光刻技术在PVDF压电薄膜电极制作中的应用
摘要
为了在聚偏二氟乙烯(PVDF)压电薄膜上得到特定形状和尺寸的金电极
利用光刻技术的基本原理
分别实施了2种制备方案
即正性胶保护法和负性胶保护法。实验结果表明:负性胶保护法不能用于PVDF压电薄膜金电极的制作
而正性胶保护法能够成功地完成PVDF压电薄膜上金电极的制作
并已经成功地应用于高频超声换能器研制中。
Abstract
Based on the principle of phototeching technology
two different projects
namely positive resist protection and negative resist protection
are performed to realize the preparation of the golden electrodes with special shape and dimension on the PVDF piezoelectric film.The experimental results indicate that we can obtain the ideal golden electrodes only in the project of positive resist protection
not in the project of negative resist protection.The PVDF piezoelectric film with the golden electrodes can used in the manufacture of high-frequency ultrasonic sensor.
