摘要： A truing apparatus for a wafer polishing pad is provided which is capable of obtaining a sufficient truing effect while keeping the polishing amount of a polishing pad to a maximum. The truing apparatus includes a truing grinding wheel having an abrasive grain layer having ultra-abrasive grains electrodeposited thereon, a support arm for rotatably supporting the truing grinding wheel by bringing the polishing surface of an electrodeposition abrasive grain layer into abutment with the polishing pad, a grinding wheel rotary motor for rotating the grinding wheel, a self-aligning bearing disposed between a grinding wheel support plate and a grinding wheel rotation shaft, and pure water supply means for supplying pure water from the inside of the truing grinding wheel. The outer diameter of the grinding wheel is greater than the outer diameter of the wafers W, and the polishing surface of the grinding wheel is brought into abutment with the polishing pad over the overall width of one circumferential portion of a wafer polishing area. The grain size of the ultra-abrasive grains is preferably set at #60 to #230.

摘要： A cutting apparatus comprises an endless chain body comprising a plurality of plate-like flaps connected to each other for angular movement in a common plane. Each flap has an end face on an inner peripheral side of the chain body, and at least a part of the flaps having a cutting device at the end face. The apparatus further comprises a plurality of sprockets supporting the chain body in tension, and defining a common plane of cut effected by the combination of the chain body and the sprockets. The chain body is supported by a rigid backplate, of thickness not greater than the thickness of the flaps. It provides a firm support to the rotating chain body to permit sliding movement of the chain body within the common plane of cut. The apparatus further comprises a means for activating the rotational movement of the sprockets in cooperation with the chain body, and a means for moving an object or the chain body toward each other to effect removal of a material disposed within the extended plane of the common plane of cut to effect separation of an object into severed sections.
