Abstract: A method and structure for a piezoelectric ink jet printhead. The method can include forming a piezoelectric composite from a liquid sol-gel solution. A first layer of the liquid sol-gel solution can be deposited onto a substrate using, for example, a spin coat process, wherein the substrate may be a printhead diaphragm. The first layer may be partially cured, then a second layer of the liquid sol-gel solution can be deposited onto the partially cured first layer, which is then partially cured. Any number of layers of liquid sol-gel solution can be deposited to result in a piezoelectric composite having a suitable thickness. Subsequently, all of the partially cured layers are fully cured. Printhead processing can continue to form a completed piezoelectric ink jet printhead.

Abstract translation: 压电喷墨打印头的方法和结构。 该方法可以包括从液体溶胶 - 凝胶溶液形成压电复合材料。 可以使用例如旋涂工艺将液体溶胶 - 凝胶溶液的第一层沉积到基底上，其中基底可以是打印头隔膜。 第一层可以部分固化，然后可以将第二层液体溶胶 - 凝胶溶液沉积到部分固化的第一层上，然后将其部分固化。 可以沉积任何数量的液体溶胶 - 凝胶溶液，以产生具有合适厚度的压电复合材料。 随后，所有部分固化的层完全固化。 打印头处理可以继续形成完成的压电喷墨打印头。
