  • Patent number: 8981527
    Abstract: A method for forming a resistor integrated with a transistor having metal gate includes providing a substrate having a transistor region and a resistor region defined thereon, forming a transistor having a polysilicon dummy gate in the transistor region and a polysilicon main portion with two doped regions positioned at two opposite ends in the resistor region, performing an etching process to remove the polysilicon dummy gate to form a first trench and remove portions of the doped regions to form two second trenches, and forming a metal gate in the first trench to form a transistor having the metal gate and metal structures respectively in the second trenches to form a resistor.

  • Patent number: 8841181
    Abstract: A method for fabricating a semiconductor device is described. A gate layer, a C-doped first protective layer and a hard mask layer are formed on a substrate and then patterned to form a first stack in a first area and a second stack in a second area. A second protective layer is formed on the sidewalls of the first and the second stacks. A blocking layer is formed in the first area and a first spacer formed on the sidewall of the second protective layers on the sidewall of the second stack in the second area. A semiconductor compound is formed in the substrate beside the first spacer. The blocking layer and the first spacer are removed. The hard mask layer in the first stack and the second stack is removed.

  • Patent number: 8709930
    Abstract: A semiconductor process is provided. The prior steps include: a first gate including a first cap layer and a second gate including a second cap layer are formed on a substrate. A hard mask layer is formed to cover the first gate and the second gate. The material of the hard mask layer is different from the material of the first cap layer and the second cap layer. The hard mask layer is removed entirely after a lithography process and an etching process are performed. The following steps include: a material is formed to entirely cover the first gate and the second gate. The material, the first gate and the second gate are etched back to make the first gate and the second gate have the same level and expose layers in both of them.

  • Patent number: 8278166
    Abstract: A method of manufacturing a CMOS device includes providing a substrate having a first region and a second region; forming a first gate structure and a second gate structure, each of the gate structures comprising a sacrificial layer and a hard mask layer; forming a patterned first protecting layer covering the first region and a first spacer on sidewalls of the second gate structure; performing an etching process to form first recesses in the substrate; performing a SEG process to form epitaxial silicon layers in each first recess; forming a patterned second protecting layer covering the second region; and performing a dry etching process with the patterned second protecting layer serving as an etching mask to etch back the patterned first protecting layer to form a second spacer on sidewalls of the first gate structure and to thin down the hard mask layer on the first gate structure.
