A formal object-oriented approach to the data structuring and data management of semiconductor wafer structure and device information is presented. The profile interchange format (PIF) is extended beyond a file format `intersite' version in order to enhance the storage and access of profile information, the communication of profile information between cooperating tools, and the integration and portability of technology CAD (computer-aided design) tools. An intertool PIF toolkit is a programmatic interface to profile information, consisting of a library of objects for the storage and manipulation of data by technology CAD tools. PIF/Gestalt is presented as a test implementation of the toolkit which provides C and Common Lisp language interfaces, implemented on a database for use in a CAD/CIM (computer integrated manufacturing) system for semiconductor process design and fabrication
