Abstract: A method of forming a semiconductor device includes forming a first conductive feature on a bottom surface of an opening through a dielectric layer. The forming the first conductive feature leaves seeds on sidewalls of the opening. A treatment process is performed on the seeds to form treated seeds. The treated seeds are removed with a cleaning process. The cleaning process may include a rinse with deionized water. A second conductive feature is formed to fill the opening.

Abstract: Some embodiments provide a process of tunning sidewall profiles of gate openings prior to filling a replacement gate electrode layer therein to improve etching rate uniformity and stability during a subsequent gate electrode etch back process. Particularly, the profile sacrificial gate electrode is adjusted to be more straight profile rather than a bowl type profile, which reduces the seam void created in the replacement gate electrode during the replacement gate process. In some embodiments, tuning the profile of gate opening further includes performing a pullback etching process of the sidewall spacers prior to depositing gate dielectric layer and work function metal layer to achieve a wider opening for metal gate filling in the replacement gate process.

Abstract: A balancing mechanism of a machine tool turret includes an accommodation housing and a balancing device. The accommodation housing includes a slide rail located at a side of the accommodation housing, a groove located at an opposing side thereof and connected with the machine tool, a driving screw located in the slide rail along a specific axis, a driving motor located top of the accommodation housing and connected with the driving screw, and a block base located in the slide rail and connected with one end of the driving screw. The balancing device is located aside to the accommodation housing with one end fixedly connected with a top side of the accommodation housing and another end extended along the specific axis perpendicular to an axis of a work piece. In a finite installation space, the balancing mechanism has the way in embedding the accommodation housing without increasing the extra volume.

Abstract: A tailstock includes a main body, a lathe center unit arranged in a hollow hole of the main body, a sliding base coupled with the main body and having a slider configured at a side thereof for pairing a slide rail, and a clamping unit configured in the sliding base. The clamping unit for increasing clamping force of the tailstock further includes a connection plate having at least one positioning hole to connect the main body, at least one hydraulic rod bridging the slider and the main body, a plurality of loading devices ring-set about the hydraulic rod, and a plurality of sleeves ring-set with the corresponding loading devices.

Abstract: A slim speaker includes a casing having an enlarged front opening and a rear end with a magnetic circuit mounted thereto; a voice coil located over a central area of the magnetic circuit; a diaphragm located between the enlarged front opening of the casing and the voice coil; and a damper located behind the diaphragm to space from the latter. The diaphragm has at least one V-shaped bent section provided at a middle portion for bearing on a corresponding position on the damper. With these arrangements, the diaphragm not only has an effectively reduced overall height to largely reduce the assembled volume of the slim speaker and allow the slim speaker to be easily mounted in the limited inner space of an electric product, but also stabilizes the vibration of the voice coil to enable good resonance of sound.

Abstract: A position and directionality adjustable multi-range surround-sound speaker cabinet includes an elongated three-dimensional main body and a mounting bracket unit. A plurality of speakers is mounted at predetermined positions on front, rear, bottom, and two lateral sides of the main body. The mounting bracket unit includes a left and a right mounting bracket connected near to left and right ends of the bottom side of the main body, such that the main body is movably supported on and connected to the mounting bracket unit and can be adjusted to different elevation angles for changing sound wave transmission and directionality. And, the sound wave transmission can be changed or adjusted according to room size to obtain the most suitable surrounding sound effect.

Abstract: Aspects of the present invention provide a method and system for wakeup packet detection at gigabit speeds. A method for wakeup packet detection for high speed networking may include storing at least one data pattern in memory and matching at least a portion of an incoming frame to at least a portion of the at least one data pattern stored in memory upon instantaneous receipt the incoming frame. Accordingly, the matching occurs without buffering or storing at least a portion of the incoming frames in a buffer or memory. At least one power management event may be generated if the matching results in at least a portion of the incoming frame matching at least a portion of the at least one data pattern stored in memory.

Abstract: An improved speaker structure includes dual suspension edges connecting a support seat, a sound ring and a diaphragm. Therefore, when the speaker outputs, the dual suspension edge will not deviate and can perform a highly vertical cutting movement. Besides, the dual suspension edge can perform a flip-flop movement and distribution, and can compensate insufficient tensile force during reverse vibration so as to increase power, reduce distortion, and enable the diaphragm to be independently secured to a top portion of the sound ring to obtain better sound quality.

Abstract: A speaker structure having a supporting base with a magnetic circuit in a lower portion, a sound cylinder with a tube with wires on one end, which one end is placed in the magnetic circuit and the other end is higher than the supporting base. A vibration diaphragm having a round concave shape covers the top of the sound cylinder. A flexible free end fixture with a wave transmission in the middle section has one end connected to the supporting base and the other end directly connected to the tube of the sound cylinder. Thus favorable movement flexibility is achieved by the adhesion of the free end fixture at the lateral side of the sound cylinder. The space above the sound cylinder is vacant to independently install a vibration diaphragm with an enlarged area to effectively enhance the output of sound pressure.
