  • Publication number: 20140004773
    Abstract: A processing end point detection method detects a timing of a processing end point (e.g., polishing stop, changing of polishing conditions) by calculating a characteristic value of a surface of a workpiece (an object of polishing) such as a substrate. This method includes producing a spectral waveform indicating a relationship between reflection intensities and wavelengths at a processing end point, with use of a reference workpiece or simulation calculation, based on the spectral waveform, selecting wavelengths of a local maximum value and a local minimum value of the reflection intensities, calculating the characteristic value with respect to a surface, to be processed, from reflection intensities at the selected wavelengths, setting a distinctive point of time variation of the characteristic value at a processing end point of the workpiece as the processing end point, and detecting the processing end point of the workpiece by detecting the distinctive point during processing of the workpiece.

  • Publication number: 20120056360
    Abstract: Producing a metal composite material by mixing hydrated ceramic particles, having water of crystallization that is bound within fine pores which have an average pore diameter of 1 nm or more and 80 nm or less, with a reinforcing material, the resulting mixture being sintered to form a preform which is then impregnated with a melt of an aluminum alloy and subjected to surface polishing. The ceramic particles, from which water of crystallization has been removed while the average pore diameter of the pores thereof is maintained, are dispersed uniformly, it is possible to obtain the metal composite material in which the ceramic particles that have fine pores are exposed on surfaces evenly in a stable manner by surface polishing that is conducted after the melt impregnation. The metal composite material can permit infiltration of a lubricating oil into the fine pores.

  • Patent number: 8052886
    Abstract: A fluorine-containing compound gas, e.g., SF6 gas, is converted into a plasma and a silicon portion of an object to be processed is etched by the plasma. At the same time, using a light source having a peak intensity of light in a wavelength range of light absorption of a reaction product, e.g., SiF4, for which, to be more precise, ranges from 9 ?m to 10 ?m, the light is irradiated onto a surface of an object to be processed from the light source. The SiF4 molecules absorb the light, become activated and gain kinetic energy to be used in gaining an easy escape from a hole. As a consequence, an amount (a partial pressure) of fluorine radicals (F*) used as an etchant is increased and an etching rate of a silicon is increased.
