摘要: A device insulating film, a lower-layer platinum film, a ferroelectric film, an upper-layer platinum film, and a titanium film are sequentially formed on a semiconductor substrate in this order. On the titanium film, a photoresist mask is further formed in a desired pattern. The thickness of the titanium film is adjusted to be 1/10 or more of the total thickness of a multilayer film consisting of the upper-layer platinum film, the ferroelectric film, and the lower-layer platinum film. The titanium film is then subjected to dry etching and the photoresist film is removed by ashing process. The titanium film thus patterned is used as a mask in etching the upper-layer platinum film, the ferroelectric film, and the lower-layer platinum film by a dry-etching method using a plasma of a gas mixture of chlorine and oxygen in which the volume concentration of oxygen gas is adjusted to be 40%. During the dry-etching process, the titanium film is oxidized to provide a high etching selectivity. Subsequently, the titanium film is removed by dry etching using a plasma of chlorine gas.

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.
