Abstract: An optical transceiver may include a circuit board, lasers, and a PLC including optical multiplexers and demultiplexers. The PLC may be coupled to fiber optic lines at a forward edge of the PLC, with a rear edge of the PLC receiving light for transmission generated by the lasers. Light received at the forward edge of the PLC may be demultiplexed into data channels and routed to a top surface of the PLC for optoelectronic conversion by photodetectors. In some embodiments each data channel is routed into a corresponding plurality of waveguides, with each of the corresponding plurality of waveguides providing light to the same photodetector. In some embodiments at least some receive side electronic circuitry, other than photodetectors, is stacked on top of the PLC.

Abstract: A wafer cleaning apparatus provides two opposed brushes for brushing a vertically disposed wafer in a tank which can contain a process liquid. A pressure controller adaptively controls the pressure exerted by the brushes on the wafer to compensate for brush wear. Rim driving wheels engage the wafer periphery with a porous jacket coupled to a fluid delivery system, thereby simultaneously rotating and cleaning the periphery of the wafer. The apparatus includes a fluid delivery system for separately and independently delivering a plurality of constituents of a cleaning solution to the brushes, thereby ensuring that a freshly mixed cleaning solution reaches the wafer. The tank can be filled with a process liquid through which megasonic waves provided by a transducer can propagate and impinge upon the wafer thereby enhancing the cleaning of the wafer or the brushes.
