Abstract

The instant disclosure provides a self-adsorbed catalyst composition, a method for preparing the self-adsorbed catalyst composition and a method for manufacturing an electroless plating substrate. The self-adsorbed catalyst composition includes colloidal nanoparticles and a silane compound. The colloidal nanoparticles include palladium nanoparticles and capping agents enclosing the palladium nanoparticles. The silane compound has at least an amino group, and an interaction is established between the amino group of the silane compound and the colloidal nanoparticle.

First claim

What is claimed is:

1. A self-adsorbed catalyst composition for electroless plating process, comprising:
a colloidal nanoparticle including a palladium nanoparticle and a capping agent enclosing the palladium nanoparticle; and
a silane compound having at least an amino group;
wherein the silane compound interacts with the colloidal nanoparticle through the amino group;
wherein the colloid nanoparticle has a particle size ranging from 5 to 10 nanometers.

2. The self-adsorbed catalyst composition according to claim 1 , wherein the capping agent is selected from the group consisting of polyethamine capped by trimethoxysilyl, polyvinyl alcohol, polyvinylpyrrolidone, polyacrylic acid and any combination thereof.

3. The self-adsorbed catalyst composition according to claim 2 , wherein the capping agent is a polymer having a molecular weight ranging from 5,000 to 10,000.

4. The self-adsorbed catalyst composition according to claim 1 , wherein the silane compound has 1 to 3 amino groups.

5. The self-adsorbed catalyst composition according to claim 1 , wherein the silane compound is selected from the group consisting of:
(3-aminopropyl)triethoxysilane, N-aminoethyl-3-(3-aminopropyl)triethoxysilane,
N-(6-aminohexyl) aminomethyltriethoxysilane,
3-[2-(2-aminoethylamino)ethylamino]propyl-trimethoxysilane,
N-(2-aminoethyl-3-aminopropyl)trimethoxysilane and any combination thereof.
