摘要： Various embodiments of the present invention are generally directed to an apparatus and method for low temperature physical vapor deposition (PVD) of an amorphous thin film layer of material onto a substrate. A PVD chamber is configured to support a substrate and has a cathode target with a layer of sputtering material thereon, an anode shield, and a magnetron assembly adjacent the target. A high impulse power magnetron sputtering (HiPIMS) power supply is coupled to the PVD chamber, the power supply having a charging circuit and a charge storage device. The power supply applies relatively high energy, low duty cycle pulses to the magnetron assembly to sputter, via self ionizing plasma, relatively low energy ions from the layer of sputtering material to deposit an amorphous thin film layer onto the substrate.
