摘要:
The invention provides an information recording device, an information reproducing device, and an information recording medium capable of securely protecting copyright of main information, and preventing illegal access to the recorded main information. The information recording device (3) is provided with a medium unique information generating section (9) that generates second sub information by data-converting stamper unique information based on disc identification information that differs for each optical disc after transferring main information and first sub information from a stamper (1′) having the main information and the first sub information recorded therein onto an optical disc (1), and a medium unique information recording section (10) that records the second sub information in the optical disc (1) having recorded therein in advance the main information and the first sub information in a form different from the forms of the main information and the first sub information.
摘要:
A recording medium for storing a data stream is comprised of first error correcting codes obtained by encoding first information, second error correcting codes obtained by encoding second information, and synchronization signals. In the data stream, the second error correcting codes and the synchronization signals alternatively interleave the first error correcting codes. The second error correcting codes have the same number of corrections as the first error correcting codes. A code length of the second error correcting codes is shorter than a code length of the first error correcting codes.

摘要:
A method of inspecting defects of a plurality of patterns that are formed on a substrate to have naturally the same shape. According to this method, in order to detect very small defects of the patterns with high sensitivity without being affected by irregular brightness due to the thickness difference between the patterns formed on a semiconductor wafer, a first pattern being inspected is detected to produce a first image of the first pattern, the first image is stored, a second pattern being inspected is detected to produce a second image of said second pattern, the stored first image and the second image are matched in brightness, and the brightness-matched first and second images are compared with each other so that the patterns can be inspected.
摘要:
For the purpose of reducing a false report and shortening inspection time, an area to be inspected is locally inspected under optimum inspection conditions. In order to avoid the number of detected defects from increasing explosively, and thereby to facilitate control of a critical defect, general-purpose layout data, which is used for producing a mask of a semiconductor wafer, is accumulated in a design information server 2. With reference to the layout data, an area to be inspected, which is inspected by a pattern inspecting apparatus 1, is divided into partial inspection areas including a cell portion and a non-cell portion. Inspection parameters are set for each of the partial inspection areas. In addition, the defect reviewing apparatus 8 obtains an inspection result of the pattern inspecting apparatus 1. When obtaining a defect image, the defect reviewing apparatus 8 identifies a position, where the defect occurred, from among a cell portion, a non-cell portion, a pattern dense portion, and the like according to layout data. Moreover, the defect reviewing apparatus 8 sets inspection parameters, such as pickup magnification of this defect, in response to a result of the identification to set a control criterion of criticality.
摘要:
The distribution states of defects are analyzed on the basis of the coordinates of defects detected by an inspection apparatus to classify them into a distribution feature category, or any one of repetitive defect, congestion defect, linear distribution defect, ring/lump distribution defect and random defect. In the manufacturing process for semiconductor substrates, defect distribution states are analyzed on the basis of defect data detected by an inspection apparatus, thereby specifying the cause of defect in apparatus or process.

A recording medium for storing a data stream is comprised of first error correcting codes obtained by encoding first information, and second error correcting codes obtained by encoding second information, and synchronization signals. The first error correcting codes have a first correction capability. The second error correcting codes have a second correction capability higher than the first correction capability. In the data stream, the second error correcting codes and the synchronization signals alternatively interleave the first error correcting codes. The first and second error correcting codes are encoded using Reed-Solomon codes.
