摘要:
An etching chamber 1 incorporates a focus ring 9 so as to surround a semiconductor wafer W provided on a lower electrode 4. The plasma processor is provided with an electric potential control DC power supply 33 to control the electric potential of this focus ring 9, and so constituted that the lower electrode 4 is supplied with a DC voltage of, e.g., −400 to −600 V to control the electric potential of the focus ring 9. This constitution prevents surface arcing from developing along the surface of a substrate to be processed.

摘要:
A difference in etching rate between the coated silicon based insulating film and any of other kinds of silicon-based insulating films is reduced by using nitrogen gas as a part of the etching gas. Therefore, the underlying film may not be exposed to the etching gas for a long time, so that degradation or deterioration of the underlying film can be prevented.
摘要:
A plasma etching method includes the step of: etching a silicon layer of a target object by using a plasma generated from a processing gas containing a fluorocarbon gas, a hydrofluorocarbon gas, a rare gas and an O2 gas and by employing a patterned resist film as a mask. The target object includes the silicon layer whose main component is silicon and the patterned resist film formed over the silicon layer.
