Abstract:
A semiconductor structure includes a semiconductive substrate including a first surface and a second surface opposite to the first surface, a shallow trench isolation (STI) including a first portion at least partially disposed within the semiconductive substrate and tapered from the first surface towards the second surface, and a second portion disposed inside the semiconductive substrate, coupled with the first portion and extended from the first portion towards the second surface, and a void enclosed by the STI, wherein the void is at least partially disposed within the second portion of the STI.

Claim (Index 17):
A method of manufacturing a semiconductor structure, comprising:\n receiving a substrate; removing a first portion of the substrate to form a first recess; disposing a mask layer over the substrate and along a sidewall of the first recess and a bottom surface of the first recess; removing a portion of the mask layer disposed over the bottom surface of the first recess; removing a second portion of the substrate exposed from the mask layer to form a second recess; removing the mask layer; filling the first recess and the second recess by an oxide material, and forming a void at least partially disposed within the second recess.
