In this thesis, we focus our attention on the measurement of the quasi-static MOSFET capacitance and Levelized incomplete LU method. Direct LU decomposition is not suitable for large-scale device simulation, because a lot of fill-ins will be generated during LU decomposition. Levelized incomplete LU method provides a good way to improve traditional LU decomposition. The structure of the metal gate and the method of the interleaving variable permutation are used. The use of the metal gate can save some rectangular grids which are used to describe the poly gate terminal. The use of the interleaving method reduces the number of fill-ins. In the meantime, the main focus of this thesis is on the measurement of gate to substrate, gate to source, and gate to drain capacitances of MOSFET. These measurements are implemented by charge method, sinusoidal method, and ramp method. The results of C-V characteristics are compared. Finally, we try to reduce memory space by changing the data type, but it is quite difficult. Therefore, we proposed decoupled method to reduce the number of nonzero entries. |
