Abstract:
Methods and systems are provided for a single element ultrasound transducer. In one embodiment, a method for the transducer comprises laminating a comb structure and a conductive base package into an acoustic stack with a non-conductive glue, grinding the acoustic stack, and dicing the ground acoustic stack along a plane extending from the top surface of the second fin of the conductive base package to the bottom surface of the acoustic stack. The resulting transducer may have a flat front face with a non-conductive groove separating a ground pad formed by the conductive base package from a signal pad formed by a matching layer of the comb structure.
