A variable compression ratio (VCR) apparatus with dual eccentric links is mounted on an engine, receives combustion power of a fuel-air mixture from a piston to rotate a crank shaft and changes a compression ratio of the fuel-air mixture. The VCR apparatus may include a connecting rod having a large end portion formed at one end thereof, which is connected to the crank shaft to receive a torque of the engine, and a small end portion formed at the other end thereof, the small end portion having a coupling hole formed therein, a pair of eccentric links having one ends coupled to the coupling hole from both sides facing each other and integrally rotating, and an eccentric rod connected to the other ends of the eccentric links and rotating within a predetermined angle range. The eccentric rod may be a pair of eccentric rods.

A plasma etching device is provided. The device includes a chamber, a cathode assembly, and an integral cathode liner. The chamber provides a plasma reaction space. The cathode assembly is positioned at an inner and central part of the chamber and supports a substrate. The integral cathode liner has a plurality of first vents and second vents formed at two levels and spaced apart respectively such that the uniformity of a gas flow and exhaust flow within the chamber is maintained, and is outer inserted to the cathode assembly and coupled at its lower end part to an inner surface of the chamber.

An apparatus for controlling the temperature of an electrostatic chuck is provided. The apparatus includes an electrostatic chuck including, as a fluid channel part for circulating a refrigerant, a first fluid channel formed in an outer circumference region of the internal and a second fluid channel formed in the whole internal region, and one or more chillers for supplying refrigerant controlled to different temperatures through the first fluid channel or the second fluid channel. The first and second fluid channels are formed in two up/down stages within the electrostatic chuck, thereby being independently capable of the temperatures of a center part and edge part of a wafer.
