  • Patent number: 11374128
    Abstract: A method includes providing a structure having a substrate and a fin. The fin has first and second layers of first and second different semiconductor materials. The first layers and the second layers are alternately stacked over the substrate. The structure further has a sacrificial gate stack engaging a channel region of the fin and gate spacers on sidewalls of the sacrificial gate stack. The method further includes etching a source/drain (S/D) region of the fin, resulting in an S/D trench; partially recessing the second layers exposed in the S/D trench, resulting in a gap between two adjacent layers of the first layers; and depositing a dielectric layer over surfaces of the gate spacers, the first layers, and the second layers. The dielectric layer partially fills the gap, leaving a void sandwiched between the dielectric layer on the two adjacent layers of the first layers.

    Abstract: A positioning method for obtaining position where a light pen is in contact with a display device at a to-be-positioned spot is provided. The display device includes display areas, corresponding with positioning coding patterns of a built-in positioning frame. The positioning method includes the following steps. Firstly, a positive positioning frame and a negative positioning frame are obtained according to the built-in positioning frame. Next, the positive and the negative positioning frames are respectively added on first original video frames to respectively generate first frame displayed in first frame time and second frame displayed in second frame time. Then the light pen obtains first selected image and second selected image from the first and the second frames respectively. After that, a to-be-positioned pattern is obtained by subtracting the second selected image from the first selected image and a coordinate position of the to-be-positioned spot is obtained.
