    摘要: There is provided a means for uniformly controlling the in-plane temperature of a semiconductor wafer at high speed in a high heat input etching process. A refrigerant channel structure in a circular shape is formed in a sample stage. Due to a fact that a heat transfer coefficient of a refrigerant is largely changed from a refrigerant supply port to a refrigerant outlet port, the cross sections of the channel structure is structured so as to be increased from a first channel areas towards a second channel areas in order to make the heat transfer coefficient of the refrigerant constant in the refrigerant channel structure. Thereby, the heat transfer coefficient of the refrigerant is prevented from increasing by reducing the flow rate of the refrigerant at a dry degree area where the heat transfer coefficient of the refrigerant is increased. Further, the cross section of the channel structure is structured so as to be reduced from the second channel areas towards a third channel areas, and thereby the heat transfer coefficient of the refrigerant is prevented from decreasing. Accordingly, the heat transfer coefficient of the refrigerant can be uniformed in the channel structure.

    摘要: A substrate holder that forms a concavo-convex pattern on recording layers of both of front and back sides of a magnetic recording media is provided. The substrate holder includes an insulator member having a concave portion that holds the etching substrate and a through-hole formed just below the concave portion, and a conductive member having a convex portion that is engaged with the through-hole. A gap is defined between a front side of the convex portion and the bottom surface of the substrate in a state where the etching substrate is mounted on the concave portion, and a thickness of the gap is equal to or higher than 0.5 mm and equal to or lower than 1 mm, and a thickness of the insulator member is equal to or higher than 1 mm and equal to or lower than 15 mm.

    摘要: The present invention provides a temperature control unit for an electrostatic adsorption electrode that is capable of controlling the wafer temperature rapidly over a wide temperature range without affecting in-plane uniformity while high heat input etching is conducted with high wafer bias power applied. A refrigerant flow path provided in the electrostatic adsorption electrode serves as an evaporator. The refrigerant flow path is connected to a compressor, a condenser, and a first expansion valve to form a direct expansion type refrigeration cycle. A second expansion valve is installed between the electrostatic adsorption electrode and the compressor to adjust the flow rate of a refrigerant. This makes it possible to compress the refrigerant in the refrigerant flow path of the electrostatic adsorption electrode and adjust the wafer temperature to a high level by raising the refrigerant evaporation temperature. Further, a thin-walled cylindrical refrigerant flow path is employed so that the thin-walled cylinder is deformed only slightly by the refrigerant pressure.

    摘要: In a plasma processing apparatus, a check valve is installed close to a refrigerant inlet of a compressor. When performing maintenance of a sample stage, refrigerant collected from a refrigerant flow path is temporarily stored in a flow path section extending from an expansion valve to the check valve, making it possible to perform the maintenance without changing the amount of refrigerant in the refrigerating cycle. With a refrigerant storage tank, a refrigerant supply valve, and a refrigerant discharge valve included in the refrigerating cycle, when maintenance of the compressor, a condenser, or the expansion valve is performed, the refrigerant collected from the refrigerating cycle can be put in use again.
