Abstract: A resonant half-bridge flyback power converter includes: a first transistor and a second transistor which form a half-bridge circuit; a transformer and a resonant capacitor connected in series and coupled to the half-bridge circuit; and a switching control circuit configured to generate a first driving signal and a second driving signal to control the first transistor and the second transistor respectively for switching the transformer to generate an output voltage. The first driving signal is configured to magnetize the transformer. The second driving signal includes at most one pulse between two consecutive pulses of the first driving signal. The switching control circuit generates a skipping cycle period when an output power is lower than a predetermined threshold. A resonant pulse of the second driving signal is skipped during the skipping cycle period. The skipping cycle period is increased in response to the decrease of the output power.

Abstract: Embodiments disclosed herein relate to using an implantation process and a melting anneal process performed on a nanosecond scale to achieve a high surface concentration (surface pile up) dopant profile and a retrograde dopant profile simultaneously. In an embodiment, a method includes forming a source/drain structure in an active area on a substrate, the source/drain structure including a first region comprising germanium, implanting a first dopant into the first region of the source/drain structure to form an amorphous region in at least the first region of the source/drain structure, implanting a second dopant into the amorphous region containing the first dopant, and heating the source/drain structure to liquidize and convert at least the amorphous region into a crystalline region, the crystalline region containing the first dopant and the second dopant.

Abstract: The present disclosure relates to an integrated chip. The integrated chip includes a substrate having one or more interior surfaces forming a recess within an upper surface of the substrate. Source/drain regions are disposed within the substrate on opposing sides of the recess. A first gate dielectric is arranged along the one or more interior surfaces forming the recess, and a second gate dielectric is arranged on the first gate dielectric and within the recess. A gate electrode is disposed on the second gate dielectric. The second gate dielectric includes one or more protrusions that extend outward from a recessed upper surface of the second gate dielectric and that are arranged along opposing sides of the second gate dielectric.

Abstract: A method includes forming a gate stack on a first portion of a semiconductor substrate, removing a second portion of the semiconductor substrate on a side of the gate stack to form a recess, growing a semiconductor region starting from the recess, implanting the semiconductor region with an impurity, and performing a melt anneal on the semiconductor region. At least a portion of the semiconductor region is molten during the melt anneal.

Abstract: An automatic assembling system and method for camera lens units are provided. The system includes a main workstation, a barrel-feeding station, a lens-feeding station, and a camera lens-removing station. The method includes (A) operating a plurality of barrel-clamping units of the main workstation cyclically and intermittently along a feeding direction; (B) moving a plurality of barrels from a barrel standby area of the barrel-feeding station onto the barrel-clamping units in sequence; (C) moving a plurality of lens units from a lens standby area assembly of the lens-feeding station into the barrels to form the camera lens units; and (D) moving the camera lens units from the barrel-clamping units into a camera lens-collecting area of the camera lens-removing station. The steps (B, C, D) are performed in cooperation with the intermittent operations of the barrel-clamping units.

Abstract: A device for cutting a sub-finished assembly (1) of plastic lens (10) includes a cutting member (2) and a holding member (3). The cutting member has a base (20), an upper plate (21), an upper cutter (23) mounted on the upper plate, a lower plate (22), a lower cutter (24) mounted on the lower plate, guiding posts (25) mounted on the base and guiding the movement of the upper and the lower plates, and a stopper (26). The upper plate moves toward the lens before the lower plate and until the upper cutter contacts the cutting point beside the lens. The stopper stops the upper plate from further moving after the upper cutter contacts the cutting point beside the lens. The lower cutter is moved by the lower plate to cut the lens from the sub-finished assembly of the lens. The holding member holds the lens during cutting.

Abstract: A tone detector includes at least one circuit (hereinafter “single phase reference matcher”) that not only performs a convolution of an input signal with a reference signal, but also compares the result of convolution with a threshold to determine if there is a match, and if so drives a signal active indicating that tone is present. If there is no match, another circuit (hereinafter “phase shifter”) delays the reference signal by a fraction (e.g. ⅛) of the measuring period, thereby to introduce a phase shift (e.g. &pgr;/8) between the input signal and the reference signal. The “single phase reference matcher” again performs the just-described operation, this time with a delayed reference signal, and repeats the operation as often as necessary (e.g. eight times) to cycle through the entire measuring period, thereby to ensure that tone (if present in the input signal) is detected irrespective of phase, during one of the operations.
