Title: Carrier head design for chemical mechanical polishing apparatus
Inventor: ZUNIGA STEVEN M
IPC: B24B37/30
Filed: 2003-03-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a carrier head that can apply substantially uniform pressure over the entire surface of a substrate to be polished.  <P>SOLUTION: The carrier head uses a pressure chamber and a floating gimbal. The floating gimbal allows a carrier base to rotate with respect to a driving shaft, and no downward force is applied to the substrate through the gimbal at this time. Instead, a rolling diaphragm seals the carrier base to a carrier housing to form a chamber. By pressurizing the chamber, an even load can be applied across the chamber. A retaining ring is independently loaded by an inflatable bladder. Torque is transferred from the carrier housing to the carrier base by two horizontal pins positioned near the substrate. The pins can slide vertically in the housing, but not laterally. However, there is sufficiently elasticity to allow the torque pins to comply with manufacturing tolerances so that both torque pins bear the rotational load.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a ceramic material excellent in wear resistance, and to provide a rolling bearing that has a long rolling fatigue life time and is rich in reliability by using this material.  <P>SOLUTION: At least one of sliding components (an inner ring 1, an outer ring 2 or a ball 3) constituting the rolling bearing is composed of the ceramic material which comprises silicon nitride as the main phase. These ceramic sliding components are set so that the area of a virtual circle inscribed with a grain boundary glass phase area existing on each plane surface of the sliding components becomes less than 2 μm<SP>2</SP>when the components are cut at any plane surface. That is, the ceramic sliding components do not include a large agglomerate moiety of the grain boundary on its surface or inner part, which is relatively weak in attrition. The above structure can provide the rolling bearing which has a long rolling fatigue life time and is rich in reliability whatever the ratio of the grain boundary glass phase or the adding proportion of a sintering aid is.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
