METHOD AND DEVICE FOR FORMING CONDUCTIVE PATTERN, ULTRASONIC TRANSDUCER, AND ULTRASONIC IMAGE PICKUP DEVICE

摘要

PROBLEM TO BE SOLVED: To easily eliminate unnecessary conductive material after depositing the conductive material over the entire surface by preliminarily depositing a material for blocking the deposition of the conductive material to an object as a pattern corresponding to a negative print of a conductive pattern and depositing the conductive material to the object deposited with. SOLUTION: A screen printer prints a deposition inhibitor 206 such as oils and fats and metallic oxide paste as a pattern corresponding to a negative print of an electrode pattern. A sputtering device sputters conductive material such as gold and silver on th surface of a 1-3 composite piezoelectric material 200 subjected to screen printing. The conductive material is deposited onto the end face in the part where the edge faces of piezoelectric material 202 are exposed, and it is accumulated on the part that is covered with the inhibitor 206 and is not deposited to it directly. The inhibitor 206 printed on the surface of the material 200 is removed by an ultrasonic cleaning device.
