| Research Abstract |
The dopant distributions and high-k gate dielectrics in metal-oxide-semiconductor field effect transistor structure were analyzed by three dimensional atom probe tomography. The remarkable difference of dopant distribution between n-MOSFET and p-MOSFET was clearly observed. Futher investigations are needed for the high-k gate dielectrics structures obtained by three dimensional atom probe tomography.
