摘要:
A ceramic susceptor with an embedded metal electrode. The metal electrode has multiple apertures, and the ceramic material is cross-linked through the apertures. An electrical connection to the electrode protects the electrode from the environment in the processing chamber. The ceramic may be aluminum nitride, and the metal electrode may be a mesh of molybdenum wires. To form the electrical connection, the susceptor may be heated until an eutectic forms between a conductive connector and the metal electrode. Alternately, a brazing material may be placed between the metal layer and a conductive connector.

Novel method of joining ceramics containing aluminum nitride and another member made of a metal or a ceramic is provided having an improved joining strength and a corrosion-resistant property by joining a first member made of a ceramics consisting of an aluminum compound. The second member is made of a ceramics or a metal, forming a metal film directly on a surface to be joined of the first member interposing a metallic joining material which is made of a different material from the metal film. The metallic joining material is between the metal film and the second member, and by heating at least the metallic joining material and the metal film in such an interposed state to form a joining layer made of the metallic joining material and an intermetallic compound between the first and second members, so as to join the two members.

A ceramic member-electric power supply connector coupling structure includes a ceramic member with a hole and is provided with a metallic member therein so as to be partially exposed to the hole. An electric power supply connector and a tubular atmosphere-shielding member are provided in the hole. Further, a stress-mitigating, low heat expansion conductor is provided inside the atmosphere-shielding member and the power supply connector is partially positioned therein. The atmosphere-shielding member is gas-tightly joined to the power supply connector, and the expansion conductor and the tubular atmosphere-shielding member are joined to the metallic member. The coupling structure has high heat and corrosion resistance, high joining strength, and remains highly conductive even at high temperature conditions in an oxidative or corrosive environment.

An electrostatic chuck includes: a base body; an electrode formed on the base body and generating coulomb force; and a dielectric layer formed on the base body and electrode, having a plurality of projections on a first main face on the side supporting a substrate attracted by the coulomb force, and supporting the substrate on the upper surfaces of these projections. The projections are arranged at substantially uniform intervals. The surface roughness (Ra) of the projection upper faces is 0.5 μm or smaller. The height of the projections is 5 to 20 μm. The relation A1/2×B2>200 is satisfied where A (number/100 cm2) is the number of the projections per unit area of 100 cm2 in the first main face, and B (μm) is the height of the projections.
