Title: Semiconductor device and manufacturing method for the semiconductor device
Inventor: ARAI NORIHISA
IPC: H01L27/10
Filed: 2001-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent remaining of unetched parts and overetching, even when simultaneously patterning a high concentration region and a low concentration region. SOLUTION: After forming an element isolation oxide film 118, a CMP is conducted with a silicon nitride film 118 as a stopper and the element isolation oxide film 118 is planarized. Thereafter, when the silicon nitride film 118 is removed, a step A' is formed between the peak part of the element isolation oxide film 118 and polysilicon films 106 and 113. Then, when the polysilicon film is deposited further on the polysilicon films 106 and 113, 'drift' of the polysilicon film is generated, and the film becomes thick on the side of a memory cell region and the drift is not generated on a peripheral circuit region.  In order to offset the difference in the total thickness of the gate electrode film due to that, the film thickness of the polysilicon film 113 in the peripheral circuit region is formed larger than the film thickness of the polysilicon film 106 in the memory cell region by a prescribed amount.

Filed: 2001-07-26
Abstract: PROBLEM TO BE SOLVED: To provide an ice making device capable of making it easy to gather water containing mineral and gas components in ice making blocks on one side, and to provide a refrigerator-freezer. SOLUTION: In the ice making device, a blowing mechanism which supplies warm air at a prescribed blowing angle to the ice making blocks is provided and a communicating part through which the water in the adjacent ice making blocks can go and come between them is formed in an ice making tray, while lateral walls in the upper parts of the blocks are formed in such a shape, e.g. a substantial octagon that makes it easy for the water flowing in the communicating part to move along them. Accordingly, the water near the lateral walls goes and comes easily through the communicating part along the flow thereof caused by the warm air sent from the blowing mechanism, and thus the water containing the mineral and gas components and being resistant to freeze is easily collected to the side of the ice making blocks located in the direction of blowing the warm air.  Therefore, the ice on the side opposite to the ice making blocks in the direction of blowing the warm air can be made transparent substantially.

Title: Image processing unit, image processing method, print controller, and recording medium
Inventor: SUMIYA SHIGEAKI
IPC: G06F3/12
Filed: 2001-08-06
Abstract: PROBLEM TO BE SOLVED: To provide an image processing unit, an image processing method, a print controller, and a recording medium that can quickly convert image data into print data expressed in the presence/absence of dot formation without deteriorating the image quality. SOLUTION: An intermediate buffer stores temporarilly a gradation error caused in a pixel to be discriminated according to presence/absence of dot formation. After determining a prescribed number of pixels, a spread error that is spread to surrounding pixels not discriminated is calculated from a gradation error stored in the intermediate buffer and spread to an error buffer. Thus, in comparison with the case that the error is spread to the error buffer every time a gradation error takes place, the gradation errors can quickly be spread by the share of spreading the gradation errors by a prescribed number of pixels. A processing mathematically similar to the mean error minimizing method can be realized by utilizing the method above.
