    摘要： An ink jet print head includes PZT films formed on a first surface of a single-crystal silicon substrate, ink cavities formed in the regions of the single-crystal silicon substrate which correspond in position to the PZT films, and a nozzle plate formed on a second surface of the single-crystal silicon substrate, which is opposite to the first surface. Each ink cavity is formed using anisotropical wet and dry etching, and wherein a portion of each ink cavity close to the first surface of the single-crystal silicon substrate is anisotropically dry etched.
