Abstract

See full text

Methods of manufacturing transducers with triangular cross-sectional shaped pillars are disclosed herein. According to one aspect of the present application, a plurality of first, second and third troughs are formed in a transducer substrate in first, second and third directions, respectively, to form an array of pillars. In one embodiment, the first direction is substantially parallel to a longitudinal axis of the substrate, the second direction is substantially perpendicular to the longitudinal axis of the substrate, and the third direction is oblique to the longitudinal axis of the substrate. The resulting array of pillars can be configured to suppress lateral modes of a high frequency ultrasound transducer.
