The semiconductor industry is constantly striving to improve the performance, reliability, and cost of electronic devices. The growing complexity in the design process of microelectronics coupled with the requirement of significant investment in research and development means that there is hardly any entity in the industry that is capable of acquiring the state-of-the-art technologies for all facets of the development process across myriad niche device technologies. Therefore, for economic and practical reasons, the modern electronic supply chain relies on several different vendors that specialize in a specific area of the design and fabrication process.
