Suppose that $F$ is a finite field and $R=M_n(F)$ is the ring of $n$-squarematrices over $F$. Here we characterize when the Cayley graph of the additivegroup of $R$ with respect to the set of invertible elements of $R$, called theunitary Cayley graph of $R$, is well-covered. Then we apply this tocharacterize all finite rings with identity whose unitary Cayley graph iswell-covered or Cohen-Macaulay.
