    摘要: An apparatus includes a low density parity check decoder operable to iteratively generate messages between a plurality of check nodes and variable nodes, and to calculate a fractional quality metric for a data block as it is decoded in the low density parity check decoder based at least in part on perceived values of data in the variable nodes. The fractional unsatisfied check quality metric is a probabilistic determination of a number of unsatisfied parity checks in the low density parity check decoder.

    摘要: A probabilistic approach of symbol error estimation is disclosed. The probabilistic approach of symbol error estimation reflects the number of symbol errors more precisely than the number of unsatisfied checks. The more precise quality metric calculated in accordance with the present disclosure allows a codec system to achieve a better overall performance. In addition, many other features that previously depend on the number of unsatisfied checks as the sector quality metric may also benefit by adopting the more precise quality metric.

    摘要: A method for manufacturing semiconductor substrates. The method includes providing a semiconductor wafer, which has an upper surface, a backside surface, and an edge region around a periphery of the semiconductor wafer. In a preferred embodiment, the upper surface is often for the manufacture of the integrated circuit device elements themselves. The method includes subjecting the semiconductor wafer to one or more process steps to form one or more films of materials on the backside surface. The method mounts the semiconductor wafer to expose the backside surface. The method rotates the semiconductor wafer in a circular manner. In a specific embodiment, the method includes supplying an acid solution containing fluorine bearing species, a nitric acid species, a surfactant species, and an organic acid species, on at least the backside surface as the semiconductor wafer rotates. The method causes removal of one or more contaminants from the backside surface, while a portion of the center region of the backside surface remains exposed as the semiconductor wafer rotates in the circular manner.
