Title: Semiconductor acceleration sensor, and method of manufacturing the same
Inventor: HAMADA YOSHIHIKO
IPC: H01L29/84
Filed: 2001-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor acceleration sensor of favorable productivity without generating a short circuit between electrodes in static capacity. SOLUTION: An opening part 18 is provided in part of a silicon substrate 1 composing a second layer to form such a constitution that a space forming a cavity 9 is connected to an external circuit through the opening part 18 only. The cavity 9 is a space between a fixed electrode plate 11 and the silicon substrate 1. In this constitution, a seal tape 17 is applied to close the opening part 18 in a process of separating and cutting the semiconductor acceleration sensor from a semiconductor wafer in manufacturing processes, and it is cut afterwards, so that invasion of cut chips or cutting water into the cavity 9 can be prevented. A process of inspecting if there is invasion of the chips or the cutting water or not, or a process of eliminating them can thus be dispensed with.  A high reliability semiconductor acceleration sensor of improved productivity without having the short circuit between the electrodes in static capacity in the cavity 9 can thus be provided.

Title: Rotary wafer processing apparatus and method therefor
Inventor: SHIBAO TAKUYA
IPC: B05D7/00
Filed: 2001-05-16
Abstract: PROBLEM TO BE SOLVED: To improve product quality and yield by properly performing processing in a treatment mode in a device for rotating type wafer processing having a plurality of kinds of treatment modes in which predetermined processing for a wafer is performed, while rotating the wafer, and to provide a method for the same. SOLUTION: When the velocity of a wafer-supporting board 11 is increased to a maximum velocity Vmax, in end portion 131 of a center support pin 13 is lowered to a lowest position Hmin. As a result, the height of the central surface of the wafer is considerably lower than that of the periphery in a bowl- like shape. The wafer is dried by shaking into such a bent state. Thus, by supporting a wafer W in a smoothly bent state, local corrugations (depressions and projections) of the wafer W can be prevented, and vibration of the wafer can be suppressed, even when the wafer is rotated at a high speed.

Title: Recorder, its control method and program
Inventor: FUJIMAKI OSAMU
IPC: B41M5/30
Filed: 2001-06-01
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable recorder which can surely erase written information without damaging a medium. SOLUTION: There is provided the recorder 1 which is equipped with two modes different in the time for irradiating light to the medium 2. When a reversible thermal recording paper is set as the medium 2, the medium can be rapidly cooled by irradiating light of the short irradiation time at a write time, and can be gradually cooled by irradiating light of the long irradiation time at an erase time. Both writing and erasing are enabled by irradiating light to the reversible thermal recording paper. Moreover, the need of holding to an achromatic temperature region is eliminated at the erase time where a temperature control is difficult. The recorder 1 can surely write and erase information by the simple configuration. In addition, since the erasure is carried out indirectly by light, the fear of damaging the medium is eliminated.
