Abstract
A ferroelectric semiconductor device (10) and a method of manufacturing the ferroelectric semiconductor device (10). The ferroelectric semiconductor device (10) is manufactured from a substrate (11) that has a layer (14) of ferroelectric material sandwiched between a substrate (13) and a layer (16) of silicon. A gate structure (24) is formed on the layer (16) of silicon. A source region is formed in a portion of the layer (16) of silicon adjacent one side of the gate structure (24) and a drain region is formed in a portion of the layer (16) of silicon adjacent an opposing side of the gate structure (24).
