It is shown that the reservoir engineering can be controlled by the collective phase Phi of three coherent fields interacting with a closed Delta-type atom. We find that the atomic system acts as a one-channel dissipation reservoir when Phi = 0(pi), but it behaves as a two-channel dissipation reservoir for Phi not equal 0(pi). The phase-dependent reservoir engineering provides a convenient way to produce robust two-mode squeezing and entanglement, which may find potential applications in quantum information processing.
