    摘要: A glass substrate for an information recording medium is manufactured by polishing the surface of a raw material glass plate. The polishing of the raw material glass plate is divided into a step for performing a first polishing process to roughly polish the surface of the raw material glass plate to be smooth and a step for performing a second polishing process to finely polish the surface of the roughly polished raw material glass plate to be smoother. The first polishing process uses a polishing pad made of a synthetic resin foam and slides the polishing pad on the raw material glass plate surface while supplying a polishing agent to roughly polish the surface. A pad dressing process is performed on the polishing pad before being used in the first polishing process. The pad dressing process polishes the surface of the polishing pad by sliding the polishing pad on a pad dresser including abrasive grains.

    摘要: An information recording medium glass substrate manufactured by polishing the surface of a raw material glass plate. The polishing is divided into two steps, a step for performing a first polishing process to roughly polish the surface of the raw material glass plate to be smooth and a step for performing a second polishing process to finely polish the surface of the roughly polished raw material glass plate to be smoother. The second polishing process, using a polishing pad made of foam, is divided into two stages, pre-polishing with a polishing agent including abrasive grains of cerium oxide and post-polishing with a polishing agent including abrasive grains of silicon oxide. A rinsing process is performed between the pre-polishing and the post-polishing to rinse the raw material glass plate after the pre-polishing with a washing liquid to wash away the abrasive grains collected in the polishing pad in pre-polishing during the rinsing process.

    摘要: This invention relates to a method for real time monitoring and verifying optical proximity correction (OPC) models and methods in production. Prior to OPC is performed on the integrated circuit layout, a model describing the optical, physical and chemical processes involving lithography should be obtained accurately and precisely. In general, the model is calibrated using the measurements obtained by running wafers through the same lithography, patterning, and etch processes. In this invention, a novel real time method for verifying and monitoring the calibrated model on a production or monitor wafer is presented: optical proximity corrected (OPC-ed) test and verification structures are placed on scribe lines or cut lines of the production or monitor wafer, and with pre-determined schedule, the critical dimensions and images of these test and verification structures are monitored across wafer and across exposure field.

    摘要: Disclosed is a method of reproducing optical information by applying laser light to the medium while rotating a recording medium having concentric information tracks or a spiral information track so that the linear velocity of the medium is constant, and thereby reproducing the information recorded on the recording medium by the reflected light. In this method, in moving a reproduction radial position to a second radial position different from the current position, a laser power is changed to second laser power, which is different from current laser power, and then the light spot is moved to the second radial position. This method can prevent degradation of a medium in reproduction light resistance caused by substantially high power reproduction, and erasing or destruction of already recorded data that may be caused, in high-speed recording of a rewritable-type or write-once-type optical disc, when the linear velocity at the time of reproduction becomes slow, e.g. , in an access operation at the time of reproduction with a constant linear velocity and in a return operation from rotational stop due to a standby state.
