Abstract:
A method for selectively etching a first region made of silicon oxide with respect to a second region made of silicon nitride or another material different from that of the first region. The method includes a first step for generating, in a processing container housing a workpiece to be treated, a plasma of a treatment gas including a fluorocarbon gas, an oxygen-containing gas, and an inert gas, and forming a deposit including fluorocarbon on the object to be treated; and a second step for etching the first region with radicals of the fluorocarbon included in the deposit. The first step and the second step are executed repeatedly.

Claim (Index 14):
The method of  claim 9 , further including executing a third sequence including the first step and the second step having different power conditions from each other, and\n high frequency bias power in the second step of the third sequence is higher than high frequency bias power in the first and second sequences.
