Abstract
An integrated circuit structure includes a semiconductor substrate, which includes a semiconductor strip. A Shallow Trench Isolation (STI) region is on a side of the semiconductor strip. The STI region includes a first portion comprising an oxide and a second portion free from oxide. The second portion separates the first portion from the semiconductor substrate. A semiconductor fin is over and aligned to the semiconductor strip, wherein the semiconductor fin is higher than a top surface of the STI region.
