A utility-based integrated system for process simulation

Abstract

An integrated process simulation system which uses functional utilities to integrate disparate 2-D simulation tools is described. The software utilities provide mechanisms for simulator input generation and user interaction, for mapping between different cross-section formats, and for output visualization. The specific utilities are described. With this approach, several process simulators for lithography, etching, deposition, and thermal processing have been integrated into a unified system, SIMPL-IPX (simulation of profiles from the layout-integrated process simulation environment with X-Windows). Simulation examples for metal l planarization, bipolar technology with a polysilicon , collector 5 plug, and advanced lithography are presented to demonstrated 7 the usefulness of this approach to technology CAD tool 8 integration. Methods for improved data management using 9 a CAD framework are described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
