  • Patent number: 8216762
    Abstract: An array for a display device is formed by adhering a positive dry film resist, which has a positive photoresist resin layer over a supporting film, to a substrate such that the photoresist resin layer adheres on a surface of the substrate. The supporting film is then released from the photoresist resin layer adhered to the surface of the substrate, the layer is exposed to light; and the positive type photoresist layer is developed to remove exposed regions.

  • Patent number: 8212311
    Abstract: In a vertical transistor comprising a pillar-shaped semiconductor layer and a gate electrode formed around the pillar-shaped semiconductor layer, it is difficult to form a transistor having a gate length greater than that of the vertical transistor. The present invention provides a semiconductor device which comprises two vertical transistors comprising first and second pillar-shaped semiconductor layers each formed on a first diffusion layer on a substrate. The vertical transistors have a common gate electrode. A first upper diffusion layer formed on a top of the first pillar-shaped semiconductor layer is connected to a source electrode, and a second upper diffusion layer formed on a top of the second pillar-shaped semiconductor layer is connected to a drain electrode. The vertical transistors are connected in series to operate as a composite transistor having a gate length two times greater than that of each of the vertical transistors.
