Abstract
A precursor composition for the deposition and formation of an electrical feature such as a conductive feature. The precursor composition advantageously has a viscosity of at least about 1000 centipoise and can be deposited by screen printing. The precursor composition also has a low conversion temperature, enabling the deposition and conversion to an electrical feature on low temperature substrates. A particularly preferred precursor composition includes silver and/or copper metal for the formation of highly conductive features.
