Abstract:
A method for fabricating semiconductor device comprising the steps of: forming a first trench and a second trench in a substrate; forming a liner in the first trench and the second trench; forming a first patterned mask on the substrate to cover the second trench; removing the liner in the first trench; removing the first patterned mask; and forming an insulating layer in the first trench and the second trench to form a trap rich isolation structure in the first trench and a deep trench isolation structure in the second trench.

Claim (Index 8):
The method of  claim 1 , further comprising:\n forming the insulating layer in the first trench and the second trench after removing the first patterned mask: and performing a planarizing process to remove part of the insulating layer for forming the trap rich isolation structure and the deep trench isolation structure.
