    Abstract: A flip chip package includes a substrate and a semiconductor chip. The substrate includes a substrate body, a metal wiring having a terminal part some of which is disposed in the substrate body, a solder resist pattern formed on the substrate body with an opening for exposing the terminal part, and an organic anti-oxidation layer for covering the terminal part. The semiconductor chip has a bump formed through (e.g., penetrates) the organic anti-oxidation layer and is electrically connected to the terminal part. The present invention prevents oxidation of the terminal part and allows easy coupling of a bump of a semiconductor chip and the terminal part of the substrate, since an anti-oxidation layer including an organic matter is formed over a surface of a terminal part including copper which is easily oxidized.

  • Publication number: 20100230813
    Abstract: The invention includes methods of forming layers conformally over undulating surface topographies associated with semiconductor substrates. The undulating surface topographies can first be exposed to one or more of titanium oxide, neodymium oxide, yttrium oxide, zirconium oxide and vanadium oxide to treat the surfaces, and can be subsequently exposed to a material that forms a layer conformally along the treated surfaces. The material can, for example, comprise one or both of aluminum silane and aluminum silazane. The invention also includes semiconductor constructions having conformal layers formed over liners containing one or more of titanium oxide, yttrium oxide, zirconium oxide and vanadium oxide.

  • Patent number: 7795730
    Abstract: The invention includes a first step for forming a first conductive layer composed of a high melting point metal to be in contact with an insulating layer; and a second step for forming a second conductive layer by discharging a composition containing a conductive material so as to be in contact with the first conductive layer. The first conductive layer is formed prior to forming the second conductive layer by droplet discharging, and hence, adhesiveness and peel resistance of the second conductive layer are improved. Furthermore, the insulating layer is covered with the first conductive layer, thereby preventing damage or destruction of the insulating layer.
