摘要:
Improving the resistance of members and parts disposed inside of vessels such as semiconductor processing devices for conducting plasma etching treatment in a strong corrosive environment.A ceramic coating member for a semiconductor processing apparatus comprises a porous layer made of an oxide of an element in Group IIIa of the Periodic Table coated directly or through an undercoat on the surface of the substrate of a metal or non-metal and a secondary recrystallized layer of the oxide formed on the porous layer through an irradiation treatment of a high energy such as electron beam and laser beam.

A disk brake has a mount and a pad. The pad has a guide portion and outer and inner push bearing portions on a disk rotor rotation outlet side. The mount has a support portion to support the guide portion movably in a rotor axial direction. The outer and inner push bearing portions are provided on each position outwardly or inwardly of the rotor rotation outlet side guide portion in the radial direction of the rotor, and project toward the mount in the radial direction of the rotor to abut against the mount. The outer push bearing portion has an abutment surface to abut against the mount on a tangent to an outer peripheral side in a central position of the outer peripheral side of a friction surface of the pad radially outwardly in the radial direction of the rotor, or in a position outwardly of the tangent.

It is to propose an internal member for a plasma treating vessel having excellent resistances to chemical corrosion and plasma erosion under an environment containing a halogen gas and an advantageous method of producing the same, which is a member formed by covering a surface of a substrate with a multilayer composite layer consisting of a metal coating formed as an undercoat, Al2O3 film formed on the undercoat as a middle layer and Y2O3 sprayed coating formed on the middle layer as a top coat.

An electrostatic chuck member includes a metal substrate, an undercoat of a metallic spray-coated layer and a topcoat of Al.sub.2 O.sub.3 TiO.sub.2 based spray-coated layer containing a Ti.sub.n O.sub.2n-1, where n=1-9, compound. The electrostatic chuck member has a large volume resistivity, a small scattering, and the quality is stable. A method for making the electrostatic chuck member includes subjecting a metal substrate to a blast treatment, spray-coating a metallic undercoat on a surface of the metal substrate, and spray-coating Al.sub.2 O.sub.3 TiO.sub.2 on to the metallic undercoat to form a Al.sub.2 O.sub.3 -TiO.sub.2 based layer in which at least a portion of the TiO.sub.2 is changed into Ti.sub.n O.sub.2, where n=1-9.

摘要:
Thermally sprayed coatings made from carbides of metals having greater carbon affinity than Cr in the presence of free carbon, or thermally sprayed coatings made from carbides of metals having smaller carbon affinity than Cr are heat treated in a chromium halide containing atmosphere which also contains hydrogen gas, whereby activated metallic Cr is precipitated in a fine particulate form, which is allowed to act on the thermally sprayed coatings, whereupon a Cr.sub.23 C.sub.6 -form carbide is created not only on the coating surface but also in its interior, particularly within pores, to form a modified layer, thereby compositing the thermally sprayed coatings.
