摘要:
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.

A substrate having a first transistor on a first region, a second transistor on a second region, a trench isolation region, a resistor-forming region is provided.

The resistor material layer is isotropically etched. A second ILD layer is formed over the substrate. The second ILD layer and the first ILD layer are patterned with a mask and the first hard mask pattern to form a contact opening.

A method of forming a semiconductor device is provided. A material layer, a first flowing material layer and a first mask layer are sequentially formed on a substrate. A first etching process is performed by using the first mask layer as a mask, so as to form a first opening in the material layer. The first mask layer and the first flowing material layer are removed. A filler layer is formed in the first opening. A second flowing material layer is formed on the material layer and the filler layer. A second mask layer is formed on the second flowing material layer. A second etching process is performed by using the second mask layer as a mask, so as to form a second opening in the material layer.
