Abstract
Methods are generally provided for sputtering thin films on individual substrates. Individual substrates can be conveyed into a vacuum chamber to draw a sputtering pressure that is less than about 50 mTorr. Then, the individual substrates can be conveyed into a sputtering chamber and past a planar magnetron continuously sputtering a target by an ionized gas at the sputtering pressure such that a thin film is formed on a surface of the individual substrate. The target is subjected to a high frequency power having a frequency from about 400 kHz to about 4 MHz at power levels of greater than about 1 kW. In one particular embodiment, the method can be generally directed to sputtering thin films on individual substrates defining a surface having a surface area of about 1000 cmto about 2500 cm.
