摘要: A method of sputtering to deposit a target material onto substrate includes supplying an ionized gas the and material. first DC bias voltage having polarity opposite that is applied attract ions theretoward. second intermittently reduce ion accumulation thereon. Related apparatus methods fabricating phase-changeable memory devices are also discussed.
