The invention relates to methods and materials for controlling stability and color intensity in an electrophoretic display element. Filler particles in the electrophoretic display element, serves as a medium that the electrophoretic particles must travel through during switching between optical states of the display. The filler particles provide improved control over the color intensity of the electrophoretic display element. In addition, the filler particles create resistance to the migration of the electrophoretic particles, thereby improving the bistability of the electrophoretic displays and inhibiting settling of the electrophoretic particles. Also, migration resistance provided by the filler particles can enable threshold addressing of an electrophoretic display.

Tools for conditioning chemical mechanical planarization (CMP) pads comprise a substrate with abrasive particles coupled to at least one surface. The tools can have various particle and bond configurations. For instance, abrasive particles may be bonded (e.g., brazed or other metal bond technique) to one side, or to front and back sides. Alternatively, abrasive particles are bonded to a front side, and filler particles coupled to a back side. The abrasive particles can form a pattern (e.g., hexagonal) and have particle sizes that are sufficiently small to penetrate pores of a CMP pad during conditioning, leading to fewer defects on wafers polished with the conditioned CMP pad. Grain bonding can be accomplished using brazing films, although other metal bonds may be used as well. Also, balanced bond material (e.g., braze on both sides) allows for low out-of-flatness value.
