  Feynman amplitudes of light-cone gauge string field theory for Type II
superstrings are shown to be equivalent to those of the covariant first
quantized formulation. In order to regularize the contact term divergences, we
consider the theory in a linear dilaton background
$\Phi_{\mathrm{dilaton}}=-iQX^{1}$. We show that the scattering amplitudes are
correctly reproduced in the limit $Q\to0$, even with Ramond sector external
lines.
