IPC: H04N5/85
Filed: 2003-02-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a DVD player capable of shortening time required up to notification that a still image file can not be reproduced to a user by analyzing the header of the still image file and judging whether the file can be decoded by a decoder or not before starting reproducing processing and capable of improving operability.  <P>SOLUTION: When an extender of a still image file whose reproduction is instructed is JPG, the DVD player 1 analyses the header of the file and judges whether the file is a still image file of a reproducible format or not. At the time of judging that the file is a still image file of a reproduction disabled format, a video signal indicating the judged result is outputted. Since a user can be quickly informed of the result that the still image file whose reproduction is instructed is a file which can not be reproduced, user's operability can be improved.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for evaluating resist separation performance for obtaining a reliable result inexpensively and simply, and also to provide a method for manufacturing a semiconductor device and the semiconductor device utilizing the method for evaluation.  <P>SOLUTION: A base film is formed on a semiconductor substrate (S1), and a resist film is formed on a base film (S2). The resist film is separated (S3). Next, the base film is removed by the portion of an optional thickness from an exposed surface (S4). In this case, etching is performed in a manner where a part where the resist film remains on the base film (residual part) is not etched. Next, the presence/absence of the residue of the resist film is detected (S5). In an area from which the resist film is completely removed, the base film is equally lowered by the portion of the optional thickness. Since the base film is not etched in the residual part of the resist film, a level difference is emphasized with the residue there. Thus, it becomes easy to detect the presence/absence of the residue of the resist film.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
