Abstract: Techniques and mechanisms to provide mechanical support for a micromachined piezoelectric transducer array. In an embodiment, a transducer array includes transducer elements each comprising a respective membrane portion and a respective supporting structure disposed on or around a periphery of that membrane portion. The transducer elements are initially formed on a sacrificial wafer, wherein supporting structures of the transducer elements facilitate subsequent removal of the sacrificial wafer and/or subsequent handling of the transducer elements. In another embodiment, a polymer layer is disposed on the transducer elements to provide for flexible support during such subsequent handling.

Abstract: Optical components may be precisely positioned in three dimensions with respect to one another. A bonder which has the ability to precisely position the components in two dimensions can be utilized. The components may be equipped with contacts at different heights so that as the components come together in a third dimension, their relative positions can be sensed. This information may be fed back to the bonder to control the precise alignment in the third dimension.
