  • Publication number: 20100297818
    Abstract: In a method of making a semiconductor device, a first gate stack is formed on a substrate at a pFET region, which includes a first gate electrode material. The source/drain regions of the substrate are etched at the pFET region and the first gate electrode material of the first gate stack is etched at the pFET region. The etching is at least partially selective against etching oxide and/or nitride materials so that the nFET region is shielded by a nitride layer (and/or a first oxide layer) and so that the spacer structure of the pFET region at least partially remains. Source/drain recesses are formed and at least part of the first gate electrode material is removed by the etching to form a gate electrode recess at the pFET region. A SiGe material is epitaxially grown in the source/drain recesses and in the gate electrode recess at the pFET region. The SMT effect is achieved from the same nitride nFETs mask.

  • Publication number: 20100144112
    Abstract: Methods of forming air gaps between interconnects of integrated circuits and structures thereof are disclosed. A first insulating material is deposited over a workpiece, and a second insulating material having a sacrificial portion is deposited over the first insulating material. Conductive lines are formed in the first and second insulating layers. The second insulating material is treated to remove the sacrificial portion, and at least a portion of the first insulating material is removed, forming air gaps between the conductive lines. The second insulating material is impermeable as deposited and permeable after treating it to remove the sacrificial portion. A first region of the workpiece may be masked during the treatment, so that the second insulating material becomes permeable in a second region of the workpiece yet remains impermeable in the first region, thus allowing the formation of the air gaps in the second region, but not the first region.
