We study the problem of a thin film of neutral fermions in the presence of a magnetic field and scattering on random, uncorrelated irregularities at the boundaries of the film. An attractive interaction of s-wave type is assumed. We solve the equation for the energy gap and demonstrate its dependence on both the field and the scattering strength. The phase diagram is found. There exists a critical point (T_{c}^{*}, H_{c}^{*}). For temperatures below T_{c}^{*} the phase transition is of the first order and of the second order above it. As expected, the surface scattering significantly reduces the values of the critical field and temperature T_{c}. The critical point changes its position with increasing scattering rate but is not removed from the phase diagram until superfluidity is destroyed.
