  The growth of a rough and porous thin surface by deposition of randomly
shaped clusters with different sizes over an initially flat linear substrate is
simulated, using Monte Carlo technique. Unlike the ordinary Random Deposition,
our approach results in aggregation of clusters which produces a porous bulk
with correlation along the surface and the surface saturation occurs in long
enough deposition times. The scaling exponents; the growth, roughness, and
dynamic exponents are calculated based on the time scale. Moreover, the
porosity and its dependency to the time and clusters size are also calculated.
We also study the influence of clusters size on the scaling exponent, as well
as on the global porosity.
