Abstract
A method of manufacturing multiple dimension transducer arrays of multiple layer elements from modules is provided. A plurality of multiple layer strips are formed. The strips are separate, such as an elongated strip corresponding in size to one row of elements. Connections between the electrodes of various layers or separate connections from the various electrodes to a bottom of the strip are formed on the separate multiple layer strips. The separate strips are then aligned within a frame and bonded together. The resulting sheet of multiple layer transducer material is then diced to form elements. Due to the previous interconnection of electrodes, each element includes electrical connections for each of the layer electrodes, avoiding the need for vias or high aspect ratio sputtering.
