Scientific and Engineering Semiconductor Device Simulation Tools as a WindowsApplication

摘要

A bottleneck associated with numerical simulations of quantum feature sizesemiconductor devices, has been the absence of a menu driven program that does not require user knowledge of the solution algorithm for the device equations. Under this SBIR study SRA transferred quantum transport algorithms, originally developed for supercomputer simulations to a PC environment. This resulted in (1) program execution via menu based MMicrosoft Windows-type interface, (2) user-defined parameters (dimension, doping, material property, voltage, etc.), (3) an intuitive user interface, and (4) acceptable execution and throughput times when compared to workstations and supercomputers. Under the Phase II study SRA configured three numerically robust software programs (plus operating manuals) for PC-Windows operation. These codes are ready for sale. The Fortran based simulation algorithms are: (1) S RA's algorithm for solving the quantum Liouville equation in the coordinate representation; (2) SRA's one dimensional quantum hydrodynamic algorithm; (3) SRA's two dimensional quantum hydrodynamic algorithm configured for HEMT simulations. The first two algorithms include time dependence. The algorithms can provide device parameters for coupling to standard commercially available circuit packages.
