    Abstract: PURPOSE: A semiconductor device manufacturing method and a plasma etching device are provided to include a gas which is proceeding etching of a silicon dioxide film among a process gas, thereby eliminating degradation of an etching rate. CONSTITUTION: A pre-etched film formed in a substrate(W) which is included in a process chamber(1) is etched. A process gas comprised of a mixing gas of predetermined plural kinds of gases in the process chamber is supplied. A process of a first cycle comprised of a first process and second process is repeated at least more than three times consecutively by keeping the plasma created in the process chamber during the process. A flow rate of at least one kind of a gas among plural kinds of gases is a first flow rate during a first hour in the first process. A flow rate different to the first flow rate during a second hour is a second flow rate in the second process.

    Abstract: An etching method and a readable computer storage medium storing program for controlling same are provided to etch an etching target layer according to a predetermined pattern width by adjusting a pattern width of a mask layer. A first process is performed to deposit plasma reaction products on sidewalls of pre-patterned mask layer(212-1,212-2) and increase pattern widths of the pre-patterned mask layer. A second process is performed to etch an etching target layer by using the pre-patterned mask layer as a mask having the increased pattern widths. The second process is performed by etching the etching target layer while reducing the pattern widths of the mask layer by etching the sidewalls of the pre-patterned mask layer.
