摘要:
A manufacturing method of a semiconductor device includes the following steps. Firstly, a lower electrode is formed over a substrate (semiconductor substrate). Successively, the lower electrode is primarily crystallized. Successively, a capacitance dielectric layer is formed over the lower electrode after primarily crystallized. Successively, the capacitance dielectric layer is secondarily crystallized. Then, an upper electrode is formed over the capacitance dielectric layer.
