Silicon germanium pMOSFETs with channel lengths down to 0.4m have been fabricated on limited area silicon germanium virtual substrates. The devices have a 5nm thick Si0.3Ge0.7 active layer grown by MBE on top of relaxed Si0.7Ge0.3 virtual substrate. Virtual substrates were grown on top of 10μm square silicon pillars defined by etching trenches around their perimeter into the original silicon substrate. This limits the area of the growth zone, which in turn promotes the relaxation of the virtual substrate. Electrical measurements on 2μm long channel devices show that the maximum mobility in the strained SiGe devices is 211cm2V-1cm-1, compared to 104cm2V-1cm-1 for silicon reference devices. This increase in hole mobility increases the current drive of 0.4m devices measured at Vgt=-2V, Vds=-2.5V from 154μA/m to 192μA/μm.
