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.

Abstract: A plurality of transducer elements are formed. For each of the plurality of transducer elements, an electrode of the transducer element is formed on a first side of a support layer. A piezoelectric element of the transducer element is formed on the first side of the support layer. An interconnect of the transducer element is formed in the support layer. The support layer is thinned to expose a second side of the support layer. The interconnects of the plurality of transducer elements extend between the first side and the second side of the support layer. The second side of the support layer is bonded to a flexible layer with an adhesive material. Conductive fillers are disposed in the adhesive material. The interconnects of the plurality of transducer elements are each electrically coupled via the conductive fillers to the corresponding interconnect extending through the flexible layer.

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.
