Title: Formation of gate electrode
Inventor: OGAWA KICHIJI
IPC: H01L29/78
Filed: 1987-07-08
Abstract: PURPOSE:To improve the breakdown strength of the device as well as to improve its reliability by a method wherein an amorphous silicon layer and a polycrystalline silicon layer are laminated successively on the surface of a gate insulating film, and the gate electrode having a smooth surface is obtained by conducting selective etching on said two silicon layers. CONSTITUTION:A gate insulating film 3 is formed by selectively providing a field insulating film 2 on the surface of a one-conductive type silicon substrate 1. Then, an amorphous silicon layer 4, containing oxygen of 1-20 atomic % is formed on the gate insulating film 3 by conducting a thermal decomposition method at the pressure of 0.5Torr and at the temperature of 600 deg.C using the mixture of silane gas and nitrous oxide gas. Then, a polycrystalline silicon layer 5 of 0.5mum in thickness is deposited on the layer 4 by conducting a silane gas thermal decomposition method at the pressure of 0.5Torr and at the temperature of 640 deg.C without exposing the surface of the amorphous silicon layer 4. A gate electrode is formed on the above-mentioned element formation region by conducting selective etching sucessively on the polycrystalline silicon layers 5 and the amorphous silicon layer 4.

Title: Electrostatic developing device
Inventor: IKEGAWA AKIHITO
IPC: G03G21/00
Filed: 1990-06-29
Abstract: PURPOSE:To execute proper electrostatic charge and exposure by eliminating residual developer on an electrostatic latent image carrier to such an extent that there is no difficulty in practical use at a developing part and disturbing the residual developer with the aid of an electrostatic charging brush. CONSTITUTION:The electrostatic charging brush 4 is supported by a projecting arm part 20 integrally formed in the developing part 2 and is in contact with a photosensitive drum 1. The developing part 2 and the brush 4 form an electrostatic developing unit A and they can be attached and detached with respect to a printer main body. In such a way, the surface of the electrostatic latent image carrier can be electrostatically charged to desired potential by the brush part 4. Besides, an electrostatic latent image on the image carrier is developed and made a visible image by the developing part 2. Simultaneously, the developer at a non-image part left on the image carrier is eliminated after transfer. Besides, when the residual developer is passed through the electrostatic charging brush, the pattern thereof is disturbed while it collides with the bristle of the brush. Thus, the proper electrostatic charge and the proper exposure are realized without being disturbed by the residual developer.

Filed: 1986-07-22
Abstract: PURPOSE:To prevent characteristics in a semiconductor device from being deteriorated accompanying leakage of hydrogen, by covering the whole surface containing the semiconductor substrate with silicon nitride and titanium nitride. CONSTITUTION:A silicon nitride film 2 is formed on the surface of an insulating substrate 1, or the insulating substrate 1 is made of silicon nitride itself. A semiconductor film 3 is then formed thereon and used to compose a MOS type semiconductor device or the like.
