Title: Electrostatic chuck
Inventor: KANAI MUNENORI
IPC: H01L21/68
Filed: 1986-10-13
Abstract: PURPOSE:To obtain large electrostatic force and to improve its responsiveness by causing stoichiometric compositions to be deficient in oxygen or nitrogen contained in high insulators of oxide and nitride series and mixing materials of conductors, semiconductors or low resistors in other materials of conductors, insulating films or high insulators that combine with the above elements; oxygen and nitrogen. CONSTITUTION:An insulating film 103 is formed on the surface of a holding plate 102 having a sheet electrode 100 on a ceramic substrate 101 and a positive voltage is impressed from a power source 104 to the sheet electrode. At this electrode, a low resistance insulating film where a volume specific resistance is less than 10<13>OMEGA.cm is used as the insulating film 103. Thus, when electron beam vaporization for Si is carried out using SiOx(x<2) at the insulating film 103, it may be as well to obtain SiOx having the desired film resistance by controlling a flow rate of oxygen in an atmosphere of oxygen or to use a resistance reducing material that is miscible with alumina; for example, an alumina film where ultra-perticulates of metal titanium are mixed and burned. Further, the existence of irregularities on the insulating film surface makes static capacity between the insulating film and sample face smaller and responsiveness of electrostatic force higher.

Then, an output signal of the element 54B is frequency divided by a frequency divider 66, then band-pass limited by a high-pass filter 67, and detected. This detected result is integrated by a low-pass filter 68, and a torque detection signal changed at its DC level in response to a frequency of the sine wave signal, i.e., the pedal power is detected. The torque can be detected without contact by detecting the resonance frequency changing according to the pedal power.
