Abstract:
Generation of a deposit can be suppressed and high selectivity can be acquired when etching a first region made of silicon nitride selectively against a second region made of silicon oxide. A method includes preparing a processing target object having the first region and the second region within a chamber provided in a chamber main body of a plasma processing apparatus; generating plasma of a first gas including a gas containing hydrogen within the chamber to form a modified region by modifying a part of the first region with active species of the hydrogen; and generating plasma of a second gas including a gas containing fluorine within the chamber to remove the modified region with active species of the fluorine.

Claim (Index 14):
The method of  claim 1 ,\n wherein in the generating of the plasma of the first gas, a bias power is supplied to a stage configured to hold the processing target object mounted thereon, and a high frequency power is supplied to an inductively coupled plasma antenna.
