IPC: H01L21/306
Filed: 1988-10-19
Abstract: PURPOSE:To eliminate the dispersion of oblique angles in a taper part thereby enabling specific taper part to be formed easily and without fail by a method wherein a nitride film is coat-formed on an insulating film formed on a semiconductor substrate and after patterning the nitride film, the insulating film is selectively wet-etched through the intermediary of the nitride film. CONSTITUTION:A nitride film in specific thickness is coat-formed on an insulating film 2 formed on a semiconductor substrate 1 and after patterning the nitride film 7, the insulating film 2 is selectively wet-etched using the nitride film 7. For example, after forming the SiO2 insulating film 2 on the semiconductor substrate 1, the surface layer is ion-implanted to form a PSG layer 6 while the surface is coated with the nitride film 7 300-1000Angstrom  thick by LPCVD process. Next, after coating the nitride film 7 with photoresist to be patterned, the nitride film 7 is dry-etched to be patterned conforming to a resist pattern 8. Finally, when the insulating film 2 is wet-etched through the intermediary of the pattern of the nitride film 7, the etched amount is increased on the surface to form a taper part 2f.

Abstract: PURPOSE:To stably move a head carriage with high accuracy by providing a driving transmitting means for moving the head carriage in the radius direction of a recording medium and a means for forcibly regulating a part of the transmitting means within a specified range. CONSTITUTION:A disk D is inserted into a spindle 2 and a stepping motor 12 rotates a cam 8 counterclockwise to move the head carriage 3 toward the inner periphery of the disk with the energizing force of a spring. A lever 11 is pressed by the projection 8d of the cam 8 near a reference tracking position on the innermost periphery and turned counterclockwise to cross a photointerrupter 16. The projection 8c of the cam 8 abuts on the stopper 17b of a protection plate 17 and locks it. It is known from an output from the interrupter that a head 4 arrives at the innermost peripheral track.

Abstract: PROBLEM TO BE SOLVED: To reduce the load of a work by heating and vaporizing sampled liquefied natural gas(LNG) at an atmospheric temperature, and analyzing it properly after storing it in a cylinder for a while. SOLUTION: LNG, flowing in an atmospheric-temperature vaporizing coil part 10 from a sampling nozzle 2, is vaporized at an atmospheric temperature, and the vaporized gas is stored in a cylinder 6 for a while, and thereafter analyzed properly.

Title: Detection of disappearance of solid layer, single crystal growth method using the same and device for the same growth metiiod
Inventor: KAWANISHI SHOROKU
IPC: C30B15/20
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To provide the detection at the time of growing a single crystal, the single crystal growth method that enables growth of a homogeneous single crystal and the device used for performing the single crystal growth method. SOLUTION: In this single crystal growth method and the device for the growth method, a transparent window 11 having an about 5mm diameter is formed at the center of the bottom of a quartz crucible 1 and a sensor part 12 of an optical temp. indicator is placed in the vicinity of the window 11. By using e.g. Acufiber(R) (manufacturer: NIKKO KEISOKU System K.K., Japan) as the optical temp. indicator, a 0.01 deg.C resolving power can be obtained and also, a temp. in the range of up to 1,900 deg.C can be measured. With the growth of a single crystal 8, the thickness of a solid layer 9 is reduced and finally, the solid layer 9 disappears. At this time, a drop in indicated temp. that is an apparent single crystal raw material temp. measured at the bottom of the crucible 1, occurs. By this temp. measurement, disappearance of the solid layer 9 can be detected. When the single crystal pulling-up operation is continued under the same conditions, the actual temp. within a melt is raised and the single crystal diameter is reduced. Therefore, when disappearance of the solid layer 9 is detected, control operations such as reducing the heater power, increasing the rotational speed of the crucible 1, decreasing the single crystal pulling-up speed, etc., are performed.
