ICMTS 1999. Proceedings of 1999 International Conference on Microelectronic Test Structures (Cat. No.99CH36307).
This paper presents procedures and software tools for automatic generation of test masks, and mask and measurement databases, for SPICE model characterization. The process uses Cadence Pcells, and requires user specification only of a small amount of
