A plasma equipment seasoning method. The seasoning method comprising the steps of measuring the ratio of optical emission intensity of silicon oxide (SiOx)-based chemical species to optical emission intensity of carbon fluoride compound (CFy)-based chemical species present in a process chamber of plasma equipment before operating the plasma equipment to perform a plasma process, determining whether the value of the measured optical emission intensity ratio is within a predetermined range of normal state or not, and, when reaction gas to be used in the plasma process is supplied into the process chamber based on the result of determination such that the value of the measured optical emission intensity ratio is within the predetermined range of normal state, seasoning the interior of the process chamber to change the ratio of components of the reaction gas, and thus, to change the optical emission intensity ratio.

The electrostatic chuck comprises a chuck base for supporting a wafer, a dielectric film mounted on the chuck base, the dielectric film having an electrode for supplying direct current voltage to provide an electrostatic force to fix the wafer, the electrode disposed in the dielectric film, and a cooling channel for supplying refrigerant to the dielectric film to control the temperature of the wafer. At least two first cooling channel parts are formed at the surface of the dielectric film corresponding to the edge part of the wafer such that the first cooling channel parts form concentric circles, second cooling channel parts formed at the surface of the dielectric film such that the first cooling channel parts are connected to each other through the second cooling channel parts, first through channels formed through the dielectric film for supplying the refrigerant to the first and second cooling channel parts, and a second through channel formed through the center of the dielectric film for supplying the refrigerant to the center of the wafer.

Provided are ASCON utilizing atomized slag as fine aggregates and a method for producing the same. More particularly, provided are ASCON composition that is improved in strength by substituting all or part of fine aggregates for atomized slag and a method for producing the same. ASCON composition includes coarse aggregates, fine aggregates, fillers, and asphalt. When the fine aggregates is 100 parts by weight, the fine aggregates include 0-70 parts by weight of atomized slag balls having a diameter of less than 5mm. Accordingly, it is possible to obtain the ASCON composition that has large strength and can greatly reduce a heating temperature in the mixing operation.
