  • Patent number: 9045653
    Abstract: Embodiments relate to printing features from an ink containing a material precursor. In some embodiments, the material includes an electrically active material, such as a semiconductor, a metal, or a combination thereof. In another embodiment, the material includes a dielectric. The embodiments provide improved printing process conditions that allow for more precise control of the shape, profile and dimensions of a printed line or other feature. The composition(s) and/or method(s) improve control of pinning by increasing the viscosity and mass loading of components in the ink. An exemplary method thus includes printing an ink comprising a material precursor and a solvent in a pattern on the substrate; precipitating the precursor in the pattern to form a pinning line; substantially evaporating the solvent to form a feature of the material precursor defined by the pinning line; and converting the material precursor to the patterned material.
