A robotic force/torque (FT) sensor restricts the conduction of heat, generated by an attached tool, through the FT sensor body to a radial direction. Heat from the tool is channeled to the center of the FT sensor body by a thermally conductive member. Additionally, heat from the tool is insulated from portions of the FT sensor body other than its center by a thermally insulating member. Transducers, such as strain gages attached to the surfaces of deformable beams, are disposed at a substantially equal distance from the center of the FT sensor body. Accordingly, as heat conducts through the FT sensor body from the center radially outwardly, all transducers experience substantially equal thermal load at any given time. Embodiments of the present invention substantially eliminate thermal gradients across groups of transducers that are wired in differential circuit topologies, such as half-bridge or quarter-bridge, enhancing the ability of such circuits to reject a common-mode signal component caused by thermal changes to the FT sensor body or the transducers themselves. Elimination of thermal gradients in the FT sensor body, other than one in the radial direction, enhances the effectiveness of known temperature compensation techniques.

The invention provides a method for polishing or planarizing a substrate. First, the method comprises attaching a polymer-polymer composite polishing pad to a polishing device. The polishing pad has a polymer matrix and fluoropolymer particles embedded in the polymeric matrix. The fluoropolymer particles have a zeta potential more negative than the polymeric matrix. Cationic particle-containing slurry is applied to the polishing pad. Conditioning the polymer-polymer composite polishing pad exposes the fluoropolymer particles to the polishing surface and creates fluoropolymer-containing debris particles in the slurry. Polishing or planarizing the substrate with the increased electronegativity from the fluoropolymer at the polishing surface and in the fluoropolymer-containing debris particles stabilizes the cationic particle-containing slurry to decreases the precipitation rate of the cationic particle-containing slurry.
