Burnthrough formulations

摘要

For solar cell fabrication, the addition of precursors to printable media to assist etching through silicon nitride or silicon oxide layer thus affording contact with the substance underneath the nitride or oxide layer. The etching mechanism may be by molten ceramics formed in situ, fluoride-based etching, as well as a combination of the two.

主权项

1. An ink comprising metal particles, a solvent, a dispersant, and a low melting point ceramic precursor, wherein the low melting point ceramic precursor reacts with other oxygen containing materials to form oxides and hydroxides.
