Applications of Two- and Three-Dimensional General Topography Simulator in Semiconductor Manufacturing Processes

چکیده
We present applications of the twoand three-dimensional general purpose topography simulator ELSA (Enhanced Level Set Applications) for semiconductor manufacturing processes. The first process considered is the deposition of silicon dioxide from TEOS for power MOSFETs. For backend processes in addition to a TEOS process, the deposition of silicon nitride into interconnect lines, where two and threedimensional void characteristics play an important role for determining timing delays and cracking effects, is necessary and thus is simulated.

Progress in today 's semiconductor industry has been mainly achieved by decreasing the minimal feature size and increasing the complexity and thus the nonplanarity of the devices. Therefore lithography tools have to provide high resolution with a reasonable large depth of focus. A well-established method to achieve both requirements are off-axis illumination techniques. As topography effects su...

For the prediction of the device performance of FinFET structures three-dimensional device simulation is inevitable. Due to the strong quantum mechanical confinement in the channel, quantum correction models need to be applied. Two of these models, where one is based on the correction of the densityof-states in a pre-processing step and the other calculates a correction for the band edge energy...
