Title: Method for etching gallium nitride compound semiconductor layer and manufacture of semiconductor light emitting element using the same
Inventor: YANO HITOHISA
IPC: H01L21/306
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To etch the surface of a semiconductor layer perpendicularly to the surface without causing any such a trouble as mask peeling, etc., by forming an etching mask by forming an Ti film directly on the surface of the semiconductor layer and, after etching is completed, removing the mask by using a hydrofluoric acid solution. SOLUTION: After a semiconductor layer 2 is stacked on a substrate 1, a Ti film 3 is formed on the layer 2 and a photoresist film 4 is formed on the film 3 (a). The part to be etched of the semiconductor layer 2 is exposed by etching the Ti film 3 by the RIE method by using the photoresist film 4 as a mask (b). Then the semiconductor layer 2 is etched by the CAIBE method (c). Thereafter, the photoresist film 4 is removed with O2 plasma or an organic solvent, such as the acetone, etc., and the Ti film 3 is removed with a hydrofluoric acid. Therefore, the perpendicular etching can be performed by preventing the slump of etching shoulders.

Title: Detector for quantity of air
Inventor: SHIMOMURA SETSUHIRO
IPC: G01F1/00
Filed: 1981-08-10
Abstract: PURPOSE:To measure quantity of air easily with high accuracy by disposing a vane provided to an armature shaft of a DC motor in such a way as to intersect orthogonally with an air passage and measuring the electric current flowing in the DC motor. CONSTITUTION:A vane 5 is mounted to the armature shaft 51 of a DC motor 6 and is installed in an air passage 1. The motor 6 is connected to an electric power source 7-1 via a resistor 7-2, and the current output of the resistor 7-2 is inputted via an amplifier 7-3 and a D-A converter 7-4 to an operator 7-5. When the vane 5 rotates in the passage 1 in which air Q flows, the vane 5 is decelerated or accelerated by the flow, in accordance with which the current flowing through the motor 6 increases or decreases and pulsates. Since the difference between the max. value and min. value of the pulsation is proportional to the flow rate of air, the flow rate value of air is determined with the operator 7-5 from the current flowing through the motor 6.

Filed: 1995-05-25
Abstract: PURPOSE: To shorten the time required for removal processing and to prevent partial burning when an optional electrode film formed on a substrate of a liquid crystal cell is irradiated by a laser beam to be removed. CONSTITUTION: A laser head 26 of a laser oscillation means 24 is moved continuously along a prescribed moving path passing through on the electrode film of a removal subject. The laser oscillation means 24 is operated and the laser beam irradiates while the moving laser head 26 passes through the area of the electrode film of the removal subject. The operation of the laser oscillation means 24 is stopped while the moving laser head 26 passes through out of the area of the electrode film of the removal subject. Since only the electrode film of the removal subject is removed while continuously moving the laser head 26 along the moving path, the time required for removal processing is shortened, and the partial burning of the substrate is prevented.
