Ultrasonic probe and manufacture thereof
专利汇可以提供Ultrasonic probe and manufacture thereof专利检索，专利查询，专利分析的服务。并且PURPOSE:To enable the transmitting and receiving of ultrasonic pulses at the highest efficiency by integrating a unit element electrode with lambda/4 plate to prevent the ringing of the ultrasonic pulse excited from a piezo-electric body. CONSTITUTION:Metal thin film electrodes 1 and 2 are provided entirely on one side of a high molecular piezo-electric film 3 by evaporation or the like while a resist material 10 is applied on the other side thereof corresponding to the size of clearance in a lambda/4 plate 2' concurrently serving as a strip-shaped electrode by screen printing or the like. Then, an exposing mask 11 is used to expose the material to light. In this case, the mask 11 is allowed to shield ultraviolet rays from the portion for the plate 2' to be set of the piezo-electric body 3, leaving a positive type photoresist on the clearance portion of the plate 2' only. A metal film 2' is set by plating using the metal thin film electrode of the piezo-electric body 3 thus obtained as plating electrode and after that, the material 10 and an access plate 2' and the like are removed. Then, the strip- shaped electrode and lambda/4 plate integrated type piezo-electric body 3 obtained via such a process is fastened on a support with an adhesive.，下面是Ultrasonic probe and manufacture thereof专利的具体信息内容。
