Claim Text:
1. An ultrasound transducer assembly comprising at least one row of ultrasound transducer elements for transmitting ultrasound waves in a general transmission direction comprising: a semiconductor chip; and the ultrasound transducer elements of the row each comprising: a piezoelectric layer having a top surface, a bottom surface and a side surface with respect to the general transmission direction; a bottom electrode layer located on the bottom surface which is electrically coupled to the semiconductor chip; and a top electrode layer located on the top surface and facing the general transmission direction; a conductive connection layer electrically coupling the top electrode layers of the elements of the row, wherein a conductive layer is applied on the side surface of the piezoelectric layer of at least one of the elements of the row, such that the conductive layer electrically couples the top electrode layer and the bottom electrode layer of the element, wherein the bottom electrode layer of the at least one of the elements electrically couples the conductive connection layer to the semiconductor chip.
