Title: Screen printable conductive paste compsn. - using a sealing glass compsn. as the permanent binder
IPC: H01L21/60
Filed: 1976-04-21
Abstract: Screen printable conductive paste deposited as thick layers on a semi-conductive substrate such as Si, and forms part of the active material, such as a finely divided metal or mixt. of metals to make the paste conductive. Specif. the paste contains a frit comprising 40-65% ZnO, 15-50% B2O3, 0-30% SiO2, 3-20% B2O5, 1-10% Li2O+CaO, and 0-10% Al2O3. The paste is screen printed through a masking pattern onto a pref. semiconductor substrate, which is dried at 100 degrees then fired at 500-800 degrees C. Used for mfr. of solar cells and thick film circuits. The contacts produced by screen printing according to the process form conductors of contact resistance of the order of 10-2 OMEGA-cm and area resistances of the order of 5 m OMEGA per square. The process is cheaper and quicker than vacuum deposition of contact material.
