Abstract:
An embodiment of the present disclosure provides a method of processing a workpiece in which a plurality of holes are formed on a surface of the workpiece. The method includes a first sequence including a first process of forming a film with respect to an inner surface of each of the holes and a second process of isotropically etching the film. The first process includes a film forming process using a plasma CVD method, and the film contains silicon.

Claim (Index 3):
The method of  claim 1 , wherein in the second process, the film is isotropically etched by removing the film for each atomic layer by repeatedly executing a second sequence including:\n a third process of generating plasma of a first gas within a processing container of a plasma processing apparatus in which the workpiece is accommodated, and isotropically forming a mixed layer that includes an ion included in the plasma of the first gas in the atomic layer of the inner surface of the hole; a fourth process of purging a space within the processing container after executing the third process; a fifth process of generating plasma of a second gas within the processing container and removing the mixed layer by radicals included in the plasma of the second gas after executing the fourth process; and a sixth process of purging the space within the processing container after executing the fifth process, the first gas includes nitrogen, the second gas includes fluorine, and the plasma of the second gas generated in the fifth process includes the radials that remove the mixed layer including silicon nitride.
