摘要
红外热释电探测器的关键是敏感元的研制,而敏感元主要是由具有一定图形的铁电薄膜和上下电极构成。采用半导体光刻工艺,利用化学腐蚀法成功地对PZT铁电薄膜进行了刻蚀,同时采用剥离技术对相应的电极实现了图形化。
A critical component in the pyroelectric IR sensor is the sensing organ, which consists of the ferroelectric thin film in certain shape and its upper and bottem electrodes. In the paper, the ferro -electric thin films are micropatterned successfully by optical lithography and chemical etching. The electrodes are finally formed by lift - off techniques.
