Semiconductor device and manufacturing method thereof |
| abstract |
A manufacturing method of a semiconductor device, comprising the following steps: providing a semiconductor substrate comprising a low-voltage device region and a high-voltage device region; forming first gate oxide layers in a non-gate region of the high-voltage device region and the low-voltage device region and a second gate oxide layer in a gate region of the high-voltage device region; the thickness of the second gate oxide layer is greater than the thickness of the first gate oxide layer; forming a first polysilicon gate and a first sidewall structure on the surface of the first gate oxide layer of the low-voltage device region and a second polysilicon gate and a second sidewall structure on the surface of the second gate oxide layer; the width of the second gate oxide layer is greater than the width of the second polysilicon gate; performing source drain ions injection to form a source drain extraction region; after depositing a metal silicide area block (SAB), performing a photolithographic etching on the metal SAB and forming metal silicide. The above manufacturing method of a semiconductor device simplifies process steps and reduces process cost. The present invention also relates to a semiconductor device. |
