  • Patent number: 6060836
    Abstract: A plasma generating apparatus has a plasma-generating vessel into which a gas is introduced. A coaxial line is inserted into the plasma-generating vessel. The coaxial line is insulated from the vessel with an insulator. The coaxial line has a central conductor and an outer conductor, to both of which microwave is supplied from a magnetron. That part of the central conductor which is located inside the plasma-generating vessel has, disposed therein, permanent magnets which form a cusp field. A seed plasma is formed around the permanent magnets by microwave discharge. A direct-current voltage is applied from a direct-voltage source between the outer conductor 24 and the plasma-generating vessel. Upon this application, electrons in the seed plasma move toward the inner wall of the plasma-generating vessel and are accelerated to ionize the gas. The ionized gas serves as seeds to cause arc discharge between the outer conductor and the plasma-generating vessel to generate a main plasma.

    Abstract: In a plasma-CVD method and apparatus, plasma is formed from a film material gas in a process chamber and, in the plasma, a film is deposited on a substrate disposed in the process chamber. Formation of the plasma from the material gas is performed by application of an rf-power prepared by effecting an amplitude modulation on a basic rf-power having a frequency in a range from 10 MHz to 200 MHz. A modulation frequency of the amplitude modulation is in a range from 1/1000 to 1/10 of the frequency of the basic rf-power. Alternatively, the rf-power is prepared by effecting on the basic rf-power a first amplitude modulation at a frequency in a range from 1/1000 to 1/10 of the frequency of the basic rf-power, and additionally effecting a second amplitude modulation on the modulated rf-power. A modulation frequency of the second amplitude modulation is in a range from 1/100 to 100 times the modulation frequency of the first amplitude modulation.

  • Patent number: 5501911
    Abstract: A copper film coated substrate includes a substrate and a copper film formed on a surface of the substrate. The copper film has an X-ray diffraction intensity of 2.0 cps/nm or more per unit film thickness at a crystal orientation (111) face of the copper film. A crystal orientation of a copper thin film is controlled by irradiating a surface of a substrate with inert gas ions before forming a copper thin film on the substrate by a physical vapor deposition process. A copper thin film is formed by irradiating a surface of a substrate with ions, and depositing a copper thin film on the irradiated substrate. In the ion irradiating step, an ion irradiation energy for a dosage of the irradiated ions is controlled, so that crystal is greatly grown to be orientated in a direction of copper (111) face with a less dosage of the irradiated ions.
