Title: Apparatus and methods for aligning a surface of an active retainer ring with a wafer surface for chemical mechanical polishing
Inventor: SALDANA MIGUEL ANGEL
IPC: B24B37/32
Filed: 2002-03-29
Granted: 2003-11-01
Abstract: A CMP system and methods reduce a cause of differences between an edge profile of a chemical mechanical polished edge of a wafer and a center profile of a chemical mechanical polished central portion of the wafer within the edge. The wafer is mounted on a carrier surface of a wafer carrier so that a wafer axis of rotation is gimballed for universal movement relative to a spindle axis of rotation of a wafer spindle. A retainer ring limits wafer movement on the carrier surface perpendicular to the wafer axis. The retainer ring is mounted on and movable relative to the wafer carrier. A linear bearing is configured with a housing and a shaft so that a direction of permitted movement between the wafer carrier and the retainer ring is only movement parallel to the wafer axis, so that a wafer plane and a retainer ring may be co-planar.

Title: Method of making structural cellular cores suitable use of wood
Inventor: SING PETER
IPC: B32B21/00
Filed: 2003-01-13
Granted: 2006-11-21
Abstract: The fundamental technique of the method for making cellular cores is to make stacks of components which are configured such that cutting slices off the stacks produces cellular cores and, when needed, components used in stacks used to produce cellular cores. One of the basic components used in the stacks is termed a ribbed ply which is a ply (thin sheet of material such as wood) with a number of ribs (long thin strips of material such as wood) attached to the ply, parallel to each other. If the spaces between the ribs are filled with filler material such foam plastic, the cells in the cellular core will be filled with the filler material. The filler material is introduced as layers of the material stacked alternately with plies and adhesively attached. Slices of such a stack, sliced parallel to the grain of the plies (if wood) are called ribbed fillers. Stacking ribbed fillers and plies produces a stack having a cross section which, when sliced, produces filled cell cellular cores.
