Abstract: | A new SCD-LDD (Surface Counter Doped LDD) structure is proposed. This structure introduces an additional oblique BF2 implant after nLDD implant, which counter-dopes the nLDD surface concentration near the gate edge. As a result, the lateral electric fields beneath the gate were reduced and the saturation drain current was conducted downward away from the maximum electric fields, resulting in a substantial enhancement of hot carrier reliability due to suppression of hot carrier generation and injection with this structure. |
