Abstract: A method for fabricating semiconductor device preferably forms a stop layer composed of amorphous silicon between a first BM layer and a second BBM layer of one of the gate structure during the fabrication of a device having multi-VT gate structures. By doing so, it would be desirable to use the stop layer as a protecting layer during the etching process of work function metal layers and the second BBM layer so that the first BBM layer could be protected from etchant such as SC1 and the overall thickness of the first BBM layer and the performance of the device could be maintained.

Abstract: A method of forming a semiconductor device includes following steps. Firstly, a substrate having a transistor is provided, where the transistor includes a source/drain region. A dielectric layer is formed on the substrate, and a contact plug is formed in the dielectric layer to electrically connect the source/drain region. Next, a mask layer is formed on the dielectric layer, where the mask layer includes a first layer and a second layer stacked thereon. After this a slot-cut pattern is formed on the second layer of the mask layer, and a contact slot pattern is formed on the first layer of the mask layer. Finally, the second layer is removed and a contact opening is formed by using the contact slot pattern on the first layer.
