Publication number: 20130300259Abstract: A bulk acoustic wave resonator structure that isolates the core resonator from both environmental effects and aging effects. The structure has a piezoelectric layer at least partially disposed between two electrodes. The structure is protected against contamination, package leaks, and changes to the piezoelectric material due to external effects while still providing inertial resistance. The structure has one or more protective elements that limit aging effects to at or below a specified threshold. The resonator behavior is stabilized across the entire bandwidth of the resonance, not just at the series resonance. Examples of protective elements include a collar of material around the core resonator so that perimeter and edge-related environmental and aging phenomena are kept away from the core resonator, a Bragg reflector formed above or below the piezoelectric layer and a cap formed over the piezoelectric layer.Type: ApplicationFiled: July 15, 2013Publication date: November 14, 2013Applicant: CYMATICS LABORATORIES CORP.Inventors: Rajarishi Sinha, L.

Publication number: 20070241433Abstract: A semiconductor device package comprises a container including a base and sidewalls. The base is configured to support a semiconductor device chip, and a lead frame extends through at least one of the sidewalls. A portion of the lead frame within the sidewall has at least one aperture penetrating into the lead frame. The sidewall material extends into the aperture, thereby forming a strong interfacial bond that provides a low leakage, sidewall-lead-frame interface. The base has a reentrant feature that is positioned within the thickness of at least one of the sidewalls and engages the at least one sidewall, thereby forming a low leakage base-sidewall interface. The top surface of the base has a groove that is positioned within the thickness of at least one of the sidewalls and engages the at least one sidewall, thereby enhancing the low leakage base-sidewall interface.Type: ApplicationFiled: April 19, 2007Publication date: October 18, 2007Inventors: Patrick Carberry, Jeffery Gilbert, George Libricz, Ralph Moyer, John Osenbach, Hugo Safar, Thomas Shilling
