    摘要： Provided are methods of forming semiconductor devices. A method may include preparing a semiconductor substrate including a first region and a second region adjacent the first region. The method may also include forming sacrificial pattern covering the second region and exposing the first region. The method may further include forming a capping layer including a faceted sidewall on the first region using selective epitaxial growth (SEG). The faceted sidewall may be separate from the sacrificial pattern. The sacrificial pattern may be removed. Impurity ions may be implanted into the semiconductor substrate.

    摘要： A display apparatus and a control method thereof are disclosed. The display apparatus includes a signal processor which processes a video signal; a display which displays an image based on the video signal processed by the signal processor, a light source providing light for displaying the image; and a driving circuit which drives the light source on the basis of a dimming signal having an on-section and an off-section for dimming the light source. The driving circuit includes a protection circuit for performing a protection operation as a result of an abnormal electric current flowing in the light source during the off-section. The display apparatus is protected when a short circuit occurs between the light source and the driving circuit, thereby enhancing the stability and reliability of the apparatus.
