Title: Nitrogen level sensor installation structure for anisotropic etching vessel
Inventor: OI HIROYUKI
IPC: H01L21/306
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a nitrogen level sensor installation structure for anisotropic etching vessel, wherein the generation of the convection, which is harmful to an anisotropic etching, of an etching liquid is inhibited and anisotropic etching can be performed on the surfaces of wafers. SOLUTION: One part, which is located on the side of a nitrogen level sensor 13, of an etching liquid is sectioned from the residual etching liquid on the side of silicon wafers W, by a partition plate 14 in the interior of an anirsotropic etching vessel 11. Thereby, at the using of the sensor 13, N2 gas generated from the surface of this sensor rises only within the etching liquid, which is sectioned by the plate 14 and is located on the side of the sensor 13, reaches up to the liquid level of the etching liquid and is released to the atmosphere as it is. As a result, the generation of convection, which is harmful to anisotropic etching of the etching liquid is suppressed in the etching liquid on the side, which is housed with the wafers of the etching liquid. Accordingly, an anisotropic etching can be performed for the wafer surfaces.

Abstract: PURPOSE:To improve accuracy in measurement by providing a probe that is provided with a single magnetism detection element, a plurality of delay circuits that are for delaying signals from the detection element, a differential circuit that compares delay signals with instantaneous signals and calculates variation. CONSTITUTION:The probe 5 of a magnetic flaw detector is provided with one magnetic detection element 4, and the probe 5 scans with a relative speed V positions that are apart from a furface to be inspected by a certain distance. If, in this scanning, it is desired to detect with maximum sensitivity a leaking magnetic flux of which the distance between (a) and (b) is di, a delay signal that is delayed from an instantaneous signal by the distance of di or by the time of di/V is obtained from a delay circuit separately from the instantaneous signals, and this delay signal and the instantaneous signal are applied to a differential circuit. With this arrangement the delay circuit plays the role of the  element of a two-element type probe in conventional flaw detectors with the  result of detection of leaking magentic fluxes with maximum sensitivity and raised accuracy of inspection.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal device and its driving method which is simple while securing a sufficient bit plane time and prevented from deteriorating in display due to impurity ions. SOLUTION: In driving of liquid crystal devices for which either of the two states of ON/OFF is substantially selected, a difference Vshift between a threshold value V0 at the time of switching a state in which a driving waveform not generating internal DC (VR) is being applied to the liquid crystal devices, or in a state in which a 1st and a 2nd electrodes are shorted; and a threshold value Vth at the time of switching from the state in which a driving waveform generating the internal DC (VR) and also generating a liquid crystal alignment state equivalent to a liquid crystal alignment state by application of the above waveform or the above short-circuit is being applied;  the difference Vshift=V0-Vth is made to be in the range of |VR|<=|Vshift|<=4|VR|, and the internal driving waveform generating the internal DC is applied, and thus, an appropriate shift Vshift of threshold value is generated. Namely, since the internal DC acts to surely offset burning force even when the burning phenomenon occur, the threshold value is shifted in the easier switching direction, and it does not vary the threshold value within a fixed range in appearance, and the liquid crystal devices can be driven by the voltage before the internal DC is generated.
