Abstract

A ferroelectric semiconductor device (10) and a method of manufacturing the ferroelectric semiconductor device (10). The ferroelectric semiconductor device (10) has a layer (15) of ferroelectric material disposed on a semiconductor substrate (11) and a gate structure (27) formed on the semiconductor substrate (11). A source region (23) and a drain region (24) are formed on the semiconductor substrate such that the source region (23) and the drain region (24) are laterally spaced apart from the gate structure (27).
