In this study, we clarify the heretofore unrecognized origin of limited device performance in polymeric mold soft-patterned oxide transistors, with a model experiment based on the micro molding in capillary (MIMIC) method. In order to elucidate the chemical influence of precursor solutions, three kinds of representative precursor solutions, which undergo the characteristic synthetic pathways of a conventional sol–gel reaction, combustion chemistry reaction, and chemical additive mediated reaction, are employed. Through the comparative study in terms of device performance, in conjunction with the spectroscopic, microscopic, and rheological analyses, it is suggested that the gradual solvent evaporation in structurally confined polymeric molds triggers the additional sluggish chemical reaction unlike the case of evaporation free, semi-solid involved other patterning methodologies, resulting in the significant degradation of device performance. |
