Abstract
As is well-known, semiconductor manufacturing is a technology-intensive operation carried out in an ultraclean dust-free environment. Such an environment can be best maintained by minimizing human intervention. Thus, the key for high yields and defect-free reliable microchips seems to be automation. Behind any automation project is an efficient and reliable computer network. In this paper, an overview of semiconductor manufacturing environment is presented so as to provide an insight into dataflow direction and requirements. Details of CIM/CAD/CAM requirements of semiconductor operations in terms of software and hardware are then elaborated upon. Next, a blueprint for a proposed company-wide network is detailed in terms of network topology transmission media, network access methods and communication protocols. The paper concludes with comments on specific benefits obtained from such a network, and possible future enhancements such as satellite links.
