    摘要: The formation of shallow trench isolations in a strained silicon MOSFET includes performing ion implantation in the strained silicon layer in the regions to be etched to form the trenches of the shallow trench isolations. The dosage of the implanted ions and the energy of implantation are chosen so as to damage the crystal lattice of the strained silicon throughout the thickness of the strained silicon layer in the shallow trench isolation regions to such a degree that the etch rate of the strained silicon in those regions is increased to approximately the same as or greater than the etch rate of the underlying undamaged silicon germanium. Subsequent etching yields trenches with significantly reduced or eliminated undercutting of the silicon germanium relative to the strained silicon. This in turn substantially prevents the formation of fully depleted silicon on insulator regions under the ends of the gate, thus improving the MOSFET leakage current.

    摘要: The formation of shallow trench isolations in a strained silicon MOSFET includes implantation of a dopant into overhang portions of the strained silicon layer and silicon germanium layer at the edges of trenches in which shallow trench isolations are to be formed. The conductivity type of the dopant is chosen to be opposite the conductivity type of the source and drain dopants. The implanted dopant increases the threshold voltage Vt beneath the ends of the gate in overhang portions of the strained silicon layer so that it is approximately equal to or greater than that of the remainder of the MOSFET. The resulting strained silicon MOSFET exhibits reduced leakage current beneath the ends of the gate.
