ACTUATOR MANUFACTURING METHOD, SWITCHING APPARATUS, TRANSMISSION LINE SWITCHING APPARATUS, AND TEST APPARATUS |
摘要 |
To manufacture a switching apparatus that includes a piezoelectric actuator with increased lifespan, provided is a method for manufacturing a bimorph actuator, comprising first piezoelectric element layer formation of forming a first piezoelectric element layer on a substrate; support layer formation of forming a support layer made of an insulator on the first piezoelectric element layer; second piezoelectric element layer formation of forming a second piezoelectric element layer on the support layer; and removal of removing a portion of the substrate to form an actuator that includes the first piezoelectric element layer, the support layer, and the second piezoelectric element layer.
