Abstract: PURPOSE:To make spin coating and resin curing with high efficiency by supporting plural rotating units which are rotationally driven while supporting plural optical disks and conveying the disks between a spin coating unit and resin curing unit. CONSTITUTION:The optical disk 21 is rotated at a low speed and the resin is sprayed from a nozzle 46 in the stage of forming a protective film consisting of the transparent resin on the recording surface of the optical disk. The disk 21 is thereafter rotated at a high speed and the resin is radially diffused, by which the resin is uniformly spin-coated on the disk.

Filed: 1987-11-25
Abstract: PURPOSE:To detect a peak even in case the peak has a level approximately equal to that of the noise by adding the members proportional to the 4-power value of the density of a subject picture element to two members of a picture energy function and performing the smoothing and emphasizing actions so as to secure the max. probability caused by the picture energy. CONSTITUTION:The source picture data is smoothed so as to secure the max. probability that is decided by the picture energy including a member where the differentiation related to the density of each subject picture element is proportional to the density Laplacean obtained at a subject position and a member proportional to the square of density of the noise at each subject. Then, the new picture energy is obtained by adding a member proportional to the 4-power value of the density of the subject picture element to the old picture energy. The source picture data is changed so that the probability decided by the new picture energy is max. and the low frequency component is emphasized to attain the binarization without using the threshold value. Then, a peak position is detected in a picture. Thus, the peak can be detected even with such a picture that has its peak approximately equal to the level of the noise and has the hardship to set the threshold value.

Filed: 1987-11-24
Abstract: PURPOSE:To display a gettering effect with good reproducibility during a wafer process, by performing high temperature heat treatment of a semiconductor substrate in three stages, while restricting a temperature ranges and times. CONSTITUTION:A silicon substrate, which is formed by a Czochralski method is kept for, e.g., 30 minutes at a high temperature (a), e.g., 1,280 deg.C, which is selected in the range of 1,200-1,400 deg.C. During this period, Oxygen in the surface of the silicon substrate is excluded to the outside. Oxygen atoms in the crystal become atom states. Many intrinsic point defects are yielded. Then the temperature is decreased to about 700 deg.C at the temperature decreasing speed of 40-1,000 deg.C/min. The substrate is kept for 1-10hours, e.g., 8hours. During this period, defects in the surface layer of the silicon substrate are completely cured, and nucleuses are deposited and formed in the crystal. Then the substrate is kept at the intermediate temperature (c) of about 1,000 deg.C for more than 10 minutes, e.g., 8hours. The deposited nucleuses are grown into the nucleuses, which become the cause of an intrinsic gettering effect in the next high temperature step.
