    Abstract: Polishing compositions that can selectively and preferentially polish certain dielectric films over other dielectric films are provided herein. These polishing compositions include either cationic or anionic abrasives based on the target dielectric film to be removed and preserved. The polishing compositions utilize a novel electrostatic charge based design, where based on the charge of the abrasives and their electrostatic interaction (forces of attraction or repulsion) with the charge on the dielectric film, various material removal rates and polishing selectivities can be achieved.

    Abstract: Fluid processing apparatuses and systems are disclosed. In some embodiments the fluid processing apparatuses include a movable enclosure (38), a plurality of filter housings (30) disposed substantially within the movable enclosure (38), and a stand (36) disposed within the enclosure (38). The filter housings (46a; 47a; 48a) are in fluid communication with one another. Each filter housing (46a; 47a; 48a) defines an elongate path and is configured to support a respective filter (49) along the elongate flow path to filter a substantially continuous flow of fluid. The stand (36) supports each filter housing (46a; 47a; 48a) such that the elongate flow path of each filter housing (46a; 47a; 48a) is substantially parallel to a vertical axis, wherein each filter housing (46a; 47a; 48a) is independently rotatable, relative to the stand (36).

    Abstract: The disclosure provides chemical mechanical polishing compositions and methods for polishing polysilicon films with high removal rates. The compositions include 1) an abrasive; 2): Formula (I) at least one compound of structure (I): (I), 3) at least one compound of structure (II): Formula (II); and 4) water; in which the composition does not include tetramethylammonium hydroxide or a salt thereof. The variables n, R 1 -R 7 , X, Y, and Z 1 -Z 3 in structures (I) and (II) are defined in the Specification. The synergistic effect of the compounds of structures (I) and (II) in these chemical mechanical polishing compositions leads to high polysilicon films material removal rate during polishing.

    Abstract: The present disclosure provides chemical mechanical polishing compositions that achieve minimal dishing at reduced dishing reducer (DR) levels when compared to known CMP compositions. The compositions of the disclosure include a dynamic surface tension reducer (DSTR) which allows for lower levels of dishing reducer in the compositions. Indeed, the compositions of the disclosure allow for lower levels of dishing reducer to achieve the same dishing as known compositions having higher levels of dishing reducer. Deleterious effects of high DR levels are thereby avoided or minimized when employing the compositions of the disclosure.
