Summary
We present the difference of chemical freeze-out parameters $T_{\textrm{ch}}$ and $\mu_B$ between the statistical analysis of hadron yield with or without (anti-)deuteron yield at RHIC. The chemical freeze-out temperature $T_{\textrm{ch}}$ become lower if the fit include the (anti-)deuteron, which might hint (anti-)deuteron and proton freeze-out early than strange hadrons. The producing mechanism of deuteron production will be also discussed.
