METHOD FOR IMPROVING PATTERNED SILVER CONDUCTIVITY

摘要

A method is used to improve the conductivity of silver disposed on a substrate. This silver is generally in the form of silver metal particles. The silver is treated with an aqueous solution comprising a conductivity enhancing agent to provide treated silver metal particles that are increased in conductivity. The treated silver metal particles are then dried. These two essential steps of treating and drying are repeated in at least one additional treatment cycle, in sequence, using the same or different conductivity enhancing agent, thereby improving the conductivity of the silver metal particles from one treatment cycle to another. This method can be carried out using an apparatus having a series of stations for carrying out each step in each treatment cycle.
