Apparatus for wafer treatment for the manufacture of semiconductor devices

摘要

An apparatus is provided for wafer treatment during the manufacture of semiconductor devices. The apparatus for wafer treatment includes a shaft, a chuck supported by the shaft for holding a wafer to be treated, a solution nozzle for supplying a treatment solution for wafer treatment onto the wafer, a gas supplier for supplying a gas to the back side of the wafer, and a heater for heating the gas supplied to the back side of the wafer. The use of this apparatus improves the uniformity of a treatment process such as an etching process or a cleaning process by minimizing the temperature changes of the treatment solution supplied onto the wafer mounted on the spin chuck of the apparatus during the wafer treatment process.
