摘要: Provided herein is a method of making an integrated circuit device using copper metallization on 1-3 PZT composite. The includes providing overlay electroplated immersion gold (Au) to cover metal traces, the preventing oxidation 1 :3 composite with material. Also included formation Au nickel electrodes achieve pad for external connections.
