Interoperability of physical simulation tools is often cumbersome due
to dif- ferences in domain representation. The Technology Computer
Aided Design (TCAD) community (1) has realized this problem and is
working on providing an object-oriented interface for representing and
manipulating the state of a semiconductor wafer during process and
device simulation, the Semiconduc- tor Wafer Representation (SWR) [1,
2, 3]. We describe an implementation of components of a 3D SWR
designed to support the needs of many TCAD simulators. A set of
classes provide support for solid modeling operations, mesh refinement
operations, and data interchange. A layered memory subsystem allows
either uniprocess or client/server operation. Run-time type
identification provides dynamic extensibility of data types.
