IPC: H01J27/16
Filed: 1989-04-13
Abstract: PURPOSE:To form a film of large area at high speed against a cylindrical or rectangular substrate by using the substrate also as one of inner conductors of a coaxial tube used as a transmission line for microwave, and inserting an insulating spacer into one part of a space between inner and outer conductors in a vacuum chamber. CONSTITUTION:Microwave generated at a microwave oscillating circuit 2 is transmitted through a square wave guiding tube 3, a square, coaxial convertor 4 and a coaxial tube 7, and is introduced into a vacuum chamber 10 through an airtight flange 8. When microwave with sufficient power is introduced into the chamber 10 microwave plasma is generated in a space between a substrate 1 and the wall of the vacuum chamber. The electric field strength of the microwave is in axial symmetry, for example, at the TEM mode of the coaxial tube. Moreover, since the electric field is distributed in inverse proportion to its radius, the electric field strength is maximum at near the outer face of the substrate 11. And uniform and high density plasma is generated in the vicinity of the outer face. Raw material gas is excited and decomposed by the plasma, and a uniform thin film is formed on the outer face of the substrate 11 at high speed even when the film has a large area.
