An idempotent semigroup (band) is a semigroup in which every element is an idempotent. We describe the structure of idempotent semigroups in terms of semilattices Ω, partial chains Ω of left zero semigroups, and partial chains Ω of right zero semigroups. We also describe bands of maximal left zero semigroups in terms of partial chains Ω of left zero semigroups and semilattices Ω of right zero semigroups.
