    Abstract: A bonding pad structure for a semiconductor device includes a first lower metal layer beneath a second upper metal layer in a bonding region of the device. The lower metal layer is formed such that the metal of the lower metal layer is absent from the bonding region. As a result, if damage occurs to the structure during procedures such as probing or bonding at the bonding region, the lower metal is not exposed to the environment. Oxidation of the lower metal layer by exposure to the environment is prevented, thus improving reliability of the device.

  • Patent number: 6926955
    Abstract: According to one aspect of the invention, a structure and method for providing improved thermal conductivity of a thermal interface material (TIM) made of phase changed polymer matrix and a fusible filler material is disclosed. The TIM may also have a non-fusible filler material and a percentage of a non-phase change polymer added to the phase change polymer matrix. The TIM, used to mate and conduct heat between two or more components, can be highly filled systems in a polymeric matrix where the fillers are thermally more conductive than the polymer matrix.

  • Patent number: 6921583
    Abstract: With an Al—Cu bonded structure, an Ag layer can be remained at the Al—Cu bonding interlayer providing ductile deformation behavior and a tensile strength at the bonded interlayer similar to that of the Al base material. This results in superior bonding characteristics. Furthermore, a thin Al—Cu bonded structure can be obtained as a result of using the Al—Cu dissimilar material bonded section, which has superior workability, as the base material to perform rolling for wall-thickness reduction. The thin Al—Cu structure has superior dimensional accuracy and can meet diverse dimensional demands. The structure combines the light weight of Al with its particular heat transfer and heat dissipative characteristics and anti-corrosive properties of Cu, allowing it to meet the compact, thin, light-weight, and high-performance needs of electronic devices. The structure can be widely used in heat exchanges and heat transfer devices.

  • Patent number: 6884511
    Abstract: Ceramic-containing bodies can be bonded to other ceramic-containing bodies, or to metals or metal-containing bodies, by way of an aluminum-silicon brazing alloy. Such alloys feature high thermal conductivity and a melting range intermediate to Cu—Sil and Au—Si. By depositing a layer of silicon or aluminum, e.g., by vapor deposition, onto a surface of the ceramic-containing body, the formation of deleterious intermetallic phases at the brazing interface is avoided. This technique is particularly useful for joining reaction-bonded silicon carbide (RBSC) composite bodies, and particularly such composite bodies that contain appreciable amounts of aluminum as a metallurgical modification of the residual silicon phase. When the RBSC body contains minor amounts of the aluminum alloying constituent, or none, the metallization layer is not required. The resulting bonded structures have utility as mirrors, as packaging for electronics, and in semiconductor lithography equipment, e.g.

  • Patent number: 6875330
    Abstract: A process is provided for coating metallic workpieces with a bearing material, wherein the workpiece first receives a hard chromium plating having a pearl or columnar structure type surface. A predominantly silver layer is then galvanically deposited, which fills in and smooths the pearl or columnar structure type surface of the hard chromium plating. Optionally, additional hard chromium platings and predominantly silver-containing layers may be applied, preferably galvanically. The predominantly silver layer may advantageously contain a graphite component.

  • Patent number: 6852210
    Abstract: To provide a plating method, which enables wide industrial use of the redox system electroless plating method having excellent characteristics, and a plating bath precursor which is preferable for the plating method. The plating method comprises a process oxidizing first metal ions of a redox system of a plating bath from a lower oxidation state to a high oxidation state, and second metal ions of said redox system are reduced and deposited onto the surface of an object to be plated, wherein a process is provided in which by supplying the electrical current to the plating bath, the first metal ions are reduced from said lower oxidation state to thereby activate the plating bath. The plating bath precursor is formed stabilizing the plating bath so that reduction and deposition of the second metal ions substantially do not occur in order to improve its storing performance.
