采用场板和B+离子注入边缘终端技术的Ti/4H-SiC肖特基势垒二极管
Ti/4H-SiC Schottky Barrier Diodes with Field Plate and B+ Implantation Edge Termination Technology
摘要
Abstract
This paper describes the fabrication and electrical characteristics of Ti/4H-SiC Schottky barrier diodes(SBDs). The ideality factor n = 1.08 and effective Schottky barrier height (ψ)= 1.05eV of the SBDs were measured with the method of forward current density-voltage (J-V). A low reverse leakage current below 5.96 × 10-3A/cm2 at a bias voltage of - 1.1kV was obtained. By using B+ implantation, an amorphous layer as the edge termination was formed. We used the PECVD SiO2 as the field plate dielectric. The SBDs have an on-statk current density cm2.关键词
