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.
