Publication number: 20140303912Abstract: Inline yield monitoring may include the use of one or more modules of algorithmic software. Inline yield monitoring may include the use of two related algorithmic software modules such as a learning and a prediction module. The learning module may learn critical PET (parametric electrical test) parameters from data of probe electrical test yields and PET attribute values. The critical PET parameters may best separate outliers and inliers in the yield data. The prediction module may use the critical PET parameters found by the learning module to predict whether a wafer is an inlier or an outlier in a probe test classification.Type: ApplicationFiled: April 1, 2014Publication date: October 9, 2014Applicant: KLA-Tencor CorporationInventors: Saibal Banerjee, Sonu Maheshwary, John Charles Robinson, Dale Legband

Patent number: 8767734Abstract: A source-address independent, multi-path routing method for use in a communication network is disclosed. A network node uses an information packet's destination address to determine a plurality of neighbors it has a proportional likelihood to forward that packet to, such that packets can be sent over multiple paths to a destination node without undesirable looping. Multiple-neighbor proportional forwarding routing tables are determined by computing a directed graph of multiple optimal paths to each destination node. Optimal paths and forwarding proportions are based on link capacities. The multi-path routing method provides maximized throughput, reduced congestion and superior load balancing over single-path routing. Source-address independence also overcomes a major problem of more traditional source-address dependent multi-path routing methods. The source-address independent, multi-path routing method can be implemented in mixed networks where some nodes do not implement the method.Type: GrantFiled: October 5, 2009Date of Patent: July 1, 2014Assignee: BCK Networks, Inc.Inventors: Raghava Kondepudy, Saibal Banerjee, Gano Broto Chatterji

Patent number: 7822026Abstract: A transit device and system that include a first link configured to receive a plurality of packets, and a second link communicatively coupled to the first link via a slow protocol filter. The plurality of packets include a first type of packet (e.g., data packets) and a second type of packet (e.g., slow protocol control packets). The transit device also includes a slow protocol filter that couples the first link to the second link, with the slow protocol filter being coupled to a local slow protocol client (e.g., local host CPU). Moreover, the slow protocol filter is configured to receive the plurality of packets from the first link, and to determine whether each of the plurality of packets is of the first type or the second type. The slow protocol filter also is configured to transmit each of the plurality of packets that are of the first type to the second link, and to transmit each of the plurality of packets that are the second type to the local slow protocol client.Type: GrantFiled: December 15, 2005Date of Patent: October 26, 2010Assignee: Allied Telesis, Inc.Inventors: Saibal Banerjee, Alexander Tom

Patent number: 6999614Abstract: A method and system that optionally allows a user to view image defects organized by natural groupings based on features of the images. The natural groupings make it easier for the user to organize some or all of the images into classes in a training set of images. A feature vector is extracted from each image in the training set and stored, along with its user-specified class, for use by an automatic classifier software module. The automatic classifier uses the stored feature vectors and classes to automatically classify images not in the training set. If the automatically classified images do not match images manually classified by the user, the user modifies the training set until a better result is obtained from the automatic classifier. The system can provide feedback to an inspection system designed to aid in the setup and fine-tuning of the inspection system.Type: GrantFiled: November 28, 2000Date of Patent: February 14, 2006Assignee: KLA-Tencor CorporationInventors: David Bakker, Saibal Banerjee, Ian R.
