Polishing compositions and methods of use thereof |
| 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) at least one compound of structure (I):3) at least one compound of structure (II):and 4) water; in which the composition does not include tetramethylammonium hydroxide or a salt thereof. The variables n, R1-R7, X, Y, and Z1-Z3 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. |
