Abstract: In various embodiments, the present disclosure provides semiconductor devices, packages, and methods. In one embodiment, a device includes a die pad, a lead that is spaced apart from the die pad, and an encapsulant on the die pad and the lead. A plurality of cavities extends into at least one of the die pad or the lead to a depth from a surface of the at least one of the die pad or the lead. The depth is within a range from 0.5 μm to 5 μm. The encapsulant extends into the plurality of cavities. The cavities facilitate improved adhesion between the die pad or lead and the encapsulant, as the cavities increase a surface area of contact with the encapsulant, and further increase a mechanical interlock with the encapsulant, as the cavities may have a rounded or semi-spherical shape.

Abstract: In an embodiment, a device comprises a memory, which, in operation, stores data samples associated with a plurality of data sensors, and circuitry, coupled to the memory, wherein the circuitry, in operation, generates synchronized output data sets associated with the plurality of data sensors. Generating a synchronized output data set includes: determining a reference sample associated with a sensor of the plurality of sensors; verifying a timing validity of a data sample associated with another sensor of the plurality of sensors; identifying a closest-in-time data sample associated with the another sensor of the plurality of sensors with respect to the reference sample; and generating the synchronized output data set based on interpolation.

Abstract: Transistors having partially recessed gates are constructed on silicon-on-insulator (SOI) semiconductor wafers provided with a buried oxide layer (BOX), for example, FD-SOI and UTBB devices. An epitaxially grown channel region relaxes constraints on the design of doped source and drain profiles. Formation of a partially recessed gate and raised epitaxial source and drain regions allow further improvements in transistor performance and reduction of short channel effects such as drain induced barrier lowering (DIBL) and control of a characteristic subthreshold slope. Gate recess can be varied to place the channel at different depths relative to the dopant profile, assisted by advanced process control. The partially recessed gate has an associated high-k gate dielectric that is initially formed in contact with three sides of the gate. Subsequent removal of the high-k sidewalls and substitution of a lower-k silicon nitride encapsulant lowers capacitance between the gate and the source and drain regions.

Abstract: A microelectromechanical device is provided. A vibrating structure gyroscope included in the device employs a temporal differential sensing method alone or a spatial differential sensing method in combination with the temporal differential sensing method. When used in combination, the temporal sensing method may be applied before the spatial sensing method or applied after the spatial sensing method. The temporal differential sensing samples signals at times t1 and t2 when velocity of a sensing mass within the vibrating structure gyroscope is maximum and has an opposite sign. The temporal sensing method improves Euler and Centrifugal forces cancellation and increases the signal to noise ratio if forces remain equal at times t1 and t2. Applying a high sampling speed can result in times t1 and t2 being sufficiently close to each other and therefore cancel any error terms associated with Euler and Centrifugal forces.
