Abstract :
The mechanical stress induced by shallow trench isolation (STI) has been characterized by using complementary techniques: 1) TCAD simulation compared with UV-muRaman data to determine the lattice misfit strain; 2) full band Monte Carlo simulation and electrical measurements to study the impact on the transport properties. For the first time, an iterative methodology emphasising the synergy among these techniques is presented. The excellent agreement with our electrical data demonstrated that our methodology is a powerful and useful tool to predict the performance of devices with a controlled stress
