Abstract: A double patterning method of manufacturing select gates and word lines is provided in the present invention, including forming first string patterns composed of word line patterns and select gate patterns on a target layer, forming a conformal spacer layer on first string patterns, wherein the spacer layer forms trenches between first string patterns, forming a fill layer filling up the trenches on the spacer layer, removing fill layer outside of the trenches, so that fill layer in the trenches forms second string patterns, wherein the second string patterns and the first string patterns are spaced apart, removing exposed spacer layer, so that the first string patterns and the second string patterns constitute target patterns spaced apart from each other on the target layer, and performing an etching process using those target patterns as a mask to remove exposed target layer, so as to form word lines and select gates.

Abstract: A method of cleaning a wafer in semiconductor fabrication is provided. The method includes cleaning a wafer using a wafer scrubber. The method further includes moving the wafer scrubber into an agitated cleaning fluid. The method also includes creating a contact between the wafer scrubber and a cleaning stage in the agitated cleaning fluid. In addition, the method includes cleaning the wafer or a second wafer by the wafer scrubber after the wafer scrubber is cleaned by the agitated cleaning fluid.

Abstract: A method for seamless playback of multiple multimedia files is provided. First, a first multimedia file and a second multimedia file are pre-analyzed to establish a playing list. Next, index content of the first multimedia file and the second multimedia file are referred to, so as to establish a first random access table and a second random access table. Then, the multiple multimedia files are played according to the play list, the first random access table, and the second random access table. Accordingly, the multiple multimedia files can be played seamlessly while the video and audio data are kept synchronized, such that the continuity for viewing multimedia files is improved.

Abstract: An error recovery method for recording an audio-video interleaved (AVI) file is provided. The AVI file includes a header chunk and a content chunk. First, the predetermined values of a plurality of recording information are respectively written into a plurality of corresponding fields in the header chunk and the content chunk, wherein the recording information is related to a video/audio length of the AVI file. Next, a multiplexed media data is written into the content chunk for recording the AVI file. After the AVI file recording is finished, the corresponding fields in the header chunk and the content chunk are corrected according to the actual values of the recording information. Thereby, even if the recording process is abnormally terminated, the AVI file can still be normally accessed for it has a complete and legitimate structure.
