Abstract
A FeFET and a method of its manufacture are provided, the FeFET having a ferroelectric whose film thickness (dr) is made small and so nanofine as to range in: 59 nm<dr<150 nm, without impairing the data retention property of not less than 10seconds and the data rewrite endurance property of not less than 10times, of those that have hitherto been developed, and the FeFET allowing a memory window of 0.40 V or more when a sweep amplitude of the gate voltage is not more than 3.3 V.
