Title: Inspection of semiconductor device
Inventor: KOYA NOBUYUKI
IPC: H01L21/26
Filed: 1986-11-04
Abstract: PURPOSE:To expand a fine pinhole in a film enabling it to be detected by a microscopic observation by a method wherein a silicon nitride film on a semiconductor substrate is corroded with fluoronitric acid solution. CONSTITUTION:A silicon nitride film 1 is formed on the surface of a silicon substrate 3 through the intermediary of an extremely thin silicon oxide film 2. At this time, the silicon nitride film 1 is provided with a fine pinhole 4 hardly detected by an ordinary electron microscope. Therefore, when the silicon nitride film 1 is corroded with fluoronitric acid water solution, the pinhole 4 in the silicon nitride film 1 is expanded simultaneously corroding the extremely thin silicon oxide film 2 as well as the silicon substrate immediately below the film 2. The pinhole 4 in such an expanded state can be easily observed by the electron microscope, enabling the initial pinhole state to be estimated from the processed conditions thereof. Such a technology can be used to analyze and stabilize the formation process of silicon nitride film.

Abstract: PURPOSE:To prevent the tilting of a driven roller by providing a pair of supporting pieces, pivotally supporting both end parts of a driven roller respectively, and the bridging part, interconnecting the fellow vicinity parts of the pivotally supporting part for each supporting piece, to a spring member. CONSTITUTION:When a card 2 is inserted from an insertion port 3, the card 2 is carried toward the rear end of a casing 1 since a flat type motor 1 is rotated, a driving pulley 7 is driven, and the tip part of the card 2 is nippedly held repulsively between the linear part 9a of a belt 9 and the driven roller 18 in the port 3 side.

IPC: B66B1/40
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To improve removal of yarn defect and reduce yarn waste. SOLUTION: After generation of yarn defect, the length of yarn having defect is determined between the time of yarn defect generation and cutting-off. When a package roller 14 is rotated in a delivering direction, or when a winding package 4 is rotated in the delivering direction, the length of yarn which is delivered from the winding package 4 and enters a suction pipe 22 is detected after the yarn is inserted into a suction pipe 22 positioned on this side of the winding package 4 is detected by a sensor 28 positioned in the suction pipe 22.  Based on the length of the yarn which is first determined, a delivering process is stopped if the length of the yarn is sucked into the sucking pipe in such a length as the length of yarn wound continuously since the occurrence of the yarn defect stays at the outside of the yarn end part jointing device for cutting-off when the yarn on the winding package 4 side is inserted in a yarn end part jointing device 8 continuously.
