  The q-deformed statistical mechanics for fermions has been used to
investigate the Thomas-Fermi screening length at finite temperature.
Considering linear response, the calculations have been made at weakly
nondegenerate regime. The results show that q-deformation has significance
effects on screening length at higher temperatures. It is also shown that the
q-deformation effects vanish at zero temperature limit. One can find that more
correction terms of deformation have more effects on screening length. The
bahaviour of screening length is different for different values of q.
