    • PURPOSE: To provide a method of manufacturing a piezoelectric thin film resonance device that can provide an air gap excellently under its lower electrode and to provide the piezoelectric thin film resonance device manufactured by the method. CONSTITUTION: The method of manufacturing the piezoelectric thin film resonance device includes the steps of: providing a support film 12 on the top of a substrate 11; forming a multilayer resonator 16 comprising a 1st electrode film 13 in contact with the support film 12, a 2nd electrode film 15 and a piezoelectric film 14 interposed between them on top of the support film 12; providing a resist film 17 for covering the layered resonator 16 and the support film 12; providing a hole 18 so as to expose part of the surface of the support film 12 to the resist film 17; introducing etching liquid from the hole 18, removing part of the lower region of the multilayer resonator 16 in the support film 12 and providing an air gap 19 to the removed part; and removing the resist film 17.
    • 目的:提供一种压电薄膜共振装置的制造方法,其可以在其下电极下方提供气隙,并提供通过该方法制造的压电薄膜共振装置。 构成:制造压电薄膜共振装置的方法包括以下步骤:在基板11的顶部设置支撑膜12; 形成包括与支撑膜12接触的第一电极膜13,第二电极膜15和介于其之间的压电膜14的多层谐振器16; 提供用于覆盖层状谐振器16和支撑膜12的抗蚀剂膜17; 设置孔18,以将支撑膜12的表面的一部分暴露于抗蚀膜17; 从孔18中引入蚀刻液,去除支撑膜12中的多层谐振器16的下部区域的一部分,并向移除的部分提供气隙19; 并除去抗蚀膜17。
