主权项 1. A semiconductor device manufacturing method, comprising: forming a gate insulating film containing a mixture of a hafnium oxide film and a zirconium oxide film on a workpiece having a source, a drain and a channel; and subjecting the gate insulating film to a crystallization heat treatment at a temperature of 600 degrees C. or less, wherein the content of the hafnium oxide film in the gate insulating film is 5 mol % to 30 mol % and the gate insulating film subjected to the crystallization heat treatment has a relative permittivity of 27 or more.
