Two types of 5μm thick hybrid orientation structure wafers,which were integrated by(110)or(100) orientation silicon wafers as the substrate,have been investigated for 15-40 V voltage ICs and MEMS sensor applications.They have been obtained mainly by SOI wafer bonding and a non-selective epitaxy technique,and have been presented in China for the first time.The thickness of BOX SiO_2 buried in wafer is 220 nm.It has been found that the quality of hybrid orientation structure with(100)wafer substrate is better than that with(110)wafer substrate by“Sirtl defect etching of HOSW”.
