ABSTRACT:
A method of forming a thin film using a sputtering apparatus having a chamber, includes the steps of providing a target and a wafer in the chamber, and providing an inert gas to form atomized target material, a reactive etching gas for reacting with the target to form a molecular by-product, and a reactive sputter gas for reacting with the atomized target material and the molecular by-product to form a thin film on the wafer.
