Abstract
The present disclosure provides a method of manufacturing a semiconductor structure. A substrate is provided. A multi-layer structure is formed over the substrate, wherein the multi-layer structure includes a semiconductive material layer and an oxide layer over the semiconductive material layer. The oxide layer is patterned to form a first patterned layer. A second patterned layer is formed on the semiconductive material layer and alternately arranged with the first patterned layer. A first etching operation is performed on the substrate using a comprehensive pattern of the first patterned layer and the second patterned layer.
