    摘要: A method for fabricating MOS transistor includes the steps of: overlapping a second stress layer on an etching stop layer and a first stress layer at a boundary region of the substrate; forming a dielectric layer on the first stress layer and the second stress layer; performing a first etching process to partially remove the dielectric layer for exposing a portion of the second stress layer at the boundary region; performing a second etching process to partially remove the exposed portion of the second stress layer for exposing the etching stop layer; performing a third etching process to partially remove the exposed portion of the etching stop layer for exposing the first stress layer at the boundary region; and performing a fourth etching process partially remove the exposed portion of the first stress layer.

    摘要: A stacked structure for patterning a material layer to form an opening pattern with a predetermined opening width in the layer is provided. The stacked structure includes an underlayer, a silicon rich organic layer, and a photoresist layer. The underlayer is on the material layer. The silicon rich organic layer is between the underlayer and the photoresist layer. The thickness of the photoresist layer is smaller than that of the underlayer and larger than two times of the thickness of the silicon rich organic layer. The thickness of the underlayer is smaller than three times of the predetermined opening width.

    摘要: First, a semiconductor substrate having a first active region and a second active region is provided. The first active region includes a first transistor and the second active region includes a second transistor. A first etching stop layer, a stress layer, and a second etching stop layer are disposed on the first transistor, the second transistor and the isolation structure. A first etching process is performed by using a patterned photoresist disposed on the first active region as a mask to remove the second etching stop layer and a portion of the stress layer from the second active region. The patterned photoresist is removed, and a second etching process is performed by using the second etching stop layer of the first active region as a mask to remove the remaining stress layer and a portion of the first etching stop layer from the second active region.
