Abstract
PURPOSE: To improve the yield of production by providing pyro-electric wafer with lead wire draw-out electrode extending over plural pyro-electric type infrared detecting elements and also by dividing the wafer into plural elements and the electrode into plural parts at the same time so that evaporation mask holes are enlarged in size and lessened in number.
CONSTITUTION: A pyro-electric wafer 1, which is composed of crystals of LiTaO3, is ground to a prescribed thickness, and an Ni-Cr back electrode 2, which is previous to infrared rays, is attached to thus ground surface. And then, this surface is placed on an insulated supporting table 3 which is provided with coating of Ag paste 4, and these are these are jointed together into a continuous body by being heated and cooled. And then, the surface of the wafer 1 is again ground to the final thickness, an Ni-Cr surface electrode 5 is attached to thus ground surface, and on thus attached surface electrode, plural Al lead wire drawout electrodes 9 are formed by means of soldering at equal intervals using mask provided with big holes. And then, the electrode 9 and the supporting table 3 are equally divided into 4 parts while dicing to obtain individual pellets containing divided electrodes 9', and then, respective lead wires 7 are connected to these electrode 9' by ultrasonic bonding.
