Title: Color thermal printing method
Inventor: SATO MASAMICHI
IPC: B41J35/16
Filed: 1994-12-21
Abstract: PURPOSE: To prevent the density irregularity due to a load change owing to the pressure contact and the retraction of a thermal head with a recording sheet. CONSTITUTION: After a color thermal recording sheet is conveyed and passed under thermal heads, the heads are simultaneously moved to thermal recording positions in pressure contact with the sheet. A full-color image is recorded on the sheet by the heads. After all thermal recordings are finished, the heads are simultaneously moved to retracted positions separate from the sheet. Accordingly, after all the heads are brought into pressure contact with the sheet, thermal recording is conducted, and after the thermal recording is finished, all the heads are retracted from the sheet, and hence no abrupt load change occurs in the case of conveying the sheet, and no density irregularity occurs.

Title: Method of manufacturing semiconductor device
Inventor: KISHIMOTO KOJI
IPC: H01L21/28
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device by the elimination of a copper oxide (CuxO) 108a or the like formed on the surface of copper in a damascene copper interconnection 107a or the like by a plasma CH4 treatment 109 and the capping of the surface with a plasma silicon nitride film 110 without exposing the surface to the air. SOLUTION: The existence of a copper oxide causes an easy separation of a silicon nitride film, especially a plasma silicon nitride film of a larger area on a copper interconnection. A poor adhesion causes copper atoms to move easily in an interface, and cause the deterioration in electromigration. In order to avoid this problem, the surface is treated with a plasma CH4. Carbon atoms absorbed by the surface selectively remove oxygen from the copper oxide and then become volatile CO molecules to be easily removed from the surface of the copper interconnection. Carbon also works as a reducing agent for hydrogen and therefore a reducing action by hydrogen can be increased.

Filed: 1989-12-11
Abstract: PURPOSE:To improve soft error resistance by inserting two laminated type transistors set independently at substrate potentials between cross-connection drain and gate of a flip-flop contained in a memory cell. CONSTITUTION:A word line W is set to an L level in a storing state, laminated transistors Tr Q74, Q84 are interrupted. However, since the threshold voltages of the Trs Q74, Q84 are set to low values, a small drain current flows to the Tr Q74 (Q84), and the value becomes sufficiently larger than gate leakage currents of transistors Q3, Q5 (Q4, Q6). Accordingly, the Trs Q74, Q84 are operated with high resistance in this state to suppress variation of potential at a common node d(c) due to incident alpha-rays, etc., to the drain of the transistor of the OFF state, thereby enhancing its soft error resistance.
