Title: Word-line load compensation circuit of semiconductor memory device
Inventor: RI EITAKU
IPC: G11C11/407
Filed: 1994-11-16
Abstract: PURPOSE: To improve reliability by preventing the insulation destruction of a capacitor by an excessive stress voltage for a word line load compensation circuit for compensating the change portion of a word line load to a word line voltage. CONSTITUTION: When load compensation is required, enable signals ϕEN become logic '1'. Then, word line voltage generation by a word line boosting circuit 5 is started and delay signals DE by a delay circuit 60 are outputted by the logic '0' until a saturation level is attained. Thus, the output of a NOR gate 65 becomes the logic '1', a transistor 80 is turned ON and excessive electric charges are stored in the capacitor 85. Matched with the word line voltage becoming the saturation level, the delay signals DE are shifted to the logic '1' and thus, the output of the NOR gate 65 becomes the logic '0' and the transistor 80 is turned OFF. Simultaneously, the transistor 90 is turned ON and the electrode of the capacitor 85 is grounded. Thus, thereafter, the stress voltage is not applied to the capacitor 85.

Abstract: PROBLEM TO BE SOLVED: To make the travel of a car body and the movement of a face synchronize with each other securely in a highly accurate manner by calculating a thrust in the load placing work direction of a push-pull cylinder based on the detection pressure and, after contact between the face and a load is detected from this calculation, controlling the movement of the face so as to synchronize with a traveled variable of the car body. SOLUTION: A controller 16, equipped with pressure detecting means 41 detecting the extent of pressure in a push-pull cylinder in a hydraulic circuit, calculates a thrust in the load placing work direction of this push-pull cylinder on the basis of a pressure signal out of the pressure detecting means 41 in time of load placing, detecting contact between a face and a load from this calculation, and it controls it so as to stop the travel of a car body unless the contact between the face and the load is detected. In succession, the controller 16 stops the travel of the car body up to the time of detecting the contact between the face and the load in time of load placing by a thrust rise.  When the contact between the face and the load in time of load placing by this thrust rise is detected, this controller is made so as to do its synchronous control synchronizing those of face movement and body travel together.

IPC: H01L21/304
Filed: 1989-10-30
Abstract: PURPOSE:To prevent the contamination of the inside of a trench by concentratedly heating the cleaning solution adhering to the surface of a semiconductor water and remaining in the trench by irradiating the surface of the wafer with microwaves. CONSTITUTION:During the course of the process from cleaning to drying, the surface of a semiconductor wafer 3 is irradiated with microwaves. Namely, the microwave energy is supplied through waveguides 14, an opening between the waveguides 14, and the wall of a drying device 6A from a magnetron 16 and the microwave energy entering into the drying device 6A collides with the moisture on the surface of the wager 3 and, especially, in a trench and is converted into microwave energy in pure water. Since the wafer 3 rotates together with a turntable 12, the surface of the wafer 3 is uniformly irradiated with the microwave energy and the moisture on the surface of the wafer and in the trench is selectively and quickly heated concentratedly and evaporates to disappear. Therefore, formation of colloidal silica which is produced by the reaction between the pure water and silicon can be eliminated and contamination of the wafer can be prevented.
