Filed: 1985-02-19
Abstract: PURPOSE:To enable to form high-precision resist patterns having a good dry etching resistance by a method wherein the dry etching resistance of the coated layer is specified. CONSTITUTION:A polymethyl methacrylate film is applied on the substrate to be treated, whereon a polycrystalline Si film A is formed, as a resist having a high-resolving power and a slightly weak dry etching resistance, a pattern is drawn using an electron beam drawing device and a developing is performed, whereby inversion resist patterns 12 are formed.

Title: Optical information reader
Inventor: TATSUMI KENJI
IPC: G11B7/09
Filed: 1984-02-21
Abstract: PURPOSE:To attain a focusing action with high accuracy and high sensitivity by setting a 4-split photodetector at the focal position of a convex lens and differentiating the output of the photodetector produced by the variation of the spot size on said photodetector. CONSTITUTION:A photodetector 8 is set at the focal position of a convex lens 7, and the photodetecting surface of the detector 8 contains four detectors 8c-8f. A detector 8a consisting of detectors 8e and 8f and a detector 8b consisting of detectors 8c and 8d are divided concentrically into two parts in the right and left sides respectively. Thus both detectors 8a and 8b work independently of each other. Therefore the incident light quantity of detectors 8c and 8d is smaller than that of detectors 8e and 8f at the focal position. This gives virtually no effect to the information signal 19 despite the disturbance of the focus signal. Furthermore an offset is reduced since the differential output is used as a focus error signal. At the same time, the focusing sensitivity is improved.
