Shaking Up Tradition with a Truly Fun Word (FOUP)

Beyond being one of the fun words in the semiconductor industry, the “FOUP,” front-opening-unified-pod, represented a radical change that has influenced the productivity of each fab and contributed to the capabilities our electronic devices today. At the inception of Moore’s Law in 1965, 30 mm (1.25”) diameter wafers were the standard. Leading up to the late 1990’s, seven generations of incremental increases would be introduced. At each point, manufacturing efficiencies and device performance opportunities existed to get “Moore” out of each wafer. Wafer storage and transport was primarily accomplished in open-air cassettes and pods, leaving wafers more susceptible to physical damage and contamination.

During the early days of the transition from 200 to 300 mm wafers, all aspects of wafer protection had escalated to critical concerns as chip complexity rose and fabs continued to seek process improvements. A small start-up proposed a new wafer handling approach and climbed the mountain of tasks with partners to introduce what is today the standard wafer transport solution around the world for 300 mm fabs (~120 and growing), the FOUP.

The story is best told by Gary Gallagher, senior director and “Father of the FOUP.” Much like other innovation stories, there were early adopters that proved instrumental in shaking up the traditional view from the top. There are also some twists along the way that make for another great story of how semiconductors continue to influence our lives because of the pioneers and partnerships that come with asking, “what if we ______?”.gary

How Does Quality by Design Affect Bulk Drug Cold Chain Manufacturing?

As a world-class supplier of advanced materials and process solutions for the semiconductor space, we understand the complexity and challenges of quality by design with respect to bulk drug cold chain manufacturing. Costly failures can be devastating and, in many cases, can be avoided by partnering with the correct single-use solutions provider to help optimize critical processes. When looking for solutions to protect your therapeutics during bulk drug cold chain, keep the following in mind:

Discussion of Freeze/Thaw Workflows

Meet Regulatory Requirements to Ensure Patient Safety Developing and validating a robust freeze/thaw process while meeting regulatory guidelines is a multifaceted challenge. The demand for cold chain processes and operations for biopharma products is increasing due to scaling of complex therapeutics, a challenging global supply chain, and growing shipping complexities. Ensuring compliance throughout the product journey is integral to mitigating risk for product loss and contamination.

Benchmarks Bridge the Semiconductor Yield and Reliability Performance Gap in the Automotive Domain

A major difference exists as more features from our smartphones are integrated, replicated, and expanded in our cars - reliability expectations. A smartphone is designed to work effectively for 3-5 years while cars expect 10-15 years with standard maintenance. Failure in our cars can create dangerous situations for drivers, passengers, and others on the roadway. Designing and manufacturing our cars to ensure the functional safety along with the performance expectations of our new digital transportation systems is challenging manufacturing models for carmakers.
