Filed: 1992-12-01
Abstract: PURPOSE:To satisfactorily attract a wafer, to fix, convey and correct it by providing electrostatic electrodes on ceramics having a special range of a volume intrinsic resistance of a high temperature range to form an electrostatic chuck. CONSTITUTION:In an electrostatic chuck in which electrostatic electrodes 2 are buried in a ceramic body 1, a voltage 4 is applied to the electrode 2 and a material 3 to be attracted. Then, a volume intrinsic resistance of the body 1 is lowered to 10<8>-10<13>OMEGAcm in a temperature range of 250 deg.C or higher. Thus, a leakage current is increased to generate an attraction force, and a material 3 can be fixed to a surface 2a to be attracted. In this manner, a wafer can be satisfactorily attracted even at 250 deg.C or higher, a uniform film formation of the wafer and an increase in accuracy of a processing pattern are performed. A processing capacity of the wafer can be improved, and a contamination of the wafer is eliminated.

The diffusion layers 4 are layers in which the constituting elements (Ti and Fe in the substrate) have been diffused. The TiN thin film 3 and the diffusion layers 4 are formed e.g. by an ion plating method. When the primer Ti film 2 is coated on the surface of the substrate 1 and subsequently N2 gas is flowed for reacting the N2 with the Ti to coat the TiN thin film 3, the diffusion layers 4 are simultaneously formed. Thus, the reramic thin film suitably used for the sliding member of an operation mechanism is obtained.

Those pieces of binary logic information constitute binary series which increase by '1' as the angle increases or decreases, so one indicates the place of '1' and the other indicates the place of '2'. Therefore, whether the angle increases or decreases is displayed according to the phase relation between the binary logic information indicating the place of '2' and the output information of an exclusive OR means (exclusive OR circuit 4). Further, the angle is displayed based upon how many times the two pieces of binary logic information or the output information of the exclusive OR means varies in value.
