This thesis presents the search for neutral Minimal Supersymmetric extension of Standard Model(MSSM) Higgs bosons decaying to tau pairs where one of the taus decays leptonically, and the other one hadronically. CDF Run II data with ${\cal L}_{int}~=~310~pb^{-1}$ are used. There is no evidence of MSSM Higgs existance, which results in the upper limits on $\sigma(p\bar{p} \to \phi)\times BR(\phi \to \tau\tau)$ in $m_A$ range between 115 and 250~GeV. These limits exclude some area in $\tan\beta$ vs. $m_A$ parameter space.
