Abstract:
1. A plasma oxidation processing method comprising: generating plasma with an O( 1 D 2 ) radical density of 1×10 12 [cm −3 ] or more from a process gas containing O 2 gas and Ar gas inside a process chamber of a plasma processing apparatus; and performing an oxidation process on a surface of a target object by the plasma, wherein the plasma is generated from the process gas by microwaves supplied from a planar antenna including a plurality of slots into the process chamber, the microwaves have a power of 0.97 to 2.67 W/cm the plasma oxidation process uses a pressure of 1.33 to 334 Pa inside the process chamber, and the process gas has an oxygen ratio of 0.2 to 1%, which is represented by a ratio of the O
