Patent number: 7253053Abstract: The invention includes methods of forming circuit devices. A metal-containing material comprising a thickness of no more than 20 ? (or alternatively comprising a thickness resulting from no more than 70 ALD cycles) is formed between conductively-doped silicon and a dielectric layer. The conductively-doped silicon can be n-type silicon and the dielectric layer can be a high-k dielectric material. The metal-containing material can be formed directly on the dielectric layer, and the conductively-doped silicon can be formed directly on the metal-containing material. The circuit device can be a capacitor construction or a transistor construction. If the circuit device is a transistor construction, such can be incorporated into a CMOS assembly. Various devices of the present invention can be incorporated into memory constructions, and can be incorporated into electronic systems.Type: GrantFiled: January 13, 2004Date of Patent: August 7, 2007Assignee: Micron Technology, Inc.Inventors: Denise M.

Patent number: 7153736Abstract: A method of forming a capacitor includes forming first capacitor electrode material over a semiconductor substrate. A silicon nitride comprising layer is formed over the first capacitor electrode material. The semiconductor substrate with silicon nitride comprising layer is provided within a chamber. An oxygen comprising plasma is generated remote from the chamber. The remote plasma generated oxygen is fed to the semiconductor substrate within the chamber at a substrate temperature of no greater than 750° C. effective to form a silicon oxide comprising layer over the silicon nitride comprising layer. After the feeding, a second capacitor electrode material is formed over the silicon oxide comprising layer. Methods of forming capacitor dielectric layers are also disclosed.Type: GrantFiled: February 13, 2004Date of Patent: December 26, 2006Assignee: Micron Technology, Inc.Inventors: Denise M.
