NOVELTY - A dopant ink composition comprises dopant-silicate carrier formed by a dopant compound and a silicon-containing compound, where the dopant compound includes at least one alkyl group bonded to a Group 13 element or a Group 15 element, and the dopant compound and the silicon-containing compound are bonded together via a silicon-oxygen-dopant ion linkage; and at least one solvent.    USE - For forming doped regions in a semiconductor substrate (claimed). Also useful to fabricate variety semiconductor devices including, but not limited to, microelectronics, solar cells, displays, radio-frequency identification components, microelectromechanical systems devices, optical devices such as microlenses and medical devices.    ADVANTAGE - The dopant ink composition exhibits reduced out-diffusion, improved room temperature stability, and/or reliable inkjet jetting and accurate substrate pattern printing. Due to unique molecular structure of the dopant compounds used, the dopant ink composition prevents out-diffusion. Functionally, the structure of the dopant compound causes direct bonding to selective oligomers/polymers for film formation. The dopant-silicate carrier and solvent forms a non-aqueous mixture that is stable at room temperature for at least two weeks, without change in doping or process reliability. The composition is amenable to the use of a wide variety of solvents and additives for the adjustment of their doping performance and process windows. Due to their unique components, non-aqueous methods for fabricating the ink compositions do not rely on complicated synthetic processes and are comparatively less expensive.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for fabricating dopant ink composition for forming doped regions in a semiconductor substrate, involving providing a dopant compound including at least one alkyl group bonded to Group 13 element or Group 15 element; providing silicon-containing compound; mixing the dopant compound and the silicon-containing compound; and forming a dopant-silicate carrier including silicon-oxygen-dopant ion linkages.
