Title: Integrated circuit device and method for forming resistance elements used in integrated circuit
Inventor: JOSE BECK
IPC: H01L31/058
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To manufacture resistance elements so as to enable reproduction, by forming the resistance elements, using nonlinear silicon having specified resistivity. SOLUTION: After a stepped layer 110 is formed on a silicon substrate 100, a patterned first conducting layer 116 is formed on a stepped surface layer of the stepped layer 110. An insulating layer 120 as a second layer is formed on the first stepped layer 110, which has been subjected to step treatment. In this case, the patterned first conducting layer 116 is formed on the stepped layer 110. A via 125 is formed in the insulating layer 120 and is filled with silicon 130 (amorphous or polycrystalline). Thus, each of resistance elements 135, 140, 145 is formed with a different length and identical width. Since the resistivity of the silicon 130 is constant which is at least about 105Ω per cm, the resistance values of the resistance elements 135, 140, 145 become a function of the lengths of the resistance element.  Thereby control which is capable of easy reproduction is made possible.

Title: Fur brush cleaner
Inventor: SOUMIYA TOKUMASA
IPC: G03G21/00
Filed: 1981-10-16
Abstract: PURPOSE:To permit controlling of the rotating speed of a fur brush according to rotating pressure and maintaining the cleaning performance of the fur brush at high performance at all times by providing a detecting means which detects the rotating pressure of the fur brush in the position where said means can contact with the fur brush. CONSTITUTION:A fur brush rotates at an initial rotating speed in the normal stage. On progression of use, the pressing force of the brush hair 8a onto the surface of a photoreceptor decreases as the abrasion of the brush hair 8a and the deterioration owing to its deformation such as lying habits arise. This decrease leads simultaneously to a decrease in the rotating pressure detected by a pressure sensitive element 9 which feeds a detection signal immediately to a control unit 10. The unit increases the driving force of a motor 11 to increase the rotating speed until the normal rotating pressure is restored, whereby always the normal cleaning performance is obtained.

Title: Semiconductor device and manufacture thereof
Inventor: MISHIMA TATSUO
IPC: H01L21/76
Filed: 1990-06-22
Abstract: PURPOSE:To easily provide transistors with effective input resistance in the manufacturing process by forming a polysilicon film on the edges outside isolation trenches, and connecting the polysilicon between contact electrodes so that it serves as input resistance to the base or collector. CONSTITUTION:A semiconductor process includes removing an Si3N4 film 6 used as a mask in the final step of forming isolation trenches 7. If the device is treated with hydrofluoric acid after the removal of the Si3N4 film 6, then an SiO2 11, covering the trench, and a field oxide 5 (SiO2) are etched, resulting in a larger step at the edge of the trench 7. On the other hand, polysilicon 13 for base and collector contacts remains at the step. Therefore, the polysilicon 13C remaining in the trench 7 for isolation of individual transistors is electrically connected with polysilicons 13A and 13B for base and collector contacts. The polysilicon 13C at the edge of the trench is positively utilized as an internal input resistor to the base or collector or a transistor.

Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a capacitor array which can reduce the generation of crosstalks. SOLUTION: In a capacitor array 20, an internal electrode 22 constituting three capacitors 20a to 20c is formed inside a nearly rectangular parallelepiped- shaped element assembly 25, and three pairs of external electrodes 26 which are connected conductively to the internal electrode 22 are formed on two opposite side faces of the element assembly 25. In this case, a region in a prescribed depth from the side faces (external-electrode formation faces) of the element assembly 25 at least in a part positioned between the adjacent external electrodes 26 is used as the element assembly 25, formed on an insulator 24 the permittivity of which is lower than that of a dielectric substance which forms other regions.  Thereby, since a stray capacitance generated across the external electrodes 26 is reduced, it is possible to reduce crosstalks between different signal generated by the stray capacitance.

Filed: 1987-06-30
Abstract: PURPOSE:To satisfy product catalog requirements even by performing access time check at the time shipping test in the erased state by selecting the readout access time of memory information in the erased state as the maximum access time. CONSTITUTION:An address switching detection circuit 2 sets a sense amplifier circuit 5 and an output buffer circuit 6 so as to have a memory information output in the latest write state of the access time in the voltage level. Thus, even in the address access time when the selected memory information is switched from '1' to '1' is read once through the level '0' and the address access time is used as the maximum access time. Since the readout address access time in the erased state, that is, when all bits are logical 1 is set to the maximum access time without fail, the access time test satisfying the requirement of the product catalog is executed by only the access time check in the erased state.
