. An interconnect structure is formed over the first and second conductive layers within openings of a second insulating layer. The second insulating layer is removed. The interconnect structure can be a conductive pillar or conductive pad. A bump material can be formed over the conductive pillar. A protective coating is formed over the conductive pillar or pad to a thickness less than one micrometer to reduce oxidation. The protective coating is formed by immersing the conductive pillar or pad into the bath containing tin or indium.

  • Patent number: 8901734
    Abstract: An interconnect pad is formed over a first substrate. A photoresist layer is formed over the first substrate and interconnect pad. A portion of the photoresist layer is removed to form a channel and expose a perimeter of the interconnect pad while leaving the photoresist layer covering a central area of the interconnect pad. A first conductive material is deposited in the channel of the photoresist layer to form a column of conductive material. The remainder of the photoresist layer is removed. A masking layer is formed around the column of conductive material while exposing the interconnect pad within the column of conductive material. A second conductive material is deposited over the first conductive layer. The second conductive material extends above the column of conductive material. The masking layer is removed. The second conductive material is reflowed to form a column interconnect structure over the semiconductor device.

  • Patent number: 8901725
    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: 8896120
    Abstract: Methods for producing air gap-containing metal-insulator interconnect structures for VLSI and ULSI devices using a photo-patternable low k material as well as the air gap-containing interconnect structure that is formed are disclosed. More particularly, the methods described herein provide interconnect structures built in a photo-patternable low k material in which air gaps of different depths are defined by photolithography in the photo-patternable low k material. In the methods of the present invention, no etch step is required to form the air gaps. Since no etch step is required in forming the air gaps within the photo-patternable low k material, the methods disclosed in this invention provide highly reliable interconnect structures.
