Samsung patents capacitor design using doped metal oxides
Samsung describes a method for building a capacitor, a component that stores electrical charge, by creating a lower electrode from a specific metal oxide mixed with other metals. The filing details how to layer a dielectric material and an upper electrode onto the sides of this base structure to form the final component.
In the filing’s own words
A capacitor structure includes a lower electrode structure disposed on a substrate, including an oxide of a first metal having 4 valence electrons, and being doped with a second metal having 3, 5, 6, or 7 valence electrons, a dielectric pattern disposed on a sidewall of the lower electrode structure, and an upper electrode disposed on a sidewall of the dielectric pattern.
What exactly they claim (claim 1)
1. A method of forming a capacitor structure, the method comprising: forming a lower electrode structure disposed on a substrate, the lower electrode structure including an oxide of a first metal having 4 valence electrons and being doped with a second metal having 3, 5, 6, or 7 valence electrons; forming a dielectric pattern disposed on a sidewall of the lower electrode structure; and forming an upper electrode disposed on a sidewall of the dielectric pattern.
