  • Publication number: 20050238859
    Abstract: A metal member-buried ceramics article which can uniformalize adsorption force or adsorption force and distribution of temperature in plane, decrease pollution of a semiconductor wafer, and suppress warping of the whole body is provided. This article has a three layer structure comprising, between an upper layer 2 and a lower layer 3 composed of an AlN sintered body in the form of plate, an intermediate connecting layer 4 having a thickness of 0.5 to 10 mm composed of a sintered body of defatted AlN powder and a metal electrode 5 in contact with the inner surface of the upper layer or lower layer or a metal electrode in contact with the inner surface of the upper layer and a metal electric resistor in contact with the inner surface of the lower layer sandwiched between them, and has means for suppressing a stress remaining in sintering the defatted AlN powder.
