| 20110230042 | METHOD FOR IMPROVING THERMAL STABILITY OF METAL GATE - The present disclosure provides a method of fabricating a semiconductor device that includes providing a semiconductor substrate, forming a gate structure on the substrate, the gate structure including a dummy gate, removing the dummy gate from the gate structure thereby forming a trench, forming a work function metal layer partially filling the trench, forming a fill metal layer filling a remainder of the trench, performing a chemical mechanical polishing (CMP) to remove portions of the metal layers outside the trench, and implanting Si, C, or Ge into a remaining portion of the fill metal layer. | 09-22-2011 |
| 20110227161 | METHOD OF FABRICATING HYBRID IMPACT-IONIZATION SEMICONDUCTOR DEVICE - The present disclosure provides a semiconductor device which includes a semiconductor substrate, a first gate structure disposed over the substrate, the first gate structure including a first gate electrode of a first conductivity type, a second gate structure disposed over the substrate and proximate the first gate structure, the second gate structure including a second gate electrode of a second conductivity type different from the first conductivity type, a first doped region of the first conductivity type disposed in the substrate, the first doped region including a first lightly doped region aligned with a side of the first gate structure, and a second doped region of the second conductivity type disposed in the substrate, the second doped region including a second lightly doped region aligned with a side of the second gate structure. | 09-22-2011 |
