Abstract:
A process for production of a silica zeolite film on a semiconductor substrate, comprising:(a) combining a silica source selected from organic silica sources and inorganic silica sources with an organic hydroxide zeolite-structure-directing agent (SDA) and water to produce a zeolite synthesis composition containing the structure-directing agent, the silica source and water, in a molar ratio of x SDA: 1 silica source: y H2O, wherein the value of x is from about 0.2 to about 0.6 and the value of y is from about 100 to about 200; (b) contacting the substrate to be coated with the synthesis composition; and (c) heating the substrate and synthesis composition from step (b) to produce a silica zeolite film on the substrate.
