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 for fabricating semiconductor device is disclosed. 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. A first ILD layer covers the first region, the second region, and the resistor-forming region. A resistor material layer and a capping layer are formed over the first region, the second region, and the resistor-forming region. The capping layer and the resistor material layer are patterned to form a first hard mask pattern above the first and second regions and a second hard mask pattern above the resistor-forming region. 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.
