Patent JP-H02239631-A (JP)
Title: Manufacture of semiconductor device
Inventor: NAKAMURA SHUNJI
IPC: H01L21/8222
Filed: 1989-03-14
Abstract: PURPOSE:To reduce a parasitic capacity between a base and an emitter and a parasitic capacity between a base and a collector by depositing a metal electrode to an aperture and by forming a Schottky barrier/diode region with the metal electrode and a nonion implantation region on a semiconductor substrate. CONSTITUTION:An ion injection region 5 is formed by introducing impurity of the opposite conductivity type to a part of an exposed section of a semiconductor substrate 1. An area which is behind a conductive layer 2 and an insulating film 3 and whereto impurity is not introduced becomes a nonionic injection region 6. After an emitter diffusion region 7 and an inner base diffusion region 8 are formed by double-diffusion P-type and N-type impurity inside the conductive layer 2, impurity in the ion injection region 5 is diffused to form an outer base diffusion region 9 which is in contact with the inner base diffusion region 8. Metal is deposited on an aperture 4 to form a metal electrode 10. The electrode 10 and the nonionic injection region 6 on the substrate 1 form a Schottky barrier/diode region 11. Thereby, a fine base, an emitter and a Schottky barrier/ diode can be formed, and a base to emitter parasitic capacity and a base to collector parasitic capacity can be reduced.

IPC: G03G15/00
Filed: 1990-03-13
Abstract: PURPOSE:To inform whether or not a copying action can be started in a set mode by giving warning in the case of judging that the copying action is impossible while a reservation copying mode is set. CONSTITUTION:This device is provided with a reservation key 602, a reservation setting key 603 and a liquid crystal type message display 711, and whether copying is possible or impossible is judged when a mode is set in a state where a reserved set mode is not cancelled. For example, in the case that the sorter of 20 bins is connected, a message, 'Please, set <=20 sheets.' is displayed on the message display in a sort mode which is set by mode setting and in the case of setting 30 sheets. In the case of specifying a page consecutive copying mode, a message, 'Please, don't use a feeder in page consecutive copying' is displayed. Thus, whether or not the copying action can be started is instantly informed by the set mode when a reservation copying mode is set or when it is finished to be set.
