Title: Preservation of semiconductor substrate and manufacture of semiconductor device
Inventor: SAGA KOICHIRO
IPC: H01L21/306
Filed: 1995-03-27
Abstract: PURPOSE: To provide a very clean semiconductor substrate which has no organic contamination before it is processed by forming a natural oxide film of enough thickness on the surface of the substrate before putting it in a container. CONSTITUTION: An Si substrate 11 which absorbs metal impurities on its surface is washed with strong acid or strong oxidant as a washing process before preservation. Further, it is washed with an alkali solution. After that, it is washed with ozone-containing superpure water as a finishing washing and dried and then a clean natural oxide film 13 of enough thickness is formed on the surface of the substrate 11. When the cleaned substrate 11 is stored in a polypropylene container, organic matter adsorps the surface of the natural oxide film 13 in a short time owing to outgas of the container. The Si substrate is delivered to a user in the container. At the user site, the substrate is preliminarily washed by being dipped in a hydrofluoric acid aqueous solution to remove the organic contamination 14 together with the natural oxide film 13 just before film formation or etching.  Immediately after the preliminary washing, a film is formed or etching is conducted on the substrate.

Title: Electrophotographic copying machine
Inventor: NAKAYAMA TOUICHI
IPC: G03G21/10
Filed: 1982-04-22
Abstract: PURPOSE:To prevent the disturbance of a toner image due to a removed carrier, by arranging a magnetic attracting means between a development part and a transfer part to remove the magnetic carrier which is stuck to the surface of the latent image of a photoreceptor together with a toner and transferring the toner well in the transfer process. CONSTITUTION:A magnet 10 as the magnetic attracting means is arranged between a developing device 4 and a corona discharger 5 for transfer so as to face oppositely to a photoreceptor 1. This magnet 10 is provided so as to face oppositely to the overall width of the photoreceptor in the axial direction of the photoreceptor 1. When a toner image part stuck to the latent image of the photoreceptor 1 faces the magnet 10, the carrier is attracted together with the toner to the magnet 10, and they are removed from the toner image part. That is, though the toner as well as the carrier may be stuck to the electrostatic latent image part simultaneously in the developing part, the stuck carrier receives the magnetic attraction and is attracted to the magnet 10 when it faces the magnet 10. At this time, the toner does not receive the action of the magnetic attraction and is not attracted to the magnet 10 because it is not a magnetic material. Thus, the image is transferred well without omission of image.

IPC: H01L29/10
Filed: 1979-06-02
Abstract: PURPOSE:To reduce source resistance or drain resistance by the method wherein a groove of the depth reaching a substrate from the surface of a source or a drain part is provided and connection to the substrate is done by the electrode formed in the groove. CONSTITUTION:P epitaxial layer 2 on p<+> substrate 1 has surface orientation (100) and forms n<+>-type source and drain layers 3 and 8. SiO2 film 9 is selectively opened, and by operating anisotropic etching from the surface of n<+> layer 3, groove 10 reaching substrate 1 is formed. Next, when source electrode 5', gate electrode 6 and drain electrode 7 are formed, electrode 5' attaches to the groove wall, and source layer 3 and substrate 1 are connected by electrode 5'. As a result, it is no longer necessary to form a p<+> diffused layer in the center of layer 3 as in the conventional method, so that no crystal defect or self-addition of an impurity occurs.  Further, it is possible to reduce source resistance or drain resistance by these electrodes.

Title: Level converting circuit
Inventor: YASUDA YOSHIYUKI
IPC: H03K19/0175
Filed: 1990-03-19
Abstract: PURPOSE:To obtain this level conversion circuit with less power consumption and a small occupancy area by constituting the level conversion circuit converting a signal whose high logic level is lower than 0V into a signal whose logic low level is higher than 0V with an output amplifying circuit and a current switching circuit. CONSTITUTION:The output amplifying circuit consists of CMOS inverters IV1, IV2. Thus, when the output amplifying circuit outputs a low level, since p- channel MOSFETs M1-M4 constituting the output amplifying circuit are turned off, a current flowing from a high level voltage source VDD to a current switching circuit is very small. Moreover, a steady-state current IO flowing through the constant current circuit to a 2nd low level voltage source VEE is not supplied from the high level voltage source VDD but supplied from a 1st low level voltage source VSS via n-channel MOSFETs Q4, Q5, the power consumption of the current switching circuit is considerably reduced. Thus, high speed output pull-up is attained, the power consumption is reduced and the occupancy area is decreased.
