Lithographic patterning of benzoylacetone modified SnO2 and SnO2 : Sb thin films
The synthesis of directly UV-photopatternable pure and antimony-doped organo-tin materials is presented. UV photopatternability has been achieved by using the synthesized benzoylacetone modified tin and antimony 2-isopropoxyethoxides. Photopatterned pure and antimony-doped organo-tin films are crystallized by thermal annealing in order to obtain conductive SnO2 and Sb:SnO2 thin films. The molar ratio between benzoylacetone and metal alkoxides has to be 2 in order to obtain crack-free, good-quality structures. The effects of UV irradiation,. increasing antimony doping level and benzoylacetone concentration on the electrical properties of the single-layered films are analyzed. The highest obtained conductivity was 20 S/cm. Benzoylacetone concentration and UV irradiation has only a negligible effect on the film electrical conductivities. (C) 2003 Elsevier B.V.
