Commutative Algebra, chapter V, § 2. The lift of prime ideals

With the hypotheses and notation of Corollary 2, if AA is semi-local, so is A′A'.

For every maximal ideal m′m' of A′A', m′∩Am' \cap A is a maximal ideal of AA (no. 1, Proposition 1); the corollary then follows from Corollary 2, since by hypothesis the set of maximal ideals of AA is finite.

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
