Title: Etching uniformity examining method
Inventor: FUJII TERU
IPC: H01L21/3065
Filed: 1984-10-19
Abstract: PURPOSE:To make it possible to inspect uniformity of etching in-process, by sampling variable quantity of light reflected on the surface of a member to be etched at regular time intervals, and by converting the etching time, etching rate and CCD information into an etching depth. CONSTITUTION:Cylindrical lenses 13A, 13B and interfering filters 12A, 12B are arrayed in front of CCDs 14A, 14B respectively, so that one-dimensional informations averaged in parallel to and vertically to this paper-plane on the wafer 18 surface can be taken therein. The parallel and vertical informations are supplied therein through a half-mirror. For lighting for monitor, light from a light source 10 is focused by a lens 9, is reflected by a half-mirror and is supplied to the wafer 18. Outputs of the CCD 14A, 14B are fed to a data- processing apparatus 16, and an etching monitor controller 17 inspects uniformity ion the course of etching process and decides the final point to control the high frequency power source 4. Thus etching uniformity can be inspected in- process, and remarkable effects such as improvement of the precision, yield and efficiency can be attained in manufacture of LSI wafers.

Filed: 1989-08-28
Abstract: PURPOSE:To assure high speed operation with the safety of a maintenance person in a pit or on a cage by neutralizing a call by a cage call button of at least one side of the uppermost or lowermost floor and a hall call button when an inspection lamp switch is lighting-acted. CONSTITUTION:When an inspection lamp lighting switch TL is operated to light a lighting system for the inside of an elevating passage in a cage, a closed circuit is formed with a power source bus bar line P1, switch TL relay 43L, and power source terminal N, and energized with the relay 43L. Next since an ever-closed contact 43L1 is closed by the energization of the relay 43L, relays 5HA and 511 for the uppermost and lowermost floor cage call registerings are not energized even a power source bus bar line P3 is broken and the uppermost and lowermost floor cage call buttons CBA and CB1 are depressed. Consequently, the high speed travel of an elevator to the uppermost or lowermost floor is unable. Also since the line P3 is broken, a hall call register circuit is not formed, and the elevator can not be travelled even if the hall call button of any floor is depressed.

Abstract: PURPOSE:To stabilize the spraying action by making the energy to be lost by the flowing of a liq. through a discharge pipe smaller than the potential energy difference between a pressurized chamber and the end opened to the atmosphere in an ultrasonic spray device. CONSTITUTION:A discharge pipe 15 and a supply pipe 16 are connected to a pressurized chamber 6, and the end 17 opened to the atmosphere at the leading end of the discharge pipe 15 is made h1 lower than the center of the pressurized chamber 6. Meanwhile, the other end of the supply pipe 16 is connected to the first liq. tank 18, and the liq. surface 19 of the first liq. tank 18 is made h2 higher than the center of the pressurized chamber 6.
