<P>Herein, the corrosion behaviors of W metal gates in the presence of H<SUB>2</SUB>O<SUB>2</SUB> at the acidic medium were investigated as a function of dipping time, temperature, and H<SUB>2</SUB>O<SUB>2</SUB> concentration. We determined the kinetic constants (i.e. <I>k</I><SUB>w</SUB> and <I>k</I><SUB>h</SUB>) based on the experimental data. The activation energy (<I>E</I><SUB>a</SUB>) are calculated from the Arrhenius equation. Thermodynamic parameters (Δ<I>G</I><SUP>‡</SUP>, Δ<I>H</I><SUP>‡</SUP>, and Δ<I>S</I><SUP>‡</SUP>) for the dissolution were determined based on the Eyring plot. These results investigated in this study will provide researchers the prior information on parameters to control the corrosion behaviors of W metal gates during the chemical mechanical planarization (CMP) process.</P>
