摘要:
A ferroelectric semiconductor device (10) and a method of manufacturing the ferroelectric semiconductor device (10). The ferroelectric semiconductor device (10) has a layer (13) of ferroelectric material disposed on a semiconductor substrate (11) and a gate electrode (17) formed on a portion (26) of the layer (13) of ferroelectric material. The portion (26) of the layer (13) of ferroelectric material sandwiched between a semiconductor substrate (11) and a gate electrode (17) retains its ferroelectric activity. The portions (21, 22) of the layer (13) of ferroelectric material adjacent the portion (26) are damaged and thereby rendered ferroelectrically inactive. A source contact (31) and a drain contact (32) are formed through the damaged portions (21, 22) of the layer (13) of ferroelectric material.
