    摘要: A prediction error generating unit generates a predictive vector from the motion vectors of a plurality of adjacent blocks, and obtains a difference from a target vector. A plurality of variable-length coding units respectively encode the output of the prediction error generating unit with different encoding methods. A determining unit estimates the accuracy of the predictive vector generated by the prediction error generating unit based on the degrees of non-uniformity of the motion vectors of the plurality of adjacent blocks. A selecting unit selects one of the encoding results obtained by the plurality of variable-length coding units.

    摘要: In a manufacturing method for performing plasma etching on a second surface of a semiconductor wafer that has a first surface where an insulating film is placed in dividing regions and the second surface which is opposite from the first surface and on which a mask for defining the dividing regions is placed thereby exposing the insulating film from etching bottom portions by removing portions that correspond to the dividing regions and subsequently continuously performing the plasma etching in the state in which the exposed surfaces of the insulating film are charged with electric charge due to ions in the plasma thereby removing corner portions put in contact with the insulating film in the device-formation-regions, isotropic etching is performed on the semiconductor wafer at any timing.

    摘要: In a semiconductor wafer including a plurality of imaginary-divided-regions which are partitioned by imaginary-dividing-lines that are respectively arranged in a grid-like arrangement on the semiconductor wafer and a circumferential line that is the outer periphery outline of the semiconductor wafer, a mask is placed so as to expose an entirety of surfaces of the wafer corresponding to respective removal-regions. The removal-regions are regions in approximately triangular form partitioned by the circumferential line of the wafer and the imaginary-dividing-lines. Then, plasma etching is performed on a mask placement-side surface of the wafer, by which the semiconductor wafer is divided into the individual semiconductor devices along dividing lines while portions corresponding to the removal-regions of the wafer are removed.
