    • A laser heating apparatus (20) for heating a thin film forming substrate (1) in a thin film manufacturing process is disclosed. The substrate (1) set in position in a vacuum chamber (101) of a film forming apparatus (100) is irradiated with a laser light and is thereby heated to a desired temperature. The laser light is guided to a region of the substrate (1) by means of an optical fiber (23), and the laser beams emanating from the outlet end of the optical fiber (23) is incident directly or indirectly via a reflecting mirror (33) on the substrate (1). The optical fiber (23) is sheathed with a jacket tube (24) whose interior is vacuum drawn. Using a laser light enables the arrangement to be used even in an oxidizing atmosphere and even an insulating substrate to be heated.
    • 公开了一种用于在薄膜制造工艺中加热薄膜形成基板(1)的激光加热装置(20)。 将成膜装置(100)的真空室(101)中的基板(1)照射激光,由此被加热到期望的温度。 激光通过光纤(23)被引导到基板(1)的区域,并且从光纤(23)的出口端发出的激光束直接或间接地通过反射镜( 33)放置在基板(1)上。 光纤(23)用内套真空抽吸的护套管(24)套管。 使用激光使得即使在氧化气氛中甚至是要加热的绝缘基板也可以使用这种布置。

    • An apparatus for generating plasma of helium mainly-contained gas added with halogen element using high-frequency energy which is applied between concentrically-arranged electrodes to conduct an etching treatment on a substrate with the thus-generated plasma, is equipped with a grounded electrode on the surface of the substrate, the grounded electrode serving to prevent electrification or charging of the substrate. A cylindrical insulator is provided between the electrodes so as to be contacted with the outside electrode, and a voltage applied between the central electrode and the cylindrical insulator is heightened by reducing the thickness of the cylindrical insulator or increasing the dielectric constant of the cylindrical insulator, so that low-temperature plasma is generated under atmospheric pressure using argon mainly-contained gas in a reaction space. Further, in a plasma generating apparatus for generating plasma with a pair of parallel electrodes, an insulator having high dielectric constant is provided in close contact with one of the electrodes, and gas mainly containing rare gas such as helium, argon or the like is supplied into the discharge space between the pair of parallel electrodes while the flow amount of the gas is controlled by a flow-amount controller, thereby inducing the gas to plasma under atmospheric pressure, and generating a sheet-shaped plasma.
