摘要： A polishing device is formed of a pair of rotatable and elevatable upper supporting members provided with ring shape polishing pads at lower surface peripheries thereof, a pair of rotatable lower supporting members provided with ring shape polishing pads at upper surface peripheries thereof, a rotatable and elevatable disc holding device for holding a disc to be polished, and an arm for supporting the upper supporting members and the disc holding device. The polishing device further includes driving devices for rotating the upper supporting members, the lower supporting members and the disc holding device, respectively. The disc is independently rotated in a direction opposite to a rotating direction of the upper and lower supporting members to improve polishing efficiency. By setting rotating speeds of the supporting members and the disc, a regular working mark can be formed on the disc.

摘要： A specular machining apparatus for giving a specular machining or mirror-like surface to a peripheral edge portion, in particular a chamfered portion, of typically a semiconductor wafer such as a silicon wafer. This mirror-like surface is provided to smooth out the relatively rough surface formed by etching to remove a strained layer which is generated as a result of grinding work. The mirror-like surface tends to reject the attachment of dirt, which is desirable. The specular machining apparatus is of simple construction and easy to use, comprising a chuck table plus chuck means for holding a wafer having a chamfered peripheral edge portion. The chuck table rotates the wafer held by the chuck about the wafer axis. A polishing ring is disposed to be freely rotatable around an axis perpendicular to the axis of the wafer on the chuck table, to permit the polishing surface on the outer periphery to be accessable for polishing.

摘要： Described herein is a flat lapping machine capable of precision-abrading simultaneously flat surfaces on the front and rear sides of a work in the fashion of lapping, polishing and grinding machines. The present invention contemplates to provide a flat lapping machine which is simplified in construction as compared with conventional flap lapping machines having a large number of carriers in planetary motions, and which can stop the respective carriers easily in specific positions and directions at the end of a lapping operation. To this end, the present invention employs a large number of support gear mechanisms each constituted by a plural number of small gears and located at uniform intervals around a center gear, rotatably supporting the respective carriers in predetermined positions while the respective carriers are driven by the center gear.
