Title: Method for washing photomask, apparatus therefor and photomask washing solution
Inventor: NAGAMURA YOSHIKAZU
IPC: G03F1/82
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To allow a small amount of a chemical solution to produce a removing effect comparable to or higher than the conventional effect and to reduce the amounts of chemicals and pure water used by removing foreign matter sticking to the surface of a photomask with water containing dissolved gaseous H2. SOLUTION: In a step 1, a photomask is washed with a hot mixed solution of sulfuric acid and hydrogen peroxide so as to degrade organic materials such as a resist and a solvent present on the surface of the photomask, to improve the wettability of the surface and to remove metallic impurities. In a step 2, the photomask is washed so as to remove the residual sulfuric acid and foreign matter sticking to the surface of the photomask. When a light shielding film formed on the photomask is a CrON film, fine particulate foreign matters sticking to the surface of the photomask are removed by megasonic ultrasonic treatment with water containing dissolved gaseous H2 or further containing a very small amount of ammonia. In a step 3, the washed photomask is dried.

Title: Printer
Inventor: FUJIWARA TAKASHI
IPC: B41J2/00
Filed: 1984-07-06
Abstract: PURPOSE:To enable printing speed to be enhanced without lowering printing quality, by providing a means for discriminating whether a system to be used is a high position accuracy printing system or a normal position accuracy printing system, and a means for switching the velocity of a carriage on the basis of the result of discrimination. CONSTITUTION:A typing mode or a printing mode is selectively set by a switch 20d. With the mode thus set, a CPU9 discriminates a system conforming to the mode, and sends a signal for controlling the velocity of the carriage 14 to a motor-driving circuit 16. Where one of keys 20a, 20b, 20c is depressed under the condition in which the mode is set as above, the CPU9 reads a signal of a bit 21a, judges the length of latency time, and after the lapse of the latency time, the CPU9 sends a printing signal to a printing hammer driving circuit 11. Accordingly, since the latency time from the time of stoppage of the carriage 14 to the moment a printing hammer 10 strikes a type 6 is set by the CPU6 to be long in the high position accuracy printing system and to be short in the normal position accuracy printing system irrespectively of the distance of movement of the carriage 14, the printing speed can be enhanced without lowering the printing quality.
