High permittivity gate dielectric materials
WebMoreover, the low permittivity and high coercive field enables the adoption of the material for the realization of ferroelectric field-effect-transistors (FeFETs) that appear as an alternative for embedded charge trapping flash devices in particular. WebResearch into high permittivity candidate dielectrics has therefore proceeded with urgency over the past 3 years. In general, two approaches are possible. Industry would prefer the direct replacement of SiO2 as the gate dielectric, while making relatively few changes to the subsequent process conditions.
