SnO2 doped Sb (ATO) thin films with Sb concentration of 0, 1, 5, 10 % a.t. were fabricated on glass substrate by spin coating method using metal-inorganic (SnCl4, SbCl3) or metal-organic (SnCl2(acac)2,Sb(acac)3) precursors. The ATO thin film fabricated using inorganic precussor has low uniformity resulting high resistivity. Contrary, with organic precursors, The ATO thin film fabricated has high uniformity. The 100 nm thickness of the film on glass substrate was received with two step spincoating, the transmittance > 87% and the lowest resistivity of ~ 2×10-3cm with Sb doping concentration Sb/(Sn+Sb) = 5%at.
