Abstract: A semiconductor detector of gravitational waves of a first frequency may include an oscillator having a metal coated oscillating member over a metal coated semiconductor substrate to be subjected to a Casimir attraction force towards the semiconductor substrate. The oscillator may be configured to exert a force to counterbalance the Casimir attraction force causing the oscillating member oscillates with a main harmonic resonance frequency equal to the first frequency. A displacement sensor may be coupled to the substrate and oscillating member and configured to sense oscillations and to generate corresponding sense signals. A pass-band filter may be tuned to the main harmonic resonance frequency and configured to generate band-pass replica signals of the sense signals, and an airtight package may be configured to keep a vacuum between the oscillating member and the semiconductor substrate. An array of semiconductor detectors and a method of detecting gravitational waves are also disclosed.

Abstract: An electronic device includes: a control terminal, which extends on a first face of a substrate; a first conduction terminal, which extends in the substrate at the first face of the substrate; a first insulating layer interposed between the control terminal and the first conduction terminal; a conductive path, which can be biased at a biasing voltage; and a protection element, coupled to the control terminal and to the conductive path, which forms an electrical connection between the control terminal and the conductive path and is designed to melt, and thus interrupt electrical connection, in the presence of a leakage current higher than a critical threshold between the control terminal and the first conduction terminal through the first insulating layer.

Abstract: A MEMS sensor has at least a movable element designed to oscillate at an oscillation frequency, and an integrated measuring system coupled to the movable element to provide a measure of the oscillation frequency. The measuring system has a light source to emit a light beam towards the movable element and a light detector to receive the light beam reflected back from the movable element, including a semiconductor photodiode array. In particular, the light detector is an integrated photomultiplier having an array of single photon avalanche diodes.
