A technique for routing data for improved deduplication in a storage server cluster includes computing, for each node in the cluster, a value collectively representative of the data stored on the node, such as a “geometric center” of the node. New or modified data is routed to the node which has stored data identical or most similar to the new or modified data, as determined based on those values. Each node stores a plurality of chunks of data, where each chunk includes multiple deduplication segments. A content hash is computed for each deduplication segment in each node, and a similarity hash is computed for each chunk from the content hashes of all segments in the chunk. A geometric center of a node is computed from the similarity hashes of the chunks stored in the node.

A process to form a FET using a replacement gate. An example feature is that the PMOS sacrificial gate is made narrower than the NMOS sacrificial gate. The PMOS gate is implanted preferably with Ge to increase the amount of poly sacrificial gate that is oxidized to form PMOS spacers. The spacers are used as masks for the LDD Implant. The space between the PLLD regions is preferably larger that the space between the NLDD regions because of the wider PMOS spacers. The PLDD tends to diffuse readily more than NLDD due to the dopant being small and light (i.e. Boron). The wider spacer between the PMOS regions improves device performance by improving the short channel effects for PMOS. In addition, the oxidization of the sacrificial gates allows trimming of sacrificial gates thus extending the limitation of lithography. Another feature of an embodiment is that a portion of the initial pad oxide is removed, thus reducing the amount of undercut created during the channel oxide strip for the dummy gate process. This would improve on the gate overlap capacitance for a T-gate transistor. In a second embodiment, two metal gates with different work functions are formed.
