IPC: H01L21/8242
Filed: 2000-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device and its manufacturing method that form memory and logic devices on the same semiconductor substrate, without complicating the manufacturing processes. SOLUTION: A silicide protection film formation process of a logic device region is eliminated, and the sidewall of a gate electrode is also used as a silicide protection film, thus reducing the number of processes in formation of a mixedly mounted device. Also, the silicide protection film is used as a mask for forming a heavily-doped impurity region, thus increasing the degree of freedom for ion implantation conditions. In the memory device region, since the silicide protection film does not exist, forming an opening part in self-aligned manner without reducing the reliability of the semiconductor device, and hence electrically connecting the source and drain regions of the semiconductor device to a wiring layer satisfactorily at the self align contact opening of the memory device region.

Title: Image processor and method for image processing and recording medium with program of image processing recorded thereon
Inventor: ICHIKAWA YOSHIKUNI
IPC: G06T3/00
Filed: 2000-01-18
Abstract: PROBLEM TO BE SOLVED: To provide a picture processor which easily and quickly composites picture data different in resolutions and quickly performs image processing without degrading the image quality. SOLUTION: The image processor is provided with an original image input part 1, a block division part 2, a block storage part 3, a block change processing part 4, an output selection part 5, and a image conversion pat 6. In the stage of image change processing, change processing is performed in the unit of blocks with respect to each image, and an enlargement/reduction rate and a transparent state of each image are set and images are converted to data suitable for an output device when the output device is finally selected. Thus, the time required for image change processing is shortened, and the memory capacity for work is reduced. Since images can be managed in the unit of blocks, only required blocks can be stored in a main memory, and the main memory is efficiently used.  Since it is sufficient if bit map data of only blocks of parts where images exist are stored, the data volume of image is reduced.
