Title: Ashing device
Inventor: OZAWA HIDEKI
IPC: H01L21/3065
Filed: 1994-06-09
Abstract: PURPOSE:To make uniform the temperature distribution in a chamber by a method wherein a flow passage, in which a cooling medium is allowed to flow, is provided in the chamber which is heated up by the rise in temperature by heating. CONSTITUTION:The water, which is conveyed to a water-leading pipe 30 from a temperature-regulated water introducing inlet 30S and discharged from a temperature-regulated water outlet 30D, functions as a cooling medium, the water is cooled down to the prescribed low temperature before it is fed from the temperature-controlled water introducing inlet 305. Also, a cooled water flow passage 40, which is spirally formed, is arranged on the outer wall of a chamber 1 formed from the top plate 3 to the bottom plate 2. The above- mentioned cooling water flow passage 40 is formed in such a manner that the water is fed from a cooling water introducing hole 40 and it is exhausted from a cooling water outlet 40D. According to this constitution, as the water leading pipe 30 is provided on the upper plate part 3 which becomes high temperature by heating, this part is prevented from becoming the temperature higher than the other part, and the temperature in the chamber can be made uniform.

Filed: 1983-07-15
Abstract: PURPOSE:To obtain a method effective in application to the semiconductor device having two or more kinds of electrodes made of different materials by utilizing the phenomenon that SiO2 is formed relatively thickly on Si or poly Si doped with As at high concentration by low temperature wet oxidation. CONSTITUTION:In the case of a Schottky barier diode, an oxide film is formed on the surface of the poly Si layer 9 doped with As at a high concentration more thickly than on the surface of the other active region by low temperature wet oxidation. Then, the oxide film 12 is left thin by etching, and platinum series electrodes 14 are formed at the parts of a base electrode 13B, a collector electrode 13C, and a barrier electrode 13b. At this time, since the film 12 remains at the contact hole part of an emitter region 8, the layer 9 is not damaged by etching. The oxide film 12 on the region 8 is removed, and an aluminum series metal is evaporated and photoetched; thereby aluminum series electrodes 15 are formed on all of the electrode parts.

Title: Duplex data preserving device
Inventor: SUGIYAMA HITOSHI
IPC: G06F12/16
Filed: 1990-05-18
Abstract: PURPOSE:To surely switch a duplex operating state to a single operating state at a high speed when one of two shared memories has a fault by providing an input/output path cutting mechanism which cuts physically the input/output paths which connect the shared memories and the clusters. CONSTITUTION:For instance, a cluster 12-1 separates a shared memory 10-1 due to the detection of a fault occurred in an area 1 of the memory 10-1. Under such conditions, an input/output path cut processing part 13 cuts physically the input/output paths P11 - P31 which connect the memory 10-1 and all clusters by means of an input/output patch cutting mechanism 11-1. When the clusters 12-2 and 12-3 have accesses to an area 1 of the memory 10-1, a program check state occurs owing to the physical separation. Thus the separation of the area 1 can be recognized with no performance of the inter-cluster communication. Thus it is possible to surely switch a duplex operating state to a single operating state at a high speed when one of the shared memories has a fault.

Abstract: PURPOSE:To detect the differential value of a load which acts upon a piezoelectric element by detecting the level of current flowing through an impedance forming a closed loop with the piezoelectric element for generating an electric charge which is proportional to the electric charge using a current detection circuit. CONSTITUTION:A sensor consists of a closed circuit which consists of a piezoelectric element 1 for generating electric charge when a load is applied and an impedance 2 and a current detection circuit 3 for detecting current flowing into the impedance 2.

The amount of change in the electric charge at this time is proportional to the change in the load and the level of current flowing through an electrical circuit constituting a closed loop with the piezoelectric element 1 which is a differential value regarding the time of electric charge is proportional to the differential value of the load. Therefore, by detecting the level of current flowing through the electrical circuit using the circuit 3, the differential value of the load acting upon the element 1 can be detected.
