    摘要: An image processing apparatus is provided. A splitting unit of the image processing apparatus may split a first space within an input three-dimensional (3D) model into a plurality of subspaces in order to generate an acceleration structure of the input 3D model. A decision unit of the image processing apparatus may set a subspace determined as having a relatively high probability of including a ray progress path among the plurality of subspaces, as a child node having a relatively high traversal priority in the acceleration structure among a plurality of child nodes.

    摘要: An image rendering apparatus may include a buffer memory unit and a processor. The buffer memory unit may store input ray data for image rendering according to a ray tracing scheme while shape data corresponding to the input ray data is being fetched from a cache. The processor may output the received shape data together with the input ray data to an operation apparatus.

    摘要: A sub-word line driver includes a substrate, a plurality of gate lines and at least one gate tab. The substrate includes a plurality of isolation areas and a plurality of active areas, where the two active areas are separated by each isolation area, and the isolation areas and the active areas are extended in a first direction and are arranged in a second direction perpendicular to the first direction. The plurality of gate lines are formed on the substrate, where the gate lines are extended in a second direction and are arranged in the first direction. The at least one gate tab is formed on the substrate, where the at least one gate tab is extended in the first direction to cover the isolation area. Incorrect operation of the sub-word line driver may be prevented, and a power consumption of the sub-word line driver may be reduced.

    摘要: A technology is capable of simplifying a process of manufacturing an asymmetric device in forming a Tunneling Field Effect Transistor (TFET) structure. A method for manufacturing a semiconductor device comprises forming a conductive pattern over a semiconductor substrate, implanting impurity ions with the conductive pattern as a mask to form a first junction region in the semiconductor substrate, forming a first insulating film planarized with the conductive pattern over the first junction region, etching the top of the conductive pattern to expose a sidewall of the first insulating film, forming a spacer at the sidewall of the first insulating film disposed over the conductive pattern, etching the conductive pattern with the spacer as an etching mask to form a gate pattern, and forming a second junction region in the semiconductor substrate with the gate pattern as a mask.
