Patent ID: 11127590

Abstract:
A method for forming a high-k oxide includes forming a nanofog of Al2O3 nanoparticles and conducting subsequent ALD deposition of a dielectric on the nanofog. A nanofog oxide is adhered to an inert 2D or 3D surface, the nano oxide consisting essentially of sub 1 nm Al2O3 nanoparticles. Additional oxide layers can be formed on the nanofog. Examples are from the group of selected from the group consisting of ZrO2, HfZrO2, silicon or other doped HfO2 or ZrO2, ZrTiO2, HfTiO2, La2O3, Y2O3, Ga2O3, GdGaOx, and alloys thereof, including the ferroelectric phases of HfZrO2, silicon or other doped HfO2 or ZrO2.
