  • Patent number: 8939348
    Abstract: After a microcrystalline layer having a grain size that is finer than that of a base member is formed on the surface of at least one of a first bonding portion and a second bonding portion, the gap between the first bonding portion and the second bonding portion is filled with a solution into which copper oxide can be eluted, so as to deposit copper oxide contained in the surface oxide film into the solution. By applying pressure and by heating at a temperature of at most the copper recrystallization temperature, the components contained in the solution are removed except for copper, so as to elute copper oxide, thereby bonding the first bonding portion and the second bonding portion via the copper thus deposited. Subsequently, the copper is solid-phase diffused into the first bonding portion and the second bonding portion.

  • Publication number: 20140375611
    Abstract: A first resistive film is arranged such that one edge thereof is connected to a first terminal, and an edge that is opposite to the aforementioned edge is connected to a second terminal. A second resistive film is arranged with a gap between it and the first resistive film such that one edge thereof is connected to a third terminal. A voltage generating unit applies a predetermined first bias voltage and a predetermined second bias voltage to the first terminal and the second terminal, respectively. A voltage detection unit detects a panel voltage that occurs at the third terminal. A current detection unit detects a panel current that flows through a path including the first terminal, the first resistive film, and the second terminal. A computation unit determines the coordinates touched by the user, based upon the values of the panel voltage and the panel current.

  • Patent number: 8814029
    Abstract: The gap between first and second bonding portions is filled with a disperse solution obtained by dispersing copper micro-particles into a solution for copper oxide elution, so as to elute copper oxide configured as the outermost layer of the first bonding portion and copper oxide configured as the outermost layer of the second bonding portion, and copper oxide formed on the surface of each copper micro-particle. Pressure is applied to the first and second bonding portions using a press machine so as to raise the pressure of the disperse solution. At the same time, heat is applied under a relatively low temperature condition of 200° C. to 300° C., so as to remove the components contained in the disperse solution except for copper, thereby depositing copper. Thus, a first base portion and a second base portion are bonded via a copper bonded portion containing copper derived from the copper micro-particles.
