Abstract:
A manufacturing method of an isolation structure includes the following steps. A semiconductor substrate is provided. A trench is formed in the semiconductor substrate. A first film forming process is performed to form a first dielectric layer conformally on the semiconductor substrate and conformally in the trench. An annealing process is performed to densify the first dielectric layer and convert the first dielectric layer into a second dielectric layer. A thickness of the second dielectric layer is less than a thickness of the first dielectric layer. A second film forming process is performed after the annealing process to form a third dielectric layer on the second dielectric layer and in the trench. The trench is filled with the second dielectric layer and the third dielectric layer.

Claim (Index 6):
The manufacturing method of the isolation structure according to  claim 1 , wherein the first dielectric layer, the second dielectric layer, and the third dielectric layer comprise silicon oxide layers respectively.
