Abstract: PURPOSE: A thin film depositing method using pulse plasma discharge is provided to be capable of effectively transforming reaction gas into plasma by using a pulse plasma production apparatus. CONSTITUTION: After transforming reaction gas A into the first plasma using a pulse plasma production apparatus, the first thin film is deposited at the upper portion of a wafer by flowing the first plasma into a thin film depositing apparatus. Then, the first plasma is exhausted by using purge gas. After transforming reaction gas B into the second plasma, the second thin film is deposited on the first thin film. Then, the second plasma is exhausted by using the purge gas. The pulse plasma production apparatus is provided with a power supply(21), a slide transformer(22) for decreasing the voltage supplied from the power supply, a high voltage transformer(23) for increasing the voltage supplied from the slide transformer, a load(25) for generating plasma by using the voltage supplied from the high voltage transformer, and a rotating spark gap switch(24) for connecting the high voltage transformer with the load.
