  • Publication number: 20160268137
    Abstract: A method of fabricating an electrostatic discharge protection structure includes the following steps. Firstly, a semiconductor substrate is provided. Plural isolation structures, a well region, a first conductive region and a second conductive region are formed in the semiconductor substrate. The well region contains first type conducting carriers. The first conductive region and the second conductive region contain second type conducting carriers. Then, a mask layer is formed on the surface of the semiconductor substrate, wherein a part of the first conductive region is exposed. Then, a first implantation process is performed to implant the second type conducting carriers into the well region by using the mask layer as an implantation mask, so that a portion of the first type conducting carriers of the well region is electrically neutralized and a first doped region is formed under the exposed part of the first conductive region.

    Abstract: An electronic device includes a display unit, a touch-sensing module and a processing unit. The display unit displays a user interface. The user interface includes a first seek bar and a second seek bar. The touch-sensing module senses a first dragging event and a second dragging event of the first seek bar, and a third dragging event of the second seek bar corresponding to a touching object. The processing unit implements the user interface. Furthermore, the first seek bar is disabled and the second seek bar is enabled by the processing unit according to a first distance of the first dragging event and a second distance of the second dragging event when the touching object remains in a predetermined area for a predetermined period. The file is enabled according to the final position of the third dragging event.
