Providing polymers with a lower metal content

Our Canadian site based in Saint-Jean-sur-Richelieu offers to the semi-conductor industry its expertise in the custom synthesis of photoresist polymers which are used to produce integrated circuits. These materials are produced with metal level at the low pbb and ppt level, positioning Seqens among the leading companies able to supply the semi-conductor industry. Thanks to recent investments in state-of-the-art technologies, our plant is now able to quantify lowest metal content in order to supply polymers with a lower metal content, enabling us to achieve the highest quality standards.

Ultra-trace metals analysis for microelectronics industry

For several industries such as pharmaceuticals, chemicals and cosmetics, metal content is often an important information for product development, quality control and regulatory compliance. For the microelectronics and semiconductors industry, which SEQENS Canada is evolving in, the nature of the metals and the level at which they are present can affect product’s quality. Consequently, the elimination of metallic impurities is critical in defects avoidance and requires extremely low metals for chemicals used in the microelectronics industry.

SEQENS Canada quality control laboratory has gained notable expertise in metal analysis of complex matrix such as polymers during the last 30 years. The team members are providing trace metals analysis parts per billion (ppb) of raw materials, in-process and final products to research and production services.

High-tech industrial equipment

To face the need for lower metal content in microelectronics industry, the laboratory recently acquired a range of highly selective technology instruments, improving the analysis capability and reaching ultra-low metals detection limit, as a few parts per trillion (ppt). Determining ultra-trace level of metals in samples can face several challenges, such as keeping the analysis noise at extremely low level and to minimize the metallic contribution to samples. To meet this goal, the quality control laboratory acquired state-of-the-art equipments to produce ultra-pure components, to better controlled samples handling and to avoid environment contamination which are the most challenging parameters for metal analysis.

Experienced staff, state-of-the-art instruments and controlled environment are key to measure ultra-trace metal content which is critical to meet constant evolution of the microelectronics market.
