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.
