Fabrication of self-aligned drain and source on insulator MOSFET with dielectric pocket by local SIMOX technology

In this work, a method to fabricate SA-DSOI MOSFET with dielectric pocket has been presented. Dielectric pocket and BOX are realized by local SIMOX technology. This novel structure results in good SCE and SHE suppression and higher speed performance, which is very important in nanoscale device design. With this novel self-aligned process, DSOI MOSFET can be scaled down to nano-scale and becomes a promising device.
