Contamination Control


Contamination control in a semiconductor fab is crucial for achieving acceptable device yields as feature size decreases and 3D structures proliferate. Advanced filtration and purification of air, bulk or specialty gas, and chemical throughout its process life cycle has become a critical aspect in reducing defects and enabling higher yields. IDMs (integrated device manufacturers) continue to tighten the acceptable specifications on parameters such as particles, metals, and organics in every chemical and gas they receive.

Particles, gels, metals, and airborne molecular contamination (AMC) all affect products, processes, and equipment in varying ways that lead to defective products. Liquid filters and purifiers provide a line of defense to prevent defect-causing contaminants from reaching the wafers and substrates. Whether for point of use or bulk delivery, in chamber or on wafer, in the cleanroom or on a tool, we have a long history of providing advanced liquid, gas, and air purification and filtration solutions to address your productivity and reliability requirements at any technology node.


The Fight for Purity in Chemical Manufacturing

The Fight for Purity in Chemical Manufacturing

The digital transformation we are all experiencing as consumers present new challenges to material makers, as well as opportunities. Contamination control remains one of the largest challenges as integrated circuit (IC) technology advances. Better contamination control can significantly improve yield, and a one percent yield improvement can mean up to $150 million per year in net profit.


Bridging the Filtration Gap Using an Empirical Model

 

Ashutosh Bhabhe, Senior Engineer, Liquid Filtration Applications, discusses how our empirical model, which combines fundamental chemical engineering with Entegris' knowledge, is helping bulk chemical suppliers choose the right advanced filter to maintain purity. And Siddarth Sampath, Applications Engineer, Liquid Purification and Metrology, explains using this model, which uses flow rate and retention attributes, to predict metal removal behavior in solvents to help provide optimized filtration throughout the supply chain.

Explore solutions to the gas purity challenges faced by semiconductor manufacturers.

Chasing the Perfect Pattern

Lithographers in semiconductor manufacturing are tasked with the challenge of creating circuit patterns that meet production yield, parametric performance, and long-term reliability requirements in the electronic devices our digital lives depend upon. To do this, predicting and controlling variables in the manufacturing systems, materials, and processes are critical.

The Lithographer's Toolkit

The lithographer’s toolkit provides a practical guide to reduce process variations that threaten your semiconductor fab performance.

High Purity Chemical Manufacturing

To enable the effective manufacturing of electronic devices for the Fourth Industrial Revolution, fabs (integrated circuit manufacturers) are challenged with producing denser and more complex chips with smaller line spacing and 3D features. The digital transformation we are all experiencing as consumers present new challenges to material makers, as well as opportunities. Contamination control remains one of the largest challenges as integrated circuit (IC) technology advances.

Enabling Advanced Lithography (EUV)

EUV reticle pods are highly specialized pieces of equipment that fulfill a critical role in EUV lithography. They must protect the reticle during use, storage, and transportation while not introducing additional contamination or damage.

The Rare Air of the Semiconductor Fab

Control of airborne molecular contaminants (AMC) enable manufacturers of integrated circuits (IC) to improve their production yield and further assure the integrity of electronic devices. Contaminant removal is achieved with AMC filters throughout the fab environment and at the tool locations.
