Abstract: Improved methods and apparatus for stripping photoresist and removing ion implant related residues from a work piece surface are provided. According to various embodiments, the workpiece is exposed to a passivation plasma, allowed to cool for a period of time, and then exposed to an oxygen-based or hydrogen-based plasma to remove the photoresist and ion implant related residues. Aspects of the invention include reducing silicon loss, leaving little or no residue while maintaining an acceptable strip rate. In certain embodiments, methods and apparatus remove photoresist material after high-dose ion implantation processes.

Abstract: A multi-processor architecture for a network device that includes a plurality of barrel cards, each including: a plurality of processors, a PCIe switch coupled to each of the plurality of processors, and packet processing logic coupled to the PCIe switch. The PCIe switch on each barrel card provides high speed flexible data paths for the transmission of incoming/outgoing packets to/from the processors on the barrel card. An external PCIe switch is commonly coupled to the PCIe switches on the barrel cards, as well as to a management processor, thereby providing high speed connections between processors on separate barrel cards, and between the management processor and the processors on the barrel cards.
