Abstract
A wide semiconductor transducer device comprises a linear array of semiconductor chips. Each of the semiconductor chips has a plurality of transducer elements arranged on it along a front edge at a constant spacing, the constant spacing being maintained across the semiconductor chip boundaries. Each of the semiconductor chips also includes associated transducer circuits which are each connected one of the plurality of transducer elements formed on the semiconductor chip. While the requirement that the transducer elements maintain the constant spacing requires them to be located within a damage zone created during the dicing and/or thermally induced compression of the semiconductor chip, the associated transducer circuits can be located within an interior portion of the semiconductor chip. The interior portion of the semiconductor chip is located a sufficient distance from the edges of the semiconductor chip such that it does not encroach on the damage zone.
