Science that is transforming lives and enabling the future
To meet increasing sensitivity to contaminants in integrated circuit (IC) manufacturing, semiconductor fabs have begun looking to their chemical suppliers to adopt new contamination control standards that improve quality and assist in reducing wafer defects. Each material has several touch points along the chemical manufacturing, storage, transport, and delivery journey that could add or generate contaminants. Semiconductor fabs seek assurance from their materials suppliers that they will minimize opportunities for contaminants to end up on a wafer (Figure 1).
The automotive supply chain is transforming with the development of autonomous vehicles. The rise of electronic systems leads designers and manufacturers to seek collaboration partnerships. Antoine Amade, senior director EMEA/NA sales, was recently interviewed by SEMI to discuss the zero-defect challenges facing semiconductor fabs and the expansion of the GAAC (Global Automotive Advisory Council).
Ensuring Purity and Safety Purity requirements continue to tighten as the semiconductor manufacturers continue to pursue advanced technology nodes. Of all the industries that rely on a consistent supply of both raw and specialty chemical, the semiconductor industry sets the highest bar.
During the semiconductor manufacturing process, contamination can be introduced from the air, equipment, cleanroom personnel, process water, process chemicals, and process gases.1 Careful identification of the contaminant source is required to best identify mitigation strategies that utilize filtration. Installing a filter can reduce defectivity, but this mitigation strategy will not indefinitely protect a gas stream from contamination.
The desire for ever more computing power in a smaller footprint requires transistors that perform faster while consuming less power. However, new materials and architectures developed with these goals in mind are not easy to transfer from research and development to full-scale, high-volume production.
Dewetting and non-dewetting are not common terms used every day, yet are vital to the functionality of liquid filters.
Entegris Highlights 2019 2019 was a year of exciting change and significant accomplishments for Entegris including strategic acquisitions, supplier awards, footprint expansions and technology center openings, sustained Five+ Sigma quality levels, hundreds of issued technology patents, and so much more!
Wetting the membrane is an important first step in preparing your filter. Wetting the membrane pores eliminates dry pathways where contaminants, like particles, gels, or bubbles could pass through, resulting in high defect levels in your process. Polymer membranes are natively hydrophobic or hydrophilic.
