Abstract: A manufacturing method of a semiconductor device includes the following steps. First patterned structures are formed on a substrate. Each of the first patterned structures includes a first semiconductor pattern and a first bottom protection pattern disposed between the first semiconductor pattern and the substrate. A first protection layer is formed on the first patterned structures and the substrate. A part of the first protection layer is located between the first patterned structures. A first opening is formed in the first protection layer between the first patterned structures. The first opening penetrates the first protection layer and exposes a part of the substrate. A first etching process is performed after forming the first opening. A part of the substrate under the first patterned structures is removed by the first etching process for suspending at least a part of each of the first patterned structures above the substrate.

Abstract: A method of performing an etching process is provided. A substrate is provided, wherein a first region and a second region are defined on the substrate, and an overlapping region of the first region and the second region is defined as a third region. A tri-layer structure comprising an organic layer, a bottom anti-reflection coating (BARC), and a photoresist layer is formed on the substrate. The photoresist layer and the BARC in the second region are removed. An etching process is performed to remove the organic layer in the second region by using the BARC and/or the photoresist layer as a mask, wherein the etching process uses an etchant comprises CO2.
