Title: Plasma etching monitoring device
Inventor: FUJITA YOSHIRO
IPC: H01L21/3065
Filed: 1992-10-14
Abstract: PURPOSE:To monitor the time change of plasma density with high precision and to accurately detect the end point. CONSTITUTION:The optical axes of the laser beams emitted from the lasers 1 and 2 having a different wavelength are synthesized to constitute a laser interferometer 7. At this time, the short-wavelength visible laser beam 1 is used between the two laser beams, and the long-wavelength invisible laser beam 2 is used when plasma etching is monitored. When plasma etching is monitored, the long-wavelength invisible laser beams are passed through the separate laser beam paths and superimposed to cause interference. When the plasma enters one of the paths, the effective transmission length of the laser beam is changed by the refractive index of the plasma, and the phase of the interference laser beam as the transmitted light is shifted. The refractive index of the plasma and the plasma density as well are calculated by measuring the phase shift.

IPC: G03B17/08
Filed: 1993-11-04
Abstract: PURPOSE:To reduce load for advancing/retreating a lens barrel and to make stress exerted on a camera small by constituting a lens barrel part so that it may be extended by a position control means when a non-airtight state is caused by switching a changeover member. CONSTITUTION:When a back cover is opened in order to load film, a back cover switch SB is turned on and a CPU 20 controls a lens barrel control circuit 21, so that the lens barrel is extended to a position to obtain middle internal pressure between the internal pressure at the time of maximum extending and the internal pressure at the time of maximum retreating. Thereafter, by closing the back cover and operating a zoom-up switch SU or a zoom-down switch SD, the CPU 20 controls the control circuit 21 so as to perform the extending or the retreating of the lens barrel. It is not always the back cover that disturbs the airtightness of an equipment main body. In the case the non-airtight state is caused by other members, the lens barrel is extended to a position (m). Pressure sensors 22 are provided on the inside and the outside of a camera main body and measure the external pressure and the internal pressure.

Abstract: PURPOSE:To acquire a method to discriminate and detect an abnormal layer of a wafer non-destructively, accurately and easily, by bringing a probe into contact with the surface of an epitaxial layer of an epitaxial wafer of light emitting diode to apply forward voltage to the opposite surface and by observing the developed emission region distribution and/or by measuring the forward voltage current characteristics. CONSTITUTION:A probe 5 is brought into contact with the surface of an epitaxial layer 1 of an epitaxial wafer 3 of compound semiconductor light emitting diode which has a pn-jucntion to apply forward voltage to the opposite surface. The distribution of the developed emission region 7 is observed and/or the forward voltage current characteristics are measured. For instance, if there is no inner abnormal layer under the probe 5, a light emission region 7 is developed in a shape of a small disc immediately below the probe 5 and the voltage through pn-junction is low; on the contrary, if there is an inner abnormal layer 10 under the probe 5 and a thyristor construction or a high resistance layer is formed, current is hard to flow and an emission region 11 is developed in a ringed shape enclosing immediately below the probe 5 whereon there is no emission of light.
