  • Patent number: 8395218
    Abstract: The gate-all-around (GAA) type semiconductor device may include source/drain layers, a nanowire channel, a gate electrode and an insulation layer pattern. The source/drain layers may be disposed at a distance in a first direction on a semiconductor substrate. The nanowire channel may connect the source/drain layers. The gate electrode may extend in a second direction substantially perpendicular to the first direction. The gate electrode may have a height in a third direction substantially perpendicular to the first and second directions and may partially surround the nanowire channel. The insulation layer pattern may be formed between and around the source/drain layers on the semiconductor substrate and may cover the nanowire channel and a portion of the gate electrode. Thus, a size of the gate electrode may be reduced, and/or a gate induced drain leakage (GIDL) and/or a gate leakage current may be reduced.

  • Publication number: 20130004623
    Abstract: Provided are a method of producing a waxy rice cake that is not hardened for shelf-life, including: (a) immersing waxy rice in water and removing the water therefrom; (b) first steaming the waxy rice from which water is removed; (c) adding salt and water to the first steamed waxy rice, followed by second steaming; and (d) cooling the second steamed waxy rice and adding flour thereto, followed by punching, a waxy rice cake produced by using the method, and a processed food produced by processing the waxy rice cake. The waxy rice cake has longer storage duration than a conventional waxy rice cake and due to the long storage duration, the waxy rice cake can be distributed for shelf-life according to storage conditions. Also, the waxy rice cake retains its chewy texture and thus is suitable for consumers' tastes.
