权利人:ASM IP HOLDING BV
摘要:Disclosed are methods and systems for forming a silicon-containing layer on a substrate. Further disclosed are composition and synthesis of silicon-containing precursor. The methods for forming a silicon-containing layer comprise executing a plurality of deposition cycles. A deposition cycle comprises a first precursor pulse that comprises exposing the substrate to a first precursor. The first precursor comprises a molecule comprising a P—Si bond. A deposition cycle further comprises a plasma pulse that comprises exposing the substrate to a plasma treatment. The plasma treatment comprises generating a plasma.

摘要:The present disclosure is related to the development of improved fertilizer for precision and sustainable agriculture. A method was developed wherein efficient NPK nanocomposite for plant nutrition was synthesized in a single step using aerosol science and technology concepts. Further a formulation was prepared by addition of ZnO, TiO 2 and other nanoparticles to the NPK nanocomposite. Also, an aerosol based foliar application technique was developed for the precise delivery of nanoparticles to the plants.
