    摘要: An electrostatic chuck (ESC) for a wafer which directs a cooling gas to predetermined cooling areas of the wafer mounted on the chuck. Ring type sealing members divide the mounted wafer into the predetermined cooling areas and the predetermined cooling areas are independently supplied with a helium cooling gas. Each of the predetermined cooling areas is supplied through a separate conduit system wherein each conduit system has a single inlet into the chuck and a plurality of outlets which emit the helium gas into a respective one of the predetermined cooling areas. The plurality of outlets for each predetermined cooling area may communicate with the inlet via a respective plurality of branch conduits or via one or more branch conduits and a peripheral conduit which connects the plurality of outlets. By independently controlling the predetermined cooling areas, temperature variations on the wafer are effectively controlled.

    摘要: An ESC (Electrostatic Chuck) to chuck an object by electrostatic force, having an ESC main body supporting the object; a guide ring supported by the ESC main body and encircling the object; a dielectric material layer interposed between the guide ring and the ESC main body; a media gas supplier to supply a media gas to the guide ring; and a power supplier to supply power to the ESC main body. With this configuration, the ESC provides an apparatus to chuck a guide ring to an ESC main body, while maintaining the guide ring and an object, such as a wafer, at the same or similar temperature, thereby enhancing uniformity of the object during a semiconductor manufacturing process such as etching, deposition, or the like.
