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 15):
A method according to  claim 5 , further including executing a second sequence including the first step and the second step, and wherein:\n the second sequence is executed a plurality of times; and during each execution of the first sequence an amount by which the first region is etched is less than an amount by which the first region is etched during each execution of the second sequence.
