In this short note we associate a de Rham bundle to a nilpotent Higgs bundle over $X_0$ of exponent $n\\leq p-1$ via the exponential function. Presumably, the association is equivalent to the inverse Cartier transform of A. Ogus and V. Vologodsky for these Higgs bundles. However this point has not been verified in the note. Instead, we show the equivalence of the association with that of Sheng-Xin-Zuo in the geometric case.
