US 6162744 A Resumen
41. A method of forming a DRAM cell comprising:forming a first capacitor electrode over a substrate; forming a high K oxygen containing capacitor dielectric layer over the first capacitor electrode; first annealing the high K capacitor dielectric layer at a temperature of at least about 500� C. in a substantially non-oxidizing atmosphere; after the first annealing, second annealing the high K capacitor dielectric layer at a temperature of less than or equal to about 500� C. in an oxidizing atmosphere; forming a second capacitor electrode over the high K oxygen containing capacitor dielectric layer; providing a field effect transistor having a pair of source/drain regions, one of the source/drain regions being provided in electrical connection with the first capacitor electrode, the other of the source drain regions being provided in electrical connection with a bit line.
