  • Multi-layer dielectric refill for profile control in semiconductor devices
    Patent number: 11996472
    Abstract: A semiconductor device and method of fabricating a semiconductor device involves formation of a trench above a fin (e.g. a fin of a FinFET device) of the semiconductor device and formation of a multi-layer dielectric structure within the trench. The profile of the multi-layer dielectric structure can be controlled depending on the application to reduce shadowing effects and reduce cut failure risk, among other possible benefits. The multi-layer dielectric structure can include two layers, three layers, or any number of layers and can have a stepped profile, a linear profile, or any other type of profile.

  • Laser repair structure of liquid crystal display device and method thereof
    Patent number: 7053977
    Abstract: A laser repair structure of a LCD device obtained by extending dummy metal patterns of the LCD device is used to solve an abnormal color display. The structure includes a first electrical repair layer extending form a dummy metal to a first laser repair location; a second electrical repair layer extending form the dummy metal to a second laser repair location; a third electrical repair layer extending form a first source/drain electrode to the first laser repair location, a first dielectric layer provided between the third electrical repair layer and the first electrical repair layer; and a fourth electrical repair layer extending form a second source/drain electrode to the second laser repair location, the dielectric layer being also provided between the fourth electrical repair layer and the second electrical repair layer.
