Title:
INSULATION COATING METHOD FOR METAL BASE, INSULATION COATED METAL BASE, AND SEMICONDUCTOR MANUFACTURING APPARATUS USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/135786
Kind Code:
A1
Abstract:
Disclosed is an insulation coating method for a metal base, which comprises a thermal spraying step (S1), an impregnation step (S2), and a beam irradiation step (S3). In the thermal spraying step (S1), a first insulation coating film is formed by thermally spraying a first meal oxide to the surface of a metal base. In the impregnation step (S2), pores formed in the surface of the first insulation coating film are impregnated with a sol that contains, as a dispersoid, a metal oxide, a hydrate of a metal oxide, or a metal hydroxide. In the beam irradiation step (S3), a second insulation coating film that is composed of a second metal oxide is formed by irradiating the first insulation coating film and the sol with a high energy beam after the impregnation step (S2).
