20110006356	NON-VOLATILE MEMORY AND METHOD FOR FABRICATING THE SAME - A non-volatile memory is described, which includes gate structures, doped regions, second spacers and contact plugs. The gate structures are disposed on the substrate, each of which includes a control gate and a gate dielectric layer. The control gates are disposed on the substrate, and two first spacers are deployed at both sides of each control gate. The gate dielectric layers are disposed between the control gates and the substrate, respectively. Each of the doped regions is formed in the substrate between two adjacent gate structures. The second spacers are disposed on the sidewalls of the gate structures. The contact plugs are formed between two adjacent second spacers, respectively.	01-13-2011
20090148980	METHOD FOR FORMING PHASE-CHANGE MEMORY ELEMENT - A method for forming a phase-change memory element. The method includes providing a substrate with an electrode formed thereon; sequentially forming a conductive layer and a first dielectric layer on the substrate; forming a patterned photoresist layer on the first dielectric layer; subjecting the patterned photoresist layer to a trimming process, remaining a photoresist pillar; etching the first dielectric layer with the photoresist pillar as etching mask, remaining a dielectric pillar; comformally forming a first phase-change material layer on the conductive layer and the dielectric pillar to cover the top surface and side walls of the dielectric pillar; forming a second dielectric layer to cover the first phase-change material layer; subjecting to the second dielectric layer and the first phase-change material layer to a planarization until exposing the top surface of the dielectric pillar; and forming a second phase-change material layer on the second dielectric layer.	06-11-2009
