We study an inflationary model which can account for both hybrid inflation and a true vacuum with broken supersymmetry. For a weakly coupled inflaton field, the dynamics during the inflationary phase is determined by the supersymmetry breaking sector with scale M_S ~ 10¹⁰ GeV. The spectrum of density fluctuations is then almost scale invariant since the dominant effect comes from a linear term in the inflaton field. We also study the onset of the transition to a thermal state and the symmetry breaking taking place at the end of the inflationary phase.
