Abstract: A semiconductor package includes a base comprising a top surface and a bottom surface that is opposite to the top surface; a first semiconductor chip mounted on the top surface of the base in a flip-chip manner; a second semiconductor chip stacked on the first semiconductor chip and electrically coupled to the base by wire bonding; an in-package heat dissipating element comprising a dummy silicon die adhered onto the second semiconductor chip by using a high-thermal conductive die attach film; and a molding compound encapsulating the first semiconductor die, the second semiconductor die, and the in-package heat dissipating element.

Abstract: An electronic device includes a pair of depletion gates, an accumulation gate, and a conductive resonator. The depletion gates are spaced apart from each other. The accumulation gate is over the depletion gates. The conductive resonator is over the depletion gates and the accumulation gate. The conductive resonator includes a first portion, a second portion, and a third portion. The first portion and the second portion are on opposite sides of the accumulation gate. The third portion interconnects the first and second portions of the conductive resonator and across the depletion gates. A bottom surface of the first portion of the conductive resonator is lower than a bottom surface of the accumulation gate.

Abstract: A device comprises a first transistor, a second transistor, a first contact, and a second contact. The first transistor comprises a first gate structure, first source/drain regions on opposite sides of the first gate structure, and first gate spacers spacing the first gate structure apart from the first source/drain regions. The second transistor comprises a second gate structure, second source/drain regions on opposite sides of the second gate structure, and second gate spacers spacing the second gate structure apart from the second source/drain regions. The first contact forms a first contact interface with one of the first source/drain regions. The second contact forms a second contact interface with one of the second source/drain regions. An area ratio of the first contact interface to top surface the first source/drain region is greater than an area ratio of the second contact interface to top surface of the second source/drain region.

Abstract: An electrical device and an operation control method are provided. The electronic device includes a touch module and a processor. The touch module includes a touchable region. The touchable region is divided into at least a first touchable region and a second touchable region. The first touchable region is configured to implement a first function. The second touchable region is configured to implement the first function and a second function. The processor is electrically connected to the touch module. When at least one first touch point is detected in the first touchable region, at least one second touch point is detected in the second touchable region, and the processor determines that a distance between the first touch point and the second touch point is within a predetermined distance, the second touchable region is switched to implementing the first function.

Abstract: The invention is related to a light control film. The light control film includes a transparent substrate having a light incident surface and a light emitting surface, and a plurality of microcavity structures formed on the light incident surface of the transparent substrate. The microcavity structures are in inverted-pyramid shape and each microcavity structure is formed by at least four faces.

Abstract: A reverse gear device of a combined variable transmission system includes a housing which is mounted on the rear wheel axle of a motor scooter for housing a drive bevel gear, a driven bevel gear, an idle bevel gear, an idle gear shaft, shifting forks, and a sector plate cam. The drive bevel gear and the driven bevel gear are identical in specification to each other and are mounted at two sides of the rear wheel axle on the basis of a toothed cone center. The drive bevel gear and the driven bevel gear are provided with a groove facing the toothed cone center. The drive bevel gear is disposed with the axle by a spline hole. The driven bevel gear is disposed with the axle by a round hole for the power transmission in the forward motion.

Abstract: A differential gear comprises power input sprocket gear, differential pinion shaft, differential pinion, differential pinion support seat, side support cover, and differential side gear. Two differential pinions and two differential pinion support seats are mounted on the differential pinion shaft. Two differential side gears are engaged at right angle with the differential pinions. When two differential side gears turn synchronously, the differential pinions turn around the power input sprocket gear. When one of two differential side gears is prevented from turning, the differential pinions turn independently of each other to permit a difference in speeds of the differential side gears, thereby enabling the power input sprocket gear to engage in normal power transmission.
