摘要:
A method of fabricating a ferroelectric capacitor is disclosed. The method comprises decreasing a reduction in a bottom electrode material during formation of the ferroelectric dielectric portion of the capacitor. The method comprises forming an oxygen doped iridium layer and forming a ferroelectric dielectric layer thereover. During the formation of the ferroelectric, the oxygen doped iridium layer converts to an iridium oxide layer.

A method of fabricating a ferroelectric capacitor is disclosed. The method comprises the patterning of a top electrode layer and a dielectric layer to form a capacitor stack structure having sidewalls associated therewith. Prior to patterning the bottom electrode layer, a protective film is formed on the sidewalls of the capacitor stack structure in order to protect the dielectric material from conductive contaminants associated with a subsequent patterning of the bottom electrode layer.

摘要:
A method for simultaneously producing areas of paraelectric states and areas of ferroelectric states on a single thin film layer, thereby reducing the number of processing steps required to produce integrated chips containing both standard capacitors and non-volatile memory devices from the number of steps needed using the conventional approach. A device containing both ferroelectric capacitors and non-ferroelectric capacitors using a single thin film as the dielectric.
