Abstract:
1. An ultrasound transducer array comprising: a substrate layer having: a first cell group comprising an ultrasound transducer cell, and a second cell group comprising an ultrasound transducer cell, wherein the first cell group and the second cell group are arranged on the first surface of the substrate layer with the first recess separating the first cell group and the second cell group; and a first low fragility material contacting the first pair of sidewalls and occupying a part of the first recess, wherein a fragility of the first low fragility material is lower than a fragility of the substrate layer, wherein the second pair of sidewalls and a surface of the first low fragility material facing the second recess define a dividing groove extending from the second surface of the substrate layer, and wherein a minimum width of the first recess is greater than a maximum width of the dividing groove.
