Patent number: 11695384Abstract: A micro-electrical-mechanical system (MEMS) resonator device includes at least one functionalization material arranged over at least a central portion, but less than an entirety, of a top side electrode. For an active region exhibiting greatest sensitivity at a center point and reduced sensitivity along its periphery, omitting functionalization material over at least one peripheral portion of a resonator active region prevents analyte binding in regions of lowest sensitivity. The at least one functionalization material extends a maximum length in a range of from about 20% to about 95% of an active area length and extends a maximum width in a range of from about 50% to 100% of an active area width. Methods for fabricating MEMS resonator devices are also provided.Type: GrantFiled: August 10, 2022Date of Patent: July 4, 2023Assignee: Qorvo Biotechnologies, LLCInventors: Matthew Ryder, Rio Rivas, Thayne Edwards

Patent number: 11369960Abstract: Methods of fabricating a bulk acoustic wave resonator structure for a fluidic device. The methods can include a first step of disposing a first conductive material over a portion of a first surface of a substrate to form at least a portion of a first electrode, the substrate having a second surface opposite the first surface.

Patent number: 10866216Abstract: Operational configuration and temperature compensation methods are provided for bulk acoustic wave (BAW) resonator devices suitable for operating with liquids. Temperature compensation methods dispense with a need for temperature sensing, instead utilizing a relationship between (i) change in frequency of a BAW resonator at a phase with adequate sensitivity and (ii) change in frequency of a phase that is correlated to temperature. Operational configuration methods include determination of an initial phase response of a BAW resonator in which temperature coefficient of frequency is zero, followed by comparison of sensitivity to a level of detection threshold for a phenomenon of interest.Type: GrantFiled: December 15, 2016Date of Patent: December 15, 2020Assignee: Qorvo Biotechnologies, LLCInventors: Rick Morton, Kevin McCarron
