  • Patent number: 8345435
    Abstract: A conductor having a projecting portion is formed which forms a terminal portion. An uncured prepreg including a reinforcing material is closely attached to the conductor and the prepreg is cured to form an insulating film including the reinforcing material. When the prepreg is closely attached, the prepreg is stretched by the projecting portion, so that a region of the prepreg, which is closely attached to the conductor, can be thinner than the other region of the prepreg. Then, by reducing the thickness of the entire insulating film, an opening can be formed in the portion having a smaller thickness. The step of reducing the thickness can be performed by etching. Further, it is preferable not to remove the reinforcing material in this step. The strength of a terminal and an electronic device can be increased by leaving the reinforcing material at the opening.

    Abstract: This application describes a method of forming a switching device. The method includes forming a first dielectric material overlying a surface region of a substrate. A bottom wiring material is formed overlying the first dielectric material and a switching material is deposited overlying the bottom wiring material. The bottom wiring material and the switching material is subjected to a first patterning and etching process to form a first structure having a top surface region and a side region. The first structure includes at least a bottom wiring structure and a switching element having a top surface region including an exposed region of the switching element. A second dielectric material is formed overlying at least the first structure including the exposed region of the switching element. The method forms a first opening region in a portion of the second dielectric layer to expose a portion of the top surface region of the switching element.
