  • Publication number: 20140027760
    Abstract: A semiconductor device and manufacturing method thereof are provided. The manufacturing method of the semiconductor device includes sequentially forming a gate electrode, a gate insulating layer, an oxide semiconductor layer and an etching stop layer on a substrate. The etching stop layer has two contact openings exposing a portion of the oxide semiconductor layer. A metal layer is formed on the etching stop layer, and connected with the oxide semiconductor layer via the contact openings. A half-tone patterned photoresist layer is formed on the metal layer, and is taken as an etching mask to remove the metal layer and the etching stop layer. A thickness of the half-tone patterned photoresist layer is reduced until a second portion of the half-tone patterned photoresist layer is removed, such that a patterned photoresist layer is formed as an etching mask for removing the metal layer and the oxide semiconductor layer.

  • Patent number: 7807551
    Abstract: In a method for fabricating a flexible pixel array substrate, first, a release layer is formed on a rigid substrate. Next, on the release layer, a polymer film is formed, the adhesive strength between the rigid substrate and the release layer being higher than that between the release layer and the polymer film. The polymer film is formed by spin coating a polymer monomer and performing a curing process to form a polymer layer. Afterwards, a pixel array is formed on the polymer film. The polymer film with the pixel array formed thereon is separated from the rigid substrate.

    Abstract: A system and method for adjusting optical drives. Rotating disc datum, and leader pin datum, must be adjusted to a specific position during a packaging process. An autocollimator according to the present invention senses tilt and sway of the rotating disc, outputting a first bright spot through a switch box to a monitor. In addition, an optimum tilt angle of the optical pickup head is obtained by a reader through calculation by a host, outputting a second bright spot through the switch box to the monitor. Therefore, the first bright is coincided with the second bright spot by a adjustment mechanism and according to picture switch by the switch box, reading optimum tilt angle adjustment. Furthermore, individual tilt angle of each optical pickup head is calculated by a host for satisfying adjustment of different tilt angles with different optical paths in reading CD and DVD discs.
