Yet, its use in MEMS has been constrained by limitations in processing PZT with current MEMS fabrication technology. The direct printing of PZT, in place of traditional manufacturing process such as spin-coating, enables on-demand deposition, allowing flexibility in thickness and shape of PZT deposition with a lower material cost. This thesis reports the thermal process optimization of the direct printing method to ensure the quality of PZT products. The pyrolysis portion of the thermal processing condition has been analyzed to show that pyrolysis performed at 360°C for 2 hours removes a sufficient amount of organic additives. There also exists a positive correlation for the duration of pyrolysis and the amount of desired perovskite phase crystal structure formed. The multi-layer printing has been experimented to remove the PZT voids in the sample. However, P-V curve or resistivity data were unable to show much improved performance. This is believed to be caused from the degradation of PZT, which were left under humid condition before the final annealing process. Further investigation will be continued to confirm the effect of multi-layer printing.","abstract_html":"Lead zirconate titanate (PZT) has been known for its strong piezoelectric property for micro-sensors and actuators.
