Title: Manufacture of semiconductor device
Inventor: OKAMURA KENJI
IPC: H01L21/768
Filed: 1986-07-23
Abstract: PURPOSE:To form an insulating film having high reliability, and to improve reliability and the degree of integration by shaping an silicate glass film onto a semiconductor substrate, containing boron in the surface and removing all of the silicate film containing boron by using a specific etching method. CONSTITUTION:An silicate glass film 14 is formed onto one main surface of a semiconductor substrate 11, and an silicate glass film 15 containing boron is shaped onto the surface of the silicate glass film 14 by thermally treating the substrate 11 in an atmosphere containing boron. The silicate film 15 including boron is all removed through etching by employing an etching method having a predetermined selection ratio to the silicate glass film. The phosphorus silicate glass (PSG) film 14 is used as the silicate glass film at that time. The phosphorus concentration of the PSG film 14 left through said each process is 8 wt. %, and no boron is included, thus resulting in no hygroscopicity and excellent reliability. The surface of the PSG film 14 can be smoothed through heat treatment at a comparatively low temperature such as 900 deg.C, thus realizing the improvement of the degree of integration and function of a semiconductor device.

IPC: G02B7/00
Filed: 1986-07-24
Abstract: PURPOSE:To improve the accuracy for adjusting an angle, by fixing a parallel ray generation source and a photodetecting part, and placing in series a lens system for concentrating parallel rays to one point, and a lens system for converting a light beam emitted from a point light source, to parallel rays, on a reference base for fixing a light source having a lens system. CONSTITUTION:Parallel rays which have been emitted from a helium neon laser tube pass through a pin hole 2, reflected by the end face of a lens 3 and return to said pin hole. By adjusting an inclination of the lens so that its return light is made incident exactly on the center of the pin hole, the parallel rays are made incident vertically on the lens. When the parallel rays are made incident on the lens 3 and condensed, and pass through a convergence point, subsequently, they diverge. When a lens 4 is placed in the opposite direction at a position being symmetrical to the lens 3 centering around the light beam convergence point, the diverging light beam is made incident on the lens 4 and becomes parallel rays. When a position adjustment of a reference base is executed, and the parallel rays which have passed through the lens 4 are made incident on a camera 5, and a beam is reflected on a reference position prescribed on a monitor 6, a position of the reference base is aligned.

Filed: 1988-07-13
Abstract: PURPOSE:To perform the optimum tracking servo to disks having different numbers of sectors by counting the number of tracking patterns of a disk and setting a calculated content to the servo constant corresponding to the number of sectors of the disk. CONSTITUTION:When a magnetic disk is rotated, a counter which counts servo signals D is initialized and the pattern of the servo signals is detected from the output of a comparator 14 by detecting index signals at every turn of the disk. The count value of the counter is increased by +1 whenever the pattern of the servo signals is detected. Then the number of sectors is discriminated at the next index signal detecting time and tracking servo is performed by setting the constant corresponding to the discriminated number of sectors. After discriminating the number of sectors, the sampling frequency of a head position controlling system is changed so that the sampling frequency can correspond to the detecting timing of the servo signal pattern and values of a head driving system and tracking error signal detecting system are optimized. At the time of optimization, a ROM in the CPU 15 is referred to. When such constitution is used, the tracking servo can be performed certainly by automatically detecting the number of sectors.
