Abstract: PROBLEM TO BE SOLVED: To improve the step coverage of upper-layer wiring by forming a narrow deep hole which is controlled to have a tapered cross section through an interlayer insulating film. SOLUTION: At the etching of an interlayer insulating film 2 for forming a contact hole 8, a fixed amount of nitrogen gas is added in addition to fluorocarbon, one or more kinds of gases of the hydrogen substitution products of fluorocarbon, and argon gas as carrier gases. Consequently, the generating rate of a fluorine radical is decreased, and the reaction between tungsten wiring 1 constituting an underlying film and fluorine is accelerated at the etching, and accordingly, a sidewall protective film 4 composed of a fluorine compound is formed on the sidewall of the contact hole 8, resulting in a tapered contact hole 8. Consequently, the reliability of aluminum wiring 5 which is successively formed as upper-layer wiring is improved, because the step coverage of the wiring is improved.

Title: Paper-feeding mechanism for printer
Inventor: WAKABAYASHI TOMIO
IPC: B41J13/054
Filed: 1983-10-20
Abstract: PURPOSE:To enable to securely feed a paper even when a comparatively thick printing paper is used, by a construction wherein a plurality of feeding rollers pressed against the outer periphery of a platen are connected to each other by a rotation-transmitting means. CONSTITUTION:When a platen 34 is rotated after inserting the leading end of a printing paper 44 between the platen 34 and rear feeding rollers 50, the leading end tends to be clamped between the platen 34 and the rollers 50, but when the paper 44 is thick, the platen 34 and the rollers 50 are spaced from each other, resulting in that the rotation of the platen 34 is not transmitted directly to the rollers 50. However, since front feeding rollers 48 are pressed directly against the platen 34 with a sufficient pressure, the rotation of rollers 48 is transmitted to the rollers 50 through a belt 66 fitted between a roller shaft 52 and a roller shaft 54. Accordingly, the paper 44 is securely fed, and is clamped between the platen 34 and the front feeding rollers 48 by the further rotation of the platen 34, thereby enabling smooth feeding of paper.

Abstract: PURPOSE:To attain oxidation or nitriding at a high speed by setting an ion source at the place after a ferromagnetic material evaporating source within a vacuum tank, and supplying the oxigen or nitrogen gas at a low level of gas pressure to a ferromagnetic metallic thin film layer from the ion source. CONSTITUTION:A ferromagnetic material 9 is heated and evaporated by a ferromagnetic material evaporating source 8 set on the lower bottom of a vacuum tank 1 and opposite to a substrate 4. Thus a ferromagnetic metallic thin film layer on the substrate 4. Then ionized oxygen or nitrogen gas is supplied to the substrate 4 from an ion source set in the tank 1. The source 10 produces a plasma of the supplied gas by a normal cool cathode magnetron and then extracts only the ion as a beam with application of voltage. It is desirable for an ion current to have the 50mA (argon) performance with 0-4kV discharge volt- age, 0-1.0Amp magnet current and 0-7kV ion extraction voltage respectively. Such oxygen or nitrogen gas has high energy and is extracted into the tank 1 under a low level of gas pressure. Therefore, such gas enters the surface of the ferromagnetic metallic thin film layer at a high speed and high efficiency and with no loss of energy.
