    Abstract: A probe card includes a number probes. Each probe is adapted to contact a corresponding terminal of a circuit integrated in at least one die of a semiconductor material wafer during a test phase of the wafer. The probes include at least one probe adapted to provide and/or receive a radio frequency test signal to/from the corresponding terminal during the test phase. The probe card further includes at least one electromagnetic shield structure corresponding to the at least one probe adapted to provide and/or receive the radio frequency test signal for the at least partial shielding of an electromagnetic field irradiated by such at least one probe adapted to provide and/or receive the radio frequency test signal.

    Abstract: An electronic device having a functional portion and a test portion. The test portion includes a boundary scan register formed by a plurality of test cells arranged in the body according to a register sequence, where first test cells are configured to form a serial-to-parallel converter and second test cells are configured to form a parallel-to-serial converter. The test cells are each coupled to a respective data access pin of the device and to a respective input/output point of the functional part and have a first test input and a test output. The boundary scan register defines two test half-paths formed, respectively, by the first test cells and by the second test cells. The first test cells are directly coupled according to a first sub-sequence, and the second test cells are directly coupled according to a second sub-sequence.

    Abstract: The integrated electronic device detects the pressure related to a force applied in a predetermined direction within a solid structure. The device includes an integrated element that is substantially orthogonal to the direction of application of the force. First and second conductive elements are configured to face an operating surface. A measure module includes first and second measurement terminals which are electrically connected to the first and second conductive elements, respectively. A detecting element is arranged in the predetermined direction such that the operating surface is sandwiched between the first and second conductive elements and this detecting element. An insulating layer galvanically insulates the first and second conductive elements. A layer of dielectric material is sandwiched between the detecting element and the insulating layer, and is elastically deformable following the application of the force to change an electromagnetic coupling between the detecting element and the first and second conductive elements.

    Abstract: A tensile stress measurement device is to be attached to an object to be measured. The tensile stress measurement device may include an IC having a semiconductor substrate and tensile stress detection circuitry, the semiconductor substrate having opposing first and second attachment areas. The tensile stress measurement device may include a first attachment plate coupled to the first attachment area and extending outwardly to be attached to the object to be measured, and a second attachment plate coupled to the second attachment area and extending outwardly to be attached to the object to be measured. The tensile stress detection circuitry may be configured to detect a tensile stress imparted on the first and second attachment plates when attached to the object to be measured.
