摘要: A thin film of precursor for forming a layered superlattice material is applied to an integrated circuit substrate, then a strong oxidizing agent is applied at low temperature in a range of from 100° C. to 300° C. to the precursor thin film, thereby forming a metal oxide thin film. The strong oxidizing agent may be liquid or gaseous. An example of a liquid strong oxidizing agent is hydrogen peroxide. An example of a gaseous strong oxidizing agent is ozone. The metal oxide thin film is crystallized by annealing at elevated temperature in a range of from 500° C. to 700° C., preferably not exceeding 650° C., for a time period in a range of from 30 minutes to two hours. Annealing is conducted in an oxygen-containing atmosphere, preferably including water vapor. Treatment by ultraviolet (UV) radiation may precede annealing. RTP in a range of from 500° C. to 700° C. may precede annealing.

摘要: Metal organic precursor compounds are dissolved in an organic solvent to form a nonaqueous liquid precursor. The liquid precursor is applied to the inner envelope surface of a fluorescent lamp and heated to form a metal oxide thin film layer. The metal oxide thin film layer may be a conductor, a protective layer or provide other functions. The films have a thickness of from 20 nm to 500 nm. A conductive layer comprising tin-antimony oxide with niobium dopant may be fabricated to have a differential resistivity profile by selecting a combination of precursor composition and annealing temperatures.
