TECHNOLOGIES AND INTEGRATION PROCESSES
Any manufacturable device has four essential characteristics:
Superior and pre-specified performance, with reproducibility, uniformity, and reliability;
High yield to acceptable tolerance; Simulations exist for both reverse
engineering during development and right-first-time design;
Proven adequate in-service lifetime.
