Claim Text:
1. A method of fabricating a transistor device comprising a thin film semiconductor component comprising indium gallium zinc oxide (IGZO), the method comprising: depositing a thin film from a nanomaterial dispersion comprising a semiconducting metal oxide nanomaterial in a solvent or solvent mixture and a binder composition comprising an indium salt, a gallium salt, and a zinc salt in a solvent or solvent mixture, wherein the indium salt, the gallium salt, and the zinc salt independently comprise either an oxidizing anion or a fuel anion, provided that (a) if none of the indium salt, the gallium salt and the zinc salt comprises a fuel anion, then the binder composition further comprises either a fuel or an ammonium salt comprising a fuel anion, and (b) if none of the indium salt, the gallium salt and the zinc salt comprises an oxidizing anion, then the binder composition further comprises either an acid comprising an oxidizing anion or an inorganic salt comprising an oxidizing anion, wherein: and fuel anions; and annealing the thin film at a temperature of less than or about 350° C. to initiate a combustion reaction between the oxidizing anions and the fuel and fuel anions, thereby forming a thin film semiconductor component comprising IGZO and converting the fuel and fuel anions into CO
