    摘要: A refrigeration system regulates the temperature of an electrostatic wafer chuck disposed in a process chamber. The refrigeration system includes a heat exchanger disposed in a heat exchange relationship with the electrostatic chuck, a refrigerator, a temperature sensor, and a temperature controller for controlling the refrigerator to cool the coolant withdrawn from the heat exchanger to a desired temperature in response to the temperature detected by the temperature sensor. The heat exchanger forms a coolant passageway inside the electrostatic chuck, and the refrigerator is disposed outside the process chamber. The temperature sensor is disposed within the body of the electrostatic chuck. The temperature of the electrostatic chuck can be regulated so as to be maintained nearly constant because the temperature used to control the cooling of the coolant is measured directly from the body of the electrostatic chuck.

    摘要: There is provided a semiconductor etching apparatus which removes particles remaining on the upper surface of an electro static chuck (ESC) during an etching process, thereby preventing a chucking force from decreasing and minimizing a leak of helium. To prevent a failure of the etching process due to a wafer chucking failure, by preventing polymers from falling down on the upper part of the ESC when a wafer is dechucked or transferred, the semiconductor etching apparatus comprises: an ESC selectively holding a wafer to be entered and positioned inside a chamber, and including a lower electrode part to which RF power is applied; parts positioned at a stepped portion of the ESC and respectively surrounding a side of the ESC; and a gas flow blocking part blocking a gas flow in a vacuum path formed between the ESC and the parts.

    摘要: An apparatus for matching the impedance of an RF generator to the impedance of an RF load, for use in manufacturing semiconductor devices by using a plasma. The apparatus includes a variable inductor coupled to a variable capacitor and an invariable capacitor, the variable inductor having two inductors coupled electrically with each other in series and disposed adjacent to each other. At least one of the two inductors is disposed movably to make the magnetic flux of the one inductor interfere with the magnetic flux of the other inductor, thereby to control the inductance of the variable inductor. In the case of a plasma enhanced semiconductor wafer processing system, the apparatus can reduce the time necessary to achieve an RF match between the RF generator and the RF load, thereby increasing the life of the apparatus.

    摘要: A method for generating a plasma. A gas flows along a flow path having the displacement identical to the lines of magnetic force of the main magnetic field, and high frequency alternating current is applied to the gas, thereby generating a gas plasma. For example, a gas is flowed through a pipe in a first direction. Electricity is conducted through the pipe in substantially the first direction. And a magnetic field is applied along a second direction (e.g., perpendicular to the first direction) to the gas flowing in the pipe such that a plasma is induced in the pipe.
