Abstract :
This paper describes selective area PZT-preparation based on PZT precursor etching for sol-gel method, and its application to the fabrication of PZT disk transducers of nearly 1 μm thickness without repeating any process. Using this method, we show that PZT disk transducers of 0.8 μm thickness can be fabricated only by a single process. The piezoelectricity of the transducers is discussed by an ultrasonic pulse echo method
