A CMP slurry composition for polishing a boron silicon (B—Si) compound may include a catalyst, an abrasive including a plurality of particles and being configured to polish the boron silicon (B—Si) compound, and a pH adjuster. The CMP slurry composition may further include an oxidizer. The catalyst may have a binary catalyst configuration comprising a first catalyst material and a second catalyst material. The first catalyst material may include Fe, and the second catalyst material may include Cu. The oxidizer may include hydrogen peroxide (HO). A CMP (chemical mechanical polishing) method for a boron silicon (B—Si) compound may include providing a substrate structure including a thin film formed of the boron silicon (B—Si) compound and performing a CMP process on the thin film. The CMP process is performed by using the CMP slurry composition.
