摘要： A semiconductor wafer chamfer polishing method for polishing chamfers formed on the edges of semiconductor wafers includes rotating a semiconductor wafer; pressing a polishing cloth against a chamfer of the semiconductor wafer with sufficient pressure to elastically deform the polishing cloth, while supplying polishing fluid to the chamfer; sliding the polishing cloth along an incline of the chamfer from an outer edge toward a center of the semiconductor wafer so as to form a bulge portion of the polishing cloth which contacts an outer surface of the semiconductor wafer, thereby polishing the outer surface along with the chamfer of the semiconductor wafer.

摘要： To take upright articles such as ampules out from a case for storage thereof, the case having a pair of laterally opposite side plates formed with a pair of vertical slots, respectively, which are provided with pointed protrusions, defining notches into which a shutter is removably engaged and thereby held in a posture inclined forward with respect to the transporting direction. A control device is adapted to disengage the shutter from the notches and then to engage the shutter into the other notches so as to erect the shutter. A front ejector plate is inserted into the case and the shutter is removed by a chuck from the case. A pusher plate provided on the inner side of a case rear side plate pushes the ampules forward and the rear ejector is inserted into the case. Then a device for moving the front and rear ejector plates is actuated horizontally and thereby the upright articles are transported onto a conveyor. A case feeding station is provided with a feeding conveyor and a case discharging station is adapted to discharge the empty case having completed transport of the upright articles.

摘要： A manufacturing method for an alkyldihalogenophosphine uses an alkyl halide and a trihalide of phosphorus as starting materials. A reaction product which is formed by an FC reaction is reduced by yellow phosphorus in the presence of iodine, whereby an alkyldihalogenophosphine is manufactured. A high-purity alkyldihalogenophosphine can be manufactured with a high yield by using an excess amount of a trihalide of phosphorus, which can act as a reaction solvent.
