As electronic systems rapidly evolve with many new features and functions, chipmakers continue to look for ways to innovate and gain competitive high ground. This has led to a huge increase in the complexity of designing products, raising the level of systems integration to new heights. Manufacturers of semiconductor devices face increasingly difficult challenges. Unlike other process industries, semiconductor manufacturing follows a very complex process flow, rather than a classic serial process flow, wherein assemblies are built on prior steps. Most often, semiconductor manufacturing process steps begin serially and then loop back on themselves to remove prior oxide, metal, and/or polyimide levels and gate structures.

Magnifying the technical challenge of device fabrication is the need for a manufacturing automation strategy able to migrate to next-generation technologies and incorporate stateof the-art equipment, without sacrificing the huge investments already made in developing and implementing manufacturing applications.

To deal with the complexity, both midsize and large companies realize that a deep understanding of engineering and technology is not enough. When the objectives are to speed time to market for new offerings, reduce development expenses, and improve revenues by integrating increasingly sophisticated technologies will work.

As global competition increases, identifying, updating, and managing an automation strategy for present needs must also include consideration of future processes and manufacturing technologies. Therefore, whatever equipment, process, and manufacturing control strategy is developed, future expandability and flexibility are critical to its success. Key to the successful integration of any advanced semiconductor and electronic process equipment strategy are

  • The design and execution of MESs
  • Advanced control and process monitoring systems that provide flexibility
  • Software tools that enable functional expandability, connectivity, interoperability, and multiplatform portability in a distributed multivendor environment

Recent trends toward an open system architecture address those key needs for both the semiconductor manufacturer and the equipment manufacturer.

Open system architecture is defined as a system’s ability to provide a software environment that allows not only an external ability to interface and pass/share data with remote devices and process controllers, but also an inherent ability to empower the user to enhance, add, or replace any internal function, configuration tool, or editor.

A truly open architecture puts the user on equal ground with the software vendor’s internal development group. It ensures modularity, interoperability across dissimilar operating systems, and the ability to incorporate new standards and off-the-shelf software tools, while remaining at an application layer transparent to the user. An additional benefit: open system architecture minimizes the time required to develop an application and replicate it across different operating systems.

Open system architecture should be based on industry standards. The relationship between the architecture and the standards should be interdependence, not a rigid bond. Standards set the guidelines for achieving interconnectivity in a modular system.

The Semiconductor  Framework describes a base software infrastructure that creates a common environment for integrating applications and sharing information in a given domain. Another benefit is decreased time to bring a fabrication facility into full operation, because of faster equipment and factory integration.

New initiatives in the semiconductor industry are focused on applying Web-based solutions to functions typically assigned to MESs, which in turn have the potential to facilitate the adoption of the New Framework.
