Semiconductor fabrication methods thereof
A method for fabricating a semiconductor structure includes providing a substrate including isolation regions and a device region between adjacent isolation regions; forming a plurality of fin structures, including a first plurality of fin structures on the isolation regions and a second plurality of fin structures on the device region of the substrate; forming an isolation layer, having a top surface lower than top surfaces of the fin structures, on the substrate between adjacent fin structures; etching the first plurality of fin structures on the isolation regions after forming the isolation layer; and forming a gate structure across the second plurality of fin structures on the device region after etching the first plurality of fin structures formed on the isolation regions. The gate structure covers a portion of sidewall and top surfaces of each fin structure of the second plurality of fin structures on the device region.
