摘要:
A thin aluminum film 3 is formed on the top surface of a substrate 2, 1. Selected areas of the aluminum film are irradiated by an oxygen ion beam 6 to form implanted regions 7. The surface is then plasma etched, with the oxygen ion implanted regions serving as a mask to thereby prevent the removal of the underlying areas of the aluminum film.
摘要:
Ions of a metal which becomes passive under the presence of oxygen with regard to plasma etching are implanted into selected portions of the surface of a workpiece, after which the workpiece is subjected to plasma etching with a reaction gas mixed with oxygen, whereby that layer which has been rendered passive acts as a mask, and an etched pattern is formed.
摘要:
A dry etching device is provided in which on at least one portion of the path of etchant movement from the plasma production region to the etching workpiece a resin coating containing atoms or molecules of the same type as the chemically active atoms or molecules which constitute the etchant, is formed.
摘要:
A thin film of a metal which is capable of oxidation and sublimation is formed on a major surface of a semiconductor substrate, and a portion of a major surface of the thin metallic film is irradiated with an oxygen ion beam to convert a portion of the thin metallic film to an oxide, and subsequently the thin metallic film is heat treated to remove the oxide by sublimation, whereby electrodes or wiring for a semiconductor integrated circuit are formed by the remaining thin metallic film.
摘要:
A nitride film is formed on a main surface of a semiconductor substrate by plasma CVD process and an oxygen-containing layer is formed on the nitride film and an aluminum-containing film is further formed on the oxygen-containing layer.
摘要:
A plasma treating apparatus includes: an air-core coil for generating a static magnetic field which is axially uniform and a high-frequency waveguide for generating a high-frequency electromagnetic field which is irregular in the axial direction of the air-core coil. A plasma generating glass tube is disposed in the high-frequency waveguide and adapted to be supplied with a gas and a plasma reaction bath held under a vacuum for receiving the plasma flow which is generated axially in the glass tube. A substrate platform is disposed in the reaction bath for supporting a substrate to be treated at a right angle with respect to the plasma flow. There is also included a magnetic field generating coil disposed outside of said reaction bath for shaping the plasma.
摘要:
In a delay failure test circuit, a delay failure test between two clock domains among a plurality of clock domains having different operation clock rates is performed. The delay failure test circuit inputs, to a first clock domain, a clock signal having only a launch edge for transferring data from the first clock domain to a second clock domain, and to input, to the second clock domain, a clock signal having only a capture edge for capturing the data.
摘要:
The present invention provides a glow plug capable of preventing a deformation or eccentricity of the coil, thereby improving a durability of the coil and preventing a variation in temperature-rising characteristic. Also, the present invention provides a method for manufacturing the glow plug.
