Abstract:
An electronic device provided with a package housing a stacked structure formed by dies of semiconductor material, which have a respective integrated circuit and a respective top surface, which extends in a horizontal plane, and are stacked on one another in a vertical direction, transverse to the horizontal plane, and staggered parallel to the same horizontal plane. Provided at a first portion of the top surface is a first plurality of contact pads, and provided at a second portion of the top surface is a second plurality of contact pads. The first portion is covered by a overlying die, and the second portion is exposed and freely accessible. At least some of the contact pads of the first plurality are electrically coupled to internal through silicon vias traversing a substrate of the overlying die to put overlapping dies in electrical contact.
Abstract:
An electronic system supports superior coupling by implementing a communication mechanism that provides at least for horizontal communication for example, on the basis of wired and/or wireless communication channels, in the system. Hence, by enhancing vertical and horizontal communication capabilities in the electronic system, a reduced overall size may be achieved, while nevertheless reducing complexity in printed circuit boards coupled to the electronic system. In this manner, overall manufacturing costs and reliability of complex electronic systems may be enhanced.

Energy harvesting and scavenging circuitry is electrically coupled to the moveable electrode the electrode and is configured to provide electrical energy responsive to electrical energy generated by the moveable electrode, conductive fluid and the electrode through the reverse electrowetting phenomena due to movement of the moveable electrode relative to the electrode and to the conductive fluid on top of the electrode.
Abstract:
A pressure sensor with double measuring scale includes: a flexible body designed to undergo deflection as a function of a the pressure; piezoresistive transducers for detecting the deflection; a first focusing region designed to concentrate, during a first operating condition, a first value of the pressure in a first portion of the flexible body so as to generate a deflection of the first portion of the flexible body; and a second focusing region designed to concentrate, during a second operating condition, a second value of said pressure in a second portion of the flexible body so as to generate a deflection of the second portion of the flexible body. The piezoresistive transducers correlate the deflection of the first portion of the flexible body to the first pressure value and the deflection of the second portion of the flexible body to the second pressure value.

An electronic communications device includes a body of semiconductor material with an integrated electronic circuit, an inductive element, and a capacitive element. The capacitive element is formed by a first electrode and a second electrode positioned between the inductive element and the integrated electronic circuit. Tuning of the device circuitry is accomplished by energizing the inductive/capacitive elements, determining resonance frequency, and using a laser trimming operation to alter the structure of one or more of the first electrode, second electrode or inductive element and change the resonance frequency.

The resistance compensation circuit may be configured to measure an initial resistance of the first resistive region, and generate a voltage at the tuning element to tune an operating resistance of the first resistive region based upon the measured initial resistance.

An embodiment of a process for manufacturing a system for electrical testing of a through via extending in a vertical direction through a substrate of semiconductor material envisages integrating an electrical testing circuit in the body to enable detection of at least one electrical parameter of the through via through a microelectronic buried structure defining an electrical path between electrical-connection elements towards the outside and a buried end of the through via; the integration step envisages providing a trench and forming a doped buried region at the bottom of the trench, having a doping opposite to that of the substrate so as to form a semiconductor junction, defining the electrical path when it is forward biased; in particular, the semiconductor junction has a junction area smaller than the area of a surface of the conductive region in a horizontal plane transverse to the vertical direction, in such a way as to have a reduced reverse saturation current.
