Abstract

See full text

A mask defect printability simulation server provides simulations, one-dimensional analysis, and reports to multiple clients over a wide area network, such as the Internet. This network-based simulation server allows a client to leverage a core of highly-trained engineers. Additionally, the network-based simulation server can be easily supported since only a single source for the tools associated with the simulation server is necessary for multiple clients. A client can access the simulation server using a standard personal computer having a browser, thereby eliminating the need for client to maintain an expensive database for the server. Finally, in the network-based simulation server, multiple users can view the same mask defect image and provide real-time comments to each other as simulation and analysis are performed on the defect image, thereby encouraging problem solving and decision-making dialogue among the users.
