摘要
A method of forming a PCMO thin film in a RRAM device includes preparing a substrate; depositing a metal barrier layer on the substrate; forming a bottom electrode on the barrier layer; spin-coating a layer of Pri-xCaxMnO3 (PCMO) on the bottom electrode using a PCMO precursor; baking the PCMO thin film in one or more baking steps; annealing the PCMO thin film in a first annealing step after each spin-coating step; repeating the spin-coating step, the baking step and the first annealing step until the PCMO thin film has a desired thickness; annealing the PCMO thin film in a second annealing step, thereby producing a PCMO thin film having a crystalline structure of Pr1-xCaxMnO3, where 0.2=X=0.5; depositing a top electrode; patterning the top electrode; and completing the RRAM device.
