A novel trench based stress modulation structure for strained 90nm-gate N MOSFET is demonstrated in this letter. The numerical simulation using SENTAURUS SPROCESS shows that, with this structure, the channel stress can be changed from compressive to tensile in a case of compressive CESL strained device. The relationships between the channel stress and the trenches' size are also investigated and it is deduced that the optimized trench depth and width can both be set to be 0.4um. With the trenches' size optimized, the trench based device can achieve an output current 24% higher than that of the N MOSFET without the trench based structure.
