METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE AND SEMICONDUCTOR MANUFACTURING APPARATUS

摘要

According to an embodiment, a method for manufacturing a semiconductor device is disclosed. The method includes: arranging a semiconductor substrate on a first electrode out of first and second electrodes arranged to be opposed to each other in a vacuum container; applying negative first pulse voltage and radio-frequency voltage to the first electrode, the negative first pulse voltage being superimposed with the radio-frequency voltage; applying negative second pulse voltage to the second electrode in an off period of the first pulse voltage; and processing the semiconductor substrate or a member on the semiconductor substrate by plasma formed between the first and second electrodes.
