  • Semiconductor device and method for fabricating the same
    Patent number: 11957064
    Abstract: A semiconductor device includes a magnetic tunneling junction (MTJ) on a substrate, a spacer adjacent to the MTJ, a liner adjacent to the spacer, and a first metal interconnection on the MTJ. Preferably, the first metal interconnection includes protrusions adjacent to two sides of the MTJ and a bottom surface of the protrusions contact the liner directly.
    Type: Grant

  • Cob module of an optical mouse
    Patent number: 8952896
    Abstract: A COB module of an optical mouse has a controller circuit and optical components of the optical mouse integrated thereon, so as to improve the problem with conventional optical mice that light path shifting tends to occur and improve the imaging definition. By disposing a button and wheel mechanism independently outside the COB module, the optical mouse has significantly improved flexibility in design, lower cost related to design alteration, and relaxed requirements on alignment and correction during production.

  • OPTICAL MOUSE
    Publication number: 20100090956
    Abstract: Well-designed absolutely fixing mechanisms are provided for optical mice to avoid loose engagement between the optical components and base plate in an optical mouse, and eliminate shifting and out-of-focus of the light path in the optical mouse, thereby improving performance of the optical mouse.

  • Method of fabricating a ferroelectric capacitor and a ferroelectric capacitor produced by the method
    Publication number: 20040145002
    Abstract: A method is described for fabricating a ferroelectric capacitor that overlies a metal-oxide-semiconductor transistor. Low temperature processes are employed to deposit a conducting layer and a ferroelectric layer on an insulating layer that separates the transistor from the ferroelectric capacitor.
