Title: Thin film transistor
Inventor: KIMURA MUTSUMI
IPC: H01L21/336
Filed: 2000-02-01
Abstract: PROBLEM TO BE SOLVED: To suppress the secular change deterioration of a large-grain size polycrystalline thin film transistor. SOLUTION: The crystal grain boundary is limited to other regions than regions at the drain region side away from the midpoint between the source region and the drain region, or within 1 μm from the drain region or a region where the electric field density is over 1.0×105 V/cm. Owing to this constitution, no crystal grain boundary exists at a region where the electric field density is high and hot carriers appear. Thus a defect level is never formed at the crystal grain size boundary and the securer change deterioration can be suppressed. The region where the crystal grain boundary must not exist is not so wide, thus facilitating the manufacturing and allowing various crystallizing methods to be employed.

IPC: H04N1/40
Filed: 2000-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a picture processor which can prevent the forgery of an object whose copy is inhibited without troubling a copy operation. SOLUTION: A histogram showing the number of pixels with respect to density at every RGB signal of an original is generated based on the RGB signal from a reading part 14. Similarity at every RGB signal of the original is calculated based on the histogram and a histogram showing the number of pixel with respect to density at every RGB signal on the object whose copy is inhibited, which is stored in a ROM 12. When the similarity of the original is remarkably high, a copy operation is inhibited. When the similarity of the original is high, colors are reduced and the regular copy operation is conducted. When the similarity of the original is low, the regular copy operation is conducted. Even if the original similar to the object whose copy is inhibited is copied, the colors are reduced and the copy operation is conducted.  Thus, the forgery of the object whose copy is inhibited can be prevented without troubling the copy operation.
