Abstract
A non-catalytic palladium precursor composition is disclosed, including a palladium salt and an organoamine, wherein the composition is substantially free of water. The composition permits the use of solution processing methods to form a palladium layer on a wide variety of substrates, including in a pattern to form circuitry or pathways for electronic devices.
Claims25
A non-catalytic palladium precursor composition, comprising starting ingredients including a palladium salt and an organoamine, wherein the composition is substantially free of a reducing agent and the composition does not contact another composition including the reducing agent;
- and
- wherein the organoamine is a water immiscible monoamine selected from the group consisting of octylamine, nonylamine, decylamine, undecylamine, dodecylamine, tridecylamine, tetradecylamine, hexadecylamine, dipentylamine, dihexylamine, diheptylamine, dioctylamine, dinonylamine, didecylamine, propylpentylamine, butylpentylamine, tributylamine, and trihexylamine;
- wherein the total number of carbon atoms in the palladium salt and the organoamine combined is at least 12;
- and
- wherein at least a portion of the palladium salt and the organoamine form an amorphous palladium organoamine complex.
A process for forming a conductive palladium layer on a substrate, comprising:
- receiving a palladium precursor composition that comprises starting ingredients including a palladium salt and an organoamine, wherein the composition is substantially free of reducing agent;
- solution depositing the palladium precursor composition upon the substrate;
- and
- heating the palladium precursor composition to form the conductive palladium layer;
- wherein the organoamine is a water immiscible monoamine selected from the group consisting of octylamine, nonylamine, and decylamine;
- wherein the total number of carbon atoms in the palladium salt and the organoamine combined is at least 12;
- and
- wherein at least a portion of the palladium salt and the organoamine form an amorphous palladium organoamine complex.
A non-catalytic palladium precursor composition comprising an amorphous palladium organoamine complex, wherein the composition is substantially free of water;
- and
- wherein the organoamine is a water immiscible primary monoamine selected from the group consisting of octylamine, nonylamine, decylamine, undecylamine, dodecylamine, tridecylamine, tetradecylamine, and hexadecylamine;
- and
- wherein the total number of carbon atoms in the palladium salt and the organoamine combined is at least 12.
A non-catalytic palladium precursor composition, comprising starting ingredients including a palladium salt and an organoamine, wherein the organoamine functions as a solvent;
- wherein the palladium salt is palladium acetate;
- wherein the organoamine is a water immiscible primary monoamine selected from the group consisting of octylamine, nonylamine, and decylamine;
- and
- wherein at least a portion of the palladium salt and the organoamine form an amorphous palladium organoamine complex.
