Filed: 2001-12-04
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method and system for selectively etching a thin film formed on a substrate and containing a high-permittivity material.  <P>SOLUTION: The vapor of aqueous hydrofluoric acid solution is introduced to the surface of a wafer W heated to a prescribed temperature by a hot plate 45 from a hydrofluoric acid vapor generating vessel 43. On the surface of the wafer W, a gate insulating film composed of the high-permittivity material is formed together with a silicon oxide film, and a polysilicon film etc. Since the temperature dependence of the etching rate of hydrofluoric acid in vapor- phase etching is extremely high, the gate insulating film formed on the wafer W can be well patterned by selectively removing the film without significantly damaging the silicon oxide film and polysilicon film by appropriately adjusting the temperature of the wafer W.  <P>COPYRIGHT: (C)2003,JPO
