In this paper, we study the notion of ϕ-biflatness for some Banach algebras, where ϕ is a non-zero multiplicative linear functional. We show that the Segal algebra S(G) is left ϕ-biflat if and only if G is amenable. Also, we characterize left ϕ-biflatness of semigroup algebra ℓ1(S) in the term of biflatness, where S is a Clifford semigroup.
