Title: Alignment equipment
Inventor: MIYAZAWA TOSHIO
IPC: H01L21/68
Filed: 1992-01-29
Abstract: PURPOSE:To accurately detect a notch and perform alignment, independently of whether material constituting an object to be processed is transparent. CONSTITUTION:The peripheral part of an object 18 to be processed mounted on a prealignment stage 30 of a rotary means 50 is irradiated with ultrasonic wave M from an ultrasonic transmitting part 54 arranged above the object, and the reflected wave is received with an ultrasonic wave receiver 56. Since the amount of the reflected ultrasonic wave is proportional to the area of a reflecting surface, the output decreases when a notch passes a measuring part. Hence a control part 58 can recognize the position of the notch, and drives the rotary means 50 according to the recognition result and the output result of a rotation angle detecting means 52. Thereby the notch of the object 18 to be processed is set at a specified position.

Title: Measurement of fluid flow velocity
Inventor: YOSHIDA MASAFUMI
IPC: G01P5/00
Filed: 1979-03-31
Abstract: PURPOSE:To accomplish higher reliability of fluid flow velocity measurement using the value independent of the objective measurement value as the reference value in the measurement of the fluid flow velocity employing acoustic wave including supersonic wave. CONSTITUTION:Acoustic wave is received or transmitted in the opposite direction to each other between transmitting devices 1 and 2 and receiving devices 3 and 4 are separated at a fixed space L as opposed to each other to detect the propagation times t1 and t2 of each acoustic wave in the opposite direction. The value, T=(t1+ t2)/t1t2, is computed to be memorized in the comparison value memory circuit 10 as comparison standard value T0. At the same time, from the propagation times t1 and t2, the value corresponding to the fluid flow velocity, wind speed, vector Vx is determined by computing the equation of [(t2-t1)/t1t2]L/2 and memorized so temporarily in the register 7 to allow continuous output. The value T is used as the noise decision value. When the noise decision value obtained at a certain cycle with respect to the T0 exceeds the allowable range succesively at N cycles, the comparison standard value is corrected adopting the noise decision value T at the cycle N as the new comparison standard value T0. Thus, highly reliable fluid flow velocity measurement can be done.

Title: Step-difference measuring apparatus, etching monitor using the same, and etching method
Inventor: KUSUSE HARUHIKO
IPC: G03F1/84
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To enable to measure a step-difference of fine depth formed on a transparent substrate, from the rear of the transparent substrate. SOLUTION: Two light beams having coherency are cost from the rear of a transparent substrate, and reflected by the respective step-difference surfaces. The two reflected beams are synthesized to be an interference beam. In this case, the optical distance of one optical path is changed continuously in time. This interference beam is received with a photo detector 34 and converted to an electric signal. An output signal of the photo detector 34 contains phase information caused by the step-difference and phase information which is compulsorily introduced. A signal processing circuit 35 stores the relation between time and photo detector output intensity. By comparing phase information before the step-difference is formed with phase information after the step- difference is formed, the phase information caused by the step-difference can be led out as the amount of phase shift.

Title: Semiconductor device and operation thereof
Inventor: FUJIWARA HIDEAKI
IPC: H01L29/792
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor memory which can realize a long life, low voltage, high-speed operation, low power consumption and high integration. SOLUTION: With respect to operational voltages of a memory cell 21a, a source voltage VS is set at 3V, a drain voltage VD is at -3V, and a control gate voltage VCG is at 3V. This causes an electric field to be applied to a polysilicon spacer 15a so that electrons passed through a Schottky barrier between a drain electrode 16 of tungsten silicide and the spacer 15a are accelerated in the electric field. An energy necessary for the electrons to exceed a barrier of an insulating film 14a as a silicon oxide film is 3.2 eV, and a mean free path at this time is about 30-40 nm. Thus, when the spacer 15a is set to have a thickness of 30 nm, nearly all the electrons acquire the energy exceeding the barrier of the insulating film 14a to form hot electrons, whereby the hot electrons are injected into a floating gate electrode 8a at a very high probability without staying in the spacer 15a.
