Manufacturing method to prevent tof (time of flight) fail in probe acquisition inspection

Abstract

A transducer element for an ultrasound probed that is disposed on a base block includes a first portion having a first curvature and a second portion having a second curvature with a radius shorter than the first curvature. The transducer element includes an FPC disposed across the first portion and the second portion and a laminate including a transducer disposed on the FPC. The laminate including the transducer includes a layer of a piezoelectric element, wherein the laminate including the transducer includes a relatively shallow groove that does not completely cut the layer of the piezoelectric element and a relatively deep groove that completely cuts the layer of the piezoelectric element, the relatively shallow groove and the relatively deep groove are alternately disposed at a position corresponding to the first portion, and a plurality of the relatively deep grooves are contiguously disposed at a position corresponding to the second portion.
