Patent ID: 6881444

Claim:
A process for fabricating ultrathin multilayer films, the process comprising the steps of: introducing positive or negative charge or a material capable of hydrogen bonding to a substrate and placing said substrate on a spinner to pretreat said substrate; dropping a material (A) bindable with the material deposited onto the substrate, and spinning the substrate 2000 rpm to 6000 rpm for 4 to 200 seconds in a first coating step; dropping washing solvent onto the substrate after completion of the first coating and spinning the substrate at 2000 rpm to 6000 rpm for 4 to 200 sec to remove weakly-bound material (A) and form a thin film (A) in a first washing step; dropping another material (B) bindable with the material (A) coated onto the substrate and further coating it under the same conditions as for the first coating in a second coating step; and dropping washing solvent onto the substrate after completion of the second coating and spinning the substrate at 2000 rpm to 6000 rpm for 4 to 200 sec to remove weakly-bound material (B) and form a thin film (B) in a second washing step; wherein the coating and washing steps are more than once repeated.
