  • Publication number: 20150381217
    Abstract: A remote radio head unit (RRU) system is disclosed. The present invention is based on the method of adaptive digital predistortion to linearize a power amplifier inside the RRU. The power amplifier characteristics such as variation of linearity and asymmetric distortion of the amplifier output signal are monitored by a wideband feedback path and controlled by the adaptation algorithm in a digital module. Therefore, embodiments of the present invention can compensate for the nonlinearities as well as memory effects of the power amplifier systems and also improve performance, in terms of power added efficiency, adjacent channel leakage ratio and peak-to-average power ratio. The present disclosure enables a power amplifier system to be field reconfigurable and support multi-modulation schemes (modulation agnostic), multi-carriers, multi-frequency bands and multi-channels.

  • Patent number: 8944739
    Abstract: A wafer handling system with apparatus for transporting wafers between semiconductor fabrication tools. In one embodiment, the apparatus is a loadport bridge mechanism including an enclosure having first and second mounting ends, a docking port at each end configured and dimensioned to interface with a loadport of a semiconductor tool, and at least one wafer transport robot operable to transport a wafer between the docking ports. The wafer transport robot hands off or receives a wafer to/from a tool robot at the loadports of a first and second tool. The bridge mechanism allows one or more wafers to be transferred between loadports of different tools on an individual basis without reliance on the FAB's automated material handling system (AMHS) for bulk wafer transport inside a wafer carrier such as a FOUP or others.

  • Patent number: 8593567
    Abstract: A web camera with position adjustment function has a clamping apparatus, an extending arm and a camera module. The clamping apparatus includes a base and a supporting bracket. The supporting bracket is connected pivotally to a rear edge of the base and has a chamber and an open front. The extending arm is disposed inside the chamber of the supporting bracket of the clamping apparatus and is pivotally and slidably connected to the supporting bracket of the clamping apparatus. The camera module is connected pivotally to a front end of the extending arm. The extending arm can be operated to protrude out of the open front of the supporting bracket and then to rotate relative to the clamping apparatus. Therefore, a horizontal position of the camera module is changeable and various camera angles can be achieved.

  • Publication number: 20130245978
    Abstract: A system and method of controlling a semiconductor wafer fabrication process. The method includes positioning a semiconductor wafer on a wafer support assembly in a wafer processing module. A signal is transmitted from a signal emitter positioned at a predetermined transmission angle relative to an axis normal to the wafer support assembly to check leveling of the wafer in the module, so that the signal is reflected from the wafer. The embodiment includes monitoring for the reflected signal at a predetermined reflectance angle relative to the axis normal to the wafer support assembly at a signal receiver. A warning indication is generated if the reflected signal is not received at the signal receiver.
