Abstract: A polishing apparatus is used for polishing a workpiece such as a semiconductor wafer to a flat mirror finish. The polishing apparatus comprises a turntable having a polishing surface, a top ring for holding a workpiece and pressing the workpiece against the polishing surface to polish the workpiece, at least three cleaning apparatuses for cleaning polished workpieces, and a transfer structure for transferring the polished workpieces between at least three cleaning apparatuses. The polishing apparatus further includes a rotary transporter disposed in a position which can be accessed by said top rings and having a plurality of portions positioned on a predetermined circumference from a center of rotation of the rotary transporter for holding the workpieces.

Abstract: A multi-head type polishing apparatus includes a polishing table having a polishing surface, a plurality of top rings for holding workpieces and pressing the workpieces against the polishing surface, and a carousel for supporting the top rings and indexing the top rings. The polishing apparatus further includes a rotary transporter disposed in a position which can be accessed by the top rings, and having a plurality of portions positioned on a predetermined circumference from a center of rotation of the rotary transporter for holding the workpieces. The polishing apparatus also has a pusher for transferring the workpieces between the rotary transporter and the top rings.

Abstract: A portion of an ink jet recording head, which is formed by silicon material of a silicon substrate, is used as nozzles, ink chambers and a portion of an ink supply passage for supplying ink to the ink chambers and the remaining ink supply passage is formed of other material than the silicon material and connected to the portion of the ink jet recording head formed of the silicon material. A plurality of ink jet recording heads are formed as a unit block by a semiconductor fabrication process and cut out from a silicon substrate in block unit.
