Abstract (en)
[origin: WO9927151A1] A pulsed mode sputtering method and system for sputtering a material from a target onto a substrate in a sputtering deposition process to create thin films. The thin films are created by generating pulsed power from a power supply operated in pulsed mode. The power supply can be either a DC or RF power supply. The pulsed power is applied at full load during the power on portion and at a significantly reduced power (e.g., at 5 % of the full load power) during the power off portion. The pulsed power is applied to the target to sputter the target material onto the substrate at a reduced deposition rate to create a thin film on the substrate. Uniform films having thicknesses of less than 50 angstroms can be created using this pulsed mode deposition technique.
