Abstract: The present invention provides a temperature control unit capable of efficiently controlling a temperature of a specific object with reduced risk of failure of electronic components due to leakage of a temperature control medium. The temperature control unit (1), which controls a temperature of a specific object, contains a temperature control medium, and a metal fiber sheet (50) that is formed with a space serving as a channel of the temperature control medium. The latent heat of evaporation of the temperature control medium is within the range of from 70 to 200 kJ/kg when the temperature control medium changes the state from a liquid state to a gaseous state. The volume expansion rate of the temperature control medium is at most 250 times when the temperature control medium changes the state from a liquid state to a gaseous state under atmospheric pressure.

Abstract: A radio-frequency antenna through which a high amount of current can be efficiently passed even at a radio-frequency level for plasma generation, as well as a plasma processing device utilizing the radio-frequency antenna. A radio-frequency antenna includes a metal fiber sheet. A plasma processing device includes: a vacuum container including a wall having an opening; a radio-frequency antenna including a metal fiber sheet and located at the opening; and a dielectric protection plate located closer to the interior of the vacuum container than the radio-frequency antenna and configured to close the opening in a gas-tight manner. The radio-frequency antenna including a metal fiber sheet has a larger surface area and a lower impedance to a radio-frequency current than a radio-frequency antenna including a metal plate having the same outer shape. Therefore, it allows a radio-frequency current commonly used for plasma generation to be more efficiently passed through in large amounts.
