摘要： A fluorine-containing organic film having a relative dielectric constant of 4 or less is deposited on a semiconductor substrate using a material gas containing fluorocarbon as a main component in a reactor chamber of a plasma processing apparatus. During the deposition of the fluorine-containing organic film, a scavenger gas for scavenging fluorine constituting the fluorocarbon is mixed in the material gas. The proportion of the mixed scavenger gas in the material gas is changed to adjust the mechanical strength and relative dielectric constant of the fluorine-containing organic film.

摘要： The present invention discloses a dry etching method using a high density plasma, in which a fluorocarbon gas, whose fluorine to carbon ratio is less than 2:1, is used. Such arrangement provides improved etching selectivity ratios to the resist film. The adding of an inert gas and oxygen to such a fluorocarbon gas provides further improved etching selectivity ratios and improved etching rates.

摘要： A reactor is composed of a lower frame of a chamber, a quartz dome, an upper electrode, an 0 ring, and the like. A lower electrode and a substrate as a workpiece to be processed thereon are disposed in the reactor. The temperature of the quartz dome is maintained at a temperature of 180.degree. C. or higher by means of a heater. Fluorocarbon gas such as C.sub.2 F.sub.6 gas or C.sub.4 F.sub.8 gas is introduced into the reactor through a gas inlet and RF power from a first RF power source is applied to an antenna coil to produce a plasma and thereby etch an oxide film on the substrate. By heating the quartz dome to a high temperature, a deposit which hinders the release of oxygen from a wall face is prevented from being attached and the deposit on the bottom of the hole which causes an etch stop during processing is removed with oxygen. This prevents the etch stop during an etching process for forming a deep hole.
