An insulating encapsulation of laser direct structuring (LDS) material is molded onto the substrate and the semiconductor die. The insulating encapsulation of LDS material has a front surface including a first portion and a second portion separated by gaps therebetween. Laser direct structuring processing is applied to the first portion of the front surface to structure in the encapsulation of LDS material electrically conductive formations including electrically conductive lines over the front surface and to the second portion of the front surface of the encapsulation of LDS material to form thereon a reinforcing warp-countering structure. The separation gaps are left exempt from laser direct structuring processing and the reinforcing warp-countering structure is electrically insulated from the electrically conductive lines by LDS material left exempt from laser direct structuring processing at the separation gaps.

  • Patent number: 11808723
    Abstract: The present disclosure is directed to a gas sensor device that includes a plurality of gas sensors. Each of the gas sensors includes a semiconductor metal oxide (SMO) film, a heater, and a temperature sensor. Each of the SMO films is designed to be sensitive to a different gas concentration range. As a result, the gas sensor device is able to obtain accurate readings for a wide range of gas concentration levels. In addition, the gas sensors are selectively activated and deactivated based on a current gas concentration detected by the gas sensor device. Thus, the gas sensor device is able to conserve power as gas sensors are on when appropriate instead of being continuously on.

  • Patent number: 11811906
    Abstract: Cryptographic circuitry, in operation, conditionally swaps a first operand and a second operand of a cryptographic operation based on a control value. The conditional swapping includes setting a first mask of a number of bits and a second mask of the number of bits based on the control value, the first mask and the second mask being complementary and having a same Hamming weight. A result of a bitwise XOR operation on the first operand and the second operand is stored as a temporary value. A combination of bitwise logical operations are performed to conditionally swap the first operand and the second operand.

  • Patent number: 11808573
    Abstract: The MEMS gyroscope has a mobile mass carried by a supporting structure to move in a driving direction and in a first sensing direction, perpendicular to each other. A driving structure governs movement of the mobile mass in the driving direction at a driving frequency. A movement sensing structure is coupled to the mobile mass and detects the movement of the mobile mass in the sensing direction. A quadrature-injection structure is coupled to the mobile mass and causes a first and a second movement of the mobile mass in the sensing direction in a first calibration half-period and, respectively, a second calibration half-period. The movement-sensing structure supplies a sensing signal having an amplitude switching between a first and a second value that depend upon the movement of the mobile mass as a result of an external angular velocity and of the first and second quadrature movements.
