Analysis and Design of Blocking Characteristic of Reverse Conducting GCT
逆导型GCT阻断特性的分析与设计

The blocking characteristic of a conventional RC-GCT with pnp separation region is analyzed.A new RC-GCT structure with trench separation region is presented and the design considerations of its blocking characteristic are given.Based on the results,the structural model of RC-GCT with trench separation region is set up,and its blocking characteristic is simulated using a MEDICI simulator and compared with that of the asymmetry GCT without separation region and RC-GCT with pnp separation region.In addition,the optimum parameters of trench separation region are given by simulating characteristics of the RC-GCT for various trench structural parameters.The experiment results show that the design for the RC-GCT is reasonable.
