文摘A high-performance PMOSFET based on silicon material of hybrid orientation is obtained.Hybrid orientation wafers,integrated by（100） and（110） crystal orientation,are fabricated using silicon-silicon bonding, chemical mechanical polishing,etching silicon and non-selective expitaxy.A PMOSFET with W/L = 50μm/8μm is also processed,and the measured results show that the drain-source current and peak mobility of the PMOSFET are enhanced by up to 50.7%and 150%at V_（gs） =-15 V and V_（ds） =-0.5 V,respectively.The mobility values are higher than that reported in the literature.
