Abstract: A semiconductor device includes a semiconductor layer. A gate structure is disposed over the semiconductor layer. A spacer is disposed on a sidewall of the gate structure. A height of the spacer is greater than a height of the gate structure. A liner is disposed on the gate structure and on the spacer. The spacer and the liner have different material compositions.

Abstract: Examples of an integrated circuit with gate cut features and a method for forming the integrated circuit are provided herein. In some examples, a workpiece is received that includes a substrate and a plurality of fins extending from the substrate. A first layer is formed on a side surface of each of the plurality of fins such that a trench bounded by the first layer extends between the plurality of fins. A cut feature is formed in the trench. A first gate structure is formed on a first fin of the plurality of fins, and a second gate structure is formed on a second fin of the plurality of fins such that the cut feature is disposed between the first gate structure and the second gate structure.

Abstract: A light deflection film and a display device using the same are provided. The display device includes a display panel and a light deflection film. The light deflection film is disposed on the display panel and includes a first layer, a second layer and a light deflection structure formed at an interface between the first layer and the second layer. The first layer has a first refractive index. The second layer is formed on the first layer and has a second refractive index. The first layer of the light deflection film is located between the second layer and the display panel, and the first refractive index is larger than the second refractive index.

Abstract: The invention relates to an optical element disposed on a light source. The optical element includes a first medium, a second medium and a light deflecting structure. The second medium is formed on the first medium. The light deflecting structure is formed on the interface between the first medium and the second medium. The relationship between the optical element and the light emitted by the light source satisfies the formula: 0<|WB?WA|/Wref<10, wherein WA is an image broadening width obtained under the circumstances of the light passing through the optical element with the first medium as the light incident side; WB is an image broadening width obtained under the circumstances of the light passing through the optical element with the second medium as the light incident side; and Wref is a width obtained under the circumstances of the light not passing through the optical element.
