Ceramic heater

A ceramic heater includes: a ceramic plate which is provided with a wafer placement surface on an upper surface and in which a heating resistor is internally embedded; a ceramic tubular shaft with an upper end bonded to a lower surface of the plate; and power feeding members which penetrate a peripheral wall part of the tubular shaft in a vertical direction, and are electrically connected to the heating resistor. The power feeding members are embedded in the peripheral wall part of the tubular shaft, and are in tight contact with a ceramic material of the tubular shaft.

A member for a semiconductor manufacturing apparatus includes a ceramic disc incorporating an electrode and a ceramic cylindrical shaft supporting the disc. The disc and the shaft are integrally formed and mutually have no bonding interface. The disc has a surface with which the shaft is integrated. The surface has a region inside the shaft and a region outside the shaft. The region inside the shaft is recessed by one step with respect to the region outside the shaft and has an electrode exposure hole through which the electrode is exposed.

A ceramic heater includes a ceramic plate. An outer-peripheral-side resistance heating element is disposed in an outer peripheral zone of the ceramic plate. A wire line extends from each of a pair of terminals disposed in a central portion of the ceramic plate toward the outer peripheral zone, and a portion of the wire line close to the outer peripheral zone is a linear portion. A connection terminal is a conductive member connecting between the wire line and the outer-peripheral-side resistance heating element, and includes a first hole into which the linear portion of the wire line is inserted and a second hole into which an end portion of the outer-peripheral-side resistance heating element is inserted.

A wafer mounting table includes a first electrode and a second electrode buried inside of a ceramic substrate having a wafer mounting surface so as to be parallel to the wafer mounting surface with the first electrode closer to the wafer mounting surface than the second electrode. The wafer mounting table includes a conductive section that electrically conducts the first electrode and the second electrode. The conductive section is such that a plurality of circular members comprised of plate-shaped metal meshes parallel to the wafer mounting surface are stacked between the first electrode and the second electrode.

In a step (a), a ceramic substrate, a brazing material including a metal having a large thermal expansion coefficient, a porous body having a smaller thermal expansion coefficient than the brazing material, and a feeding terminal are placed on a joint surface in such a way that a joint surface of the feeding terminal faces a joint surface of the ceramic substrate. In a step (b), the brazing material is fused to allow the brazing material to penetrate into the pores of the porous body. In this manner, a joint layer containing the brazing material and the porous body is formed, and the joint surface of the ceramic substrate and the joint surface of the feeding terminal are joined to each other through the joint layer.
