Abstract:
A semiconductor device structure and a method for forming the same are provided. The semiconductor device structure includes a first fin structure protruding from the first region of the semiconductor substrate and having a first portion and a second portion over the first portion. The semiconductor device structure also includes a liner structure including a first insulating liner layer and second insulating liner layer. The first insulating liner layer has a bottom portion covering the semiconductor substrate and a sidewall portion covering a sidewall of the first portion of the first fin structure. The second insulating liner layer is over the bottom portion and the sidewall portion of the first insulating liner layer and extends on a top surface of the sidewall portion of the first insulating liner layer. The semiconductor device structure also includes an isolation feature over the liner structure.

Claim (Index 21):
A method for forming a semiconductor device structure, comprising:\n patterning a semiconductor substrate to form a first structure, a second fin structure adjacent to the first fin structure, and a trench between the first structure and the second fin structure, wherein the first fin structure has a channel region formed of a material that is different from a material of the first fin structure outside of the channel region; conformally forming a first insulating liner layer to cover sidewalls and a bottom of the trench, wherein a portion of the first insulating liner layer that covers the sidewalls of the trench has a top surface below a bottom of the channel region of the first fin structure; conformally forming a second insulating liner layer over the first insulating liner layer in the trench, such that the top surface of the portion of the first insulating liner layer is covered by the second insulating liner layer; and forming an isolation feature over the second insulating liner layer in the trench.
