We analyse the Abelian N=1 super-Chern-Simons model coupled to
parity-preserving matter in linear and non-linear gauges with exact BRST
invariance. Then we analyse the theory in field/antifield formulation to
discuss the model at quantum level. Furthermore, we implement the
field/antifield dependent transformation parameter to generalize the BRST
symmetry of the theory. The novelty of field/antifield dependent BRST
transformation is that under change of variable the Jacobian of the functional
integral extends the quantum action from linear gauge to non-linear gauge. The
results are established in full generality.Comment: 7 pages, no figure, Version to appear in EP
