Title: Fabien Dumont: Innovator in Acoustic Technology
Introduction
Fabien Dumont is a notable inventor based in Longwood, FL (US). He has made significant contributions to the field of acoustic technology, holding 2 patents that showcase his innovative approach to engineering.
Latest Patents
One of his latest patents is for a WLP BAW device with through-WLP vias. This invention relates to a wafer-level packaged (WLP) bulk acoustic wave (BAW) device, which includes a BAW resonator, a WLP enclosure, and an interconnect. The BAW resonator features a piezoelectric layer with an opening, a bottom electrode lead underneath the opening, and an interface structure that extends over the opening and contacts the bottom electrode lead. The WLP enclosure consists of a cap and an outer wall that forms a cavity, along with a through-WLP via that is vertically aligned with the opening of the piezoelectric layer. A portion of the interface structure is exposed to the through-WLP via, and the interconnect is formed within this via, electrically connecting to the interface structure.
Another significant patent involves acoustic filtering circuitry. This circuitry includes an input node, an output node, a signal transmission path, a series acoustic resonator, and a shunt acoustic resonator. The series acoustic resonator is coupled between the input and output nodes, and it features a positive temperature coefficient of frequency (TCF) for its parallel resonance frequency. The shunt acoustic resonator, on the other hand, has a negative TCF for its series resonance frequency. This design helps to significantly reduce self-heating in the acoustic filtering circuitry, thereby enhancing its performance.
