Patent ID: 8202808

Claim:
A method for forming a strontium titanate film, comprising: a. applying between 50 and 200 pre-saturation pulses without a pulse of an oxidant between the pulses of a Sr-precursor to a substrate, wherein the substrate comprises a conductive layer; b. forming a Sr-containing and Ti-containing film on the substrate after applying the pulses by i. forming an SrO film from one or more SrO unit films; ii. forming a TiO 2 film from one or more TiO 2 unit films over the previously formed SrO film; iii. forming one or more SrO unit films over the previously formed TiO 2 film if the combined total thickness of all previously formed SrO films and all previously formed TiO 2 films has not reached a desired value; iv. forming one or more TiO 2 unit films over the previously formed SrO film if the combined total thickness of all previously formed SrO films and all previously formed TiO 2 films has not reached a desired value; v. repeating steps iii) and iv); and c. annealing the Sr-containing and Ti-containing film.
