摘要:
A method of fabricating an isolation shallow trench contains providing a substrate with at least a deep trench, forming a cap layer on the upper portion of the deep trench, forming a crust layer on a portion of the cap layer, defining a trench extending through the cap layer and the conductive layer, and forming an isolation layer in the shallow trench.
