Abstract: The present invention relates to an image encoding method and an image decoding method. The image decoding method includes partitioning a picture into a plurality of coding units, constructing a coding unit group including at least one coding unit of the plurality of coding units, obtaining coding information in units of one coding unit group, and decoding at least one coding unit of the plurality of coding units included in the coding unit group by using the obtained coding information.

Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In video encoding and decoding, multiple partition blocks are generated by splitting a target block. A prediction mode is derived for at least a part of the multiple partition blocks, among the multiple partition blocks, and prediction is performed on the multiple partition blocks based on the derived prediction mode. When prediction is performed on the partition blocks, information related to the target block may be used, and information related to an additional partition block, which is predicted prior to the partition block, may be used.

Abstract: A semiconductor manufacturing apparatus for rinsing a wafer after chemically treating the wafer includes a spin chuck for holding the wafer, a first supply nozzle located above the spin chuck and a second nozzle connected to a lower end of the spin chuck. First and second chemical fluid supply pipes are connected at one end to a chemical fluid supply and at the other end to respective ends of the first and second supply nozzles. First and second deionized water supply pipes are connected at one end to a deionized water supply and at the other end to respective ends of the first and second supply nozzles. A hydrophilic-making fluid supply pipe is connected at one end to hydrophilic-making fluid supply and at the other end to the end of the first supply nozzle. It is thus possible to prevent the generation of watermarks at the boundary between hydrophobic material and hydrophilic material by performing a rinsing operation after changing the hydrophobic material into hydrophilic material.

Abstract: A method of stripping a nitride layer from a wafer includes the steps of putting the wafer into a process bath containing a stripping solution, passing the stripping solution from the process bath through a filter to remove the nitride particles contained therein, heating the filtered stripping solution through an in-line electrical heater with two heating parts connected in parallel to allow the stripping solution to quickly return to the proper etching temperature, and returning the temperature recovered stripping solution to the process bath. The filtered stripping solution is branched through the parallel heating parts to enable it to be quickly heated. The stripping solution may be a phosphoric acid solution, whose proper etching temperature is about 163.degree. C. The in-line heater consists of at least two heating parts connected in parallel, each with an electrical capacity of 6 KW.
