双步退火恢复4 SiC DIMOSFET离子注入缺陷
Double Step Annealing for the Recovering of Ion Implantation Defectiveness in 4H-SiC DIMOSFET
摘要:
热退火对于修复DIMOSFET(双注入MOSFET)器件离子注入区的缺陷起着至关重要的作用。在这项工作中,我们已经研究了这种器件的体(Al注入)和源(P注入)区的双步骤退火的效果。我们发现,高温退火(1750°C,1小时),然后是低温退火(1500°C,4小时)是强制性的,以在器件的n型区和p型区中实现低缺陷浓度和良好的晶体质量。
英文摘要:
Thermal annealing plays a crucial role for healing the defectiveness in the ion implanted regions of DIMOSFETs (Double Implanted MOSFETs) devices. In this work, we have studied the effect of a double step annealing on the body (Al implanted) and the source (P implanted) regions of such devices. We found that a high temperature annealing (1750°C, 1h) followed by a lower temperature one (1500°C, 4h) is mandatory to achieve low defects concentration and good crystal quality in both the n- and p- type zones of the device.
