I describe the universal phase diagram of 2D surface superconductor with generic Rashba interaction in a parallel magnetic field. In addition to uniform BCS state we found two inhomogeneous superconductive states, the stripe phase at high magnetic fields and a new "helical" phase which intervenes between BCS state and stripe phase at intermediate magnetic field and temperature. We prove that the ground state for helical phase carries no current.
