Selective metallization on glass is widely used in the production of printed circuit boards ( PCB), display panels and solar cells. Selective masking and etching steps are used in the traditional photolithographic processes to create the regions of metallization on non-conducting substrates ; however, these processes require high-cost facilities and complicated operations. To address these issues, a non-photolithographic process to form metal patterns on glass was proposed and put into practice, which combines self-assembly of aminosilane, desktop inkjet printing of a catalyst ink, and selective electroless plating of Au, Cu or Ni-B alloy on the catalyst template to form desired patterns with a minimal line width of about 200 um. The adherence of the metal layer deposited on glass is significantly enhanced due to the surface modification of self-assembled aminosilane layer. The non-photolithographic approach could be cost-effective for prototype and small patch of production of metallic patterns, simple electric circuits and other electronic device parts.
