Let $S$ be an inverse semigroup with the set of idempotents $E$. In this paper we define the module super-amenability of a Banach algebra which is a Banach module over another Banach algebra with compatible actions, and show that when $E$ is upward directed and acts on $S$ trivially from left and by multiplication from right, the semigroup algebra $ \ell ^{ 1}(S)$ is $\ell^{ 1}(E)$-module super-amenable if and only if an appropriate group homomorphic image of $S$ is finite.
