CONTACT ETCHING TO INCREASE BREAKDOWN VOLTAGE OF GRADED NMOSTs | ||||||
Author(s) | Nebojsa D. Jankovic | |||||
Abstract | The influence of silicon contacts etch in freon plasma on short channel breakdown characteristics of Fully Graded (FG) NMOSTs has been examined. An experimental FG NMOSTs, featuring Leff=3.7μm, 8Vds=46V and BVsus=35V, has been fabricated and subjected to contacts etch process . It appears that carefully optimized plasma etching of source-drain contacts can completely eliminates bipolar-like breakdown sustaining voltage (BVsus) without affecting other FG NMOST's electrical parameters. | |||||
