Abstract

A manufacturing method of a semiconductor structure includes the following steps. A high-k dielectric layer is formed on a semiconductor substrate, and a barrier layer is formed on the high-k dielectric layer. An oxygen annealing treatment is performed after the step of forming the barrier layer; and a capping layer is formed on the barrier layer after the oxygen annealing treatment.
