Abstract

This disclosure provides systems, methods, and apparatus for through substrate via inductors. In one aspect, a cavity is defined in a glass substrate. At least two metal bars are in the cavity. A first end of each metal bar is proximate a first surface of the substrate, and a second end of each metal bar is proximate a second surface of the substrate. A metal trace connects a first metal bar and a second metal bar. In some instances, one or more dielectric layers can be disposed on surfaces of the substrate. In some instances, the metal bars and the metal trace define an inductor. The inductor can have a degree of flexibility corresponding to a variable inductance. Metal turns can be arranged in a solenoidal or toroidal configuration. The toroidal inductor can have tapered traces and / or thermal ground planes. Transformers and resonator circuitry can be realized.

Description

[0001] priority information [0002] This application is claimed in co-pending Application No. 1, entitled THROUGH SUBSTRATE VIA INDUCTORS, filed Oct. 16, 2012, by Shenoy et al. (Attorney Docket No. QUALP155A / 121830U1) Priority to US Patent Application Serial No. 13 / 653,132, which is hereby incorporated by reference in its entirety for all purposes. technical field [0003] The present invention relates generally to inductors, and more particularly to through substrate via inductors. Background technique [0004] Electromechanical systems (EMS) include devices with electrical and mechanical elements, such as transducers such as sensors and actuators, optical components such as mirrors and optical films, and electronics. EMS devices or elements can be fabricated on a variety of scales, including but not limited to microscale and nanoscale. For example, microelectromechanical systems (MEMS) devices may include structures ranging in size from about one micron to hundreds of ...
