A method for fabricating an acoustic resonator comprises providing a substrate; fabricating a first electrode adjacent the substrate; fabricating a piezoelectric layer adjacent the first electrode; depositing electrode material to form a second electrode up to a first thickness adjacent the piezoelectric layer; depositing a first photo mask over the second electrode; depositing additional electrode material to form the second electrode up to a second thickness; removing the photo mask thereby forming a recessed region in the second electrode; and filling the recessed region with a fill material.

Method of fabricating an acoustic resonator comprising a filled recessed region

An acoustic resonator comprises: a substrate; a first electrode adjacent the substrate; a layer of piezoelectric material adjacent the first electrode; a second electrode adjacent the layer of piezoelectric material; and a passivation layer adjacent the layer of piezoelectric material. The passivation layer includes a recessed feature. Fill material is provided in the recessed feature of the passivation layer.

Acoustic resonator performance enhancement using selective metal etch

A single integrated wafer package includes a micro electromechanical system (MEMS) wafer, an active device wafer, and a seal ring. The MEMS wafer has a first surface and includes at least one MEMS component on its first surface. The active device wafer has a first surface and includes an active device circuit on its first surface. The seal ring is adjacent the first surface of the MEMS wafer such that a seal is formed about the MEMS component. An external contact is provided on the wafer package. The external contact is accessible externally to the wafer package and is electrically coupled to the active device circuit of the active device wafer.

A technique for producing a scent from a hand-held device involves receiving a scent mixture formula at a hand-held device, converting the scent mixture formula into dispense control signals, and generating a scent mixture in response to the dispense control signals, the scent mixture being generated from different base scents that are individually stored within the hand-held device. In an embodiment, the scent mixture formula includes a scent identifier and a scent quantifier related to each base scent that is used to generate the scent mixture. Mixing multiple base scents to generate scent mixtures greatly expands the range of different scents that can be generated at a hand-held device that stores a limited number of base scents. Further, encoding a scent mixture into a scent mixture formula enables scent mixtures to be easily shared between hand-held devices.

A dispense system stores a scented material or materials and is provided with an electrical interface that is compatible with a hand-held device. The dispense system can be connected to the hand-held device and driven with the help of the hand-held device to dispense the scented material. The dispense system can be configured to store different scented materials that can be mixed to create different scents. Logic within the hand-held device supports the mixing and dispensing of the scented materials.

The present invention provides an apparatus and method for viewing a depiction of an object (for example a solder joint) in a multi-dimensional manner, morphing the object's depiction using a graphical user interface to upper and lower acceptable tolerance limits and storing the tolerance limits for use in a test/inspection apparatus. The invention relates to the translation of human visual inspection-analysis of an object into physical quantifiable parameters used in an inspection device via a graphical user interface.
