Abstract

Complementary Metal-Oxide-Semiconductor (CMOS) devices and circuits with minimum feature sizes of about 1 μm were fabricated in 0.5-μm-thick epitaxial Silicon-On-Sapphire (SOS) films. The films were modified by ion implantation and subsequent solid phase recrystallization processes which reduced the total microtwin concentrations in the Si layers by more than a hundredfold, while increasing electron and hole channel mobilities between 40 to 50%. Leakage currents were reduced by over 2 orders of magnitude, while drive currents and subthreshold slopes showed significant improvements over as–grown SOS films. Propagation delays of less than 80 psec were obtained for CMOS/SOS inverters with Leff = 0.6 μm.
