  • Publication number: 20200105764
    Abstract: A method of forming a layout definition of a semiconductor device includes the following steps. Firstly, a plurality of first patterns is established to form a material layer over a substrate, with the first patterns being regularly arranged in a plurality of columns along a first direction to form an array arrangement. Next, a plurality of second patterns is established to surround the first patterns. Then, a third pattern is established to form a blocking layer on the material layer, with the third pattern being overlapped with a portion of the second patterns and with at least one of the second patterns being partially exposed from the third pattern. Finally, the first patterns are used to form a plurality of first openings in a stacked structure on the substrate to expose a portion of the substrate respectively.

  • Patent number: 8808015
    Abstract: An exemplary electronic device includes a front wall and a protecting member. The font wall includes a socket used to engagingly receive a plug and a fixing member used to fix the front wall to a side wall associated with the electronic device. The protecting member is located between the socket and the fixing member and slidably attached to the front wall to selectively shield at least part of the socket or shield the fixing member. When the protecting member shields at least part of the socket, the fixing member is exposed to allow the front wall to be disassembled from the side wall. When the protecting member shields the fixing member, the socket is entirely exposed to allow the plug to be inserted into the socket.
