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 32):
A method of manufacturing a semiconductor structure, comprising:\n removing a first portion of a substrate to form a first recess, the first recess having a first width at a top surface and a second width defined by a bottom surface of the first recess, the first width greater than the second width; depositing a mask layer along a sidewall of the first recess and the bottom surface of the first recess; etching the mask layer to expose a first region of the bottom surface of the first recess, wherein a second region of the bottom surface and a third region of the bottom surface are covered with the mask layer after the etching, and wherein the first region interposes the second region and the third region; etching the first region of the bottom surface of the first recess to form a second recess connected to the first recess and extending into the substrate while the mask layer is disposed on the second region and the third region; removing the mask layer along the sidewalls and the second region and third region of the bottom surface of the first recess; and depositing a dielectric material in the first recess and the second recess, wherein the dielectric material interfaces with the second region and the third region of the bottom surface of the first recess.
