Title: Formation of resist pattern
Inventor: KATO YOSHIHIDE
IPC: G03F7/20
Filed: 1984-08-15
Abstract: PURPOSE:To form a highly accurate ultra-miniature resist pattern while realizing simplification of manufacturing processes and curtailing manufacturing time by selectively dry-etching the region not irradiated with energy beam with the graft polymer film formed on a polymer film used as the mask. CONSTITUTION:A polymer film 3 of polymethylmethacrylate (PMMA) is formed on a silicon substrate 1 by the rotary coating method and is then subjected to a heat processing at 180 deg.C. It is then selectively irradiated with electron beam 4 and the polymer film selectively activated and vapor 5 of vyniltrichlorosilane are placed in contact at the energy irradiation region to form a graft polymer layer 6. The PMMA of non-irradiated region 8 is eliminated by executing the reactive ion etching 7 in the reactive gas ambient with this polymer layer 6 used as the mask and thereby a negative resist pattern can be obtained. Reduction of film of the graft polymer layer 6 in such reactive ion etching process is as small as 100Angstrom and can be disregarded. Since this etching process has anisotropy, there is little side etch and a resist pattern obtained is very accurate.

Abstract: PURPOSE:To positively break the thyristor to be used for damping when the subject motor is at a standstill by a method wherein the antiparallel circuits of a diode and a thyristor are connected in series to an armature, and the gate of the thyristor is controlled by a constant-voltage diode. CONSTITUTION:When a signal is given to the thyristor for damping from a trigger circuit 5 at the time when a damping is performed, an armature wiring circuit 3b is short-circuited, counter-electromotive force is generated, the constant- voltage diode 8b is turned to conductive by the voltage generated as above, the thyristor 7 is turned to ON position, a backward current is applied to the armature wiring circuit 3b, and the motor comes to a stop quickly. Then, after the motor has stopped, when the signal of the thyristor 4 for damping is broken, the thyristor 7 is turned to OFF position by the working of the constant-voltage diode 8b, and the thyristor 4 for damping is turned to OFF position. Accordingly, the thyristor 4 for damping can be turned to OFF without fail even when electromotive force is remained in the armature winding circuit 3b when the motor is at a standstill, and a non-controllability of damping and a rise in temperature can be prevented.
