Abstract:
1. A device comprising: a film bulk acoustic resonator (FBAR); wherein the FBAR has at least one functionalized surface, wherein the functionalized surface is configured to react with target molecules, said FBAR being mounted on a substrate comprising a semiconductive layer and first and second, spaced apart insulating layers, said FBAR having a first edge contacting said first insulating layer and a second edge contacting said second insulating layer, wherein said semiconductive layer, said spaced apart insulating layers, and said FBAR define a void region therebetween; wherein the device is configured such that when the functionalized surface is exposed to the target molecules, the FBAR, the first and second insulating layers and the semiconductor layer except for the functionalized surface are not exposed to the target molecules.
