# DuPont's Qnity Expands SK Hynix Partnership As It Prepares To Go Solo

> DuPont's Qnity has expanded its partnership with SK hynix to supply advanced CMP polishing pads for semiconductor production. This long-term agreement, signed during SEMICON West, aims to enhance CMP performance in memory device fabrication. As Qnity prepares for its separation from DuPont on November 1, 2025, it will focus on the semiconductor market, leveraging its expertise in CMP technology. DuPont shares rose by 0.28% to $78.75 following the announcement.

DuPont de Nemours, Inc. (NYSE:DD) said its electronics business, **Qnity**, has partnered with South Korea’s **SK hynix** to supply advanced chemical mechanical planarization (CMP) polishing pads used in semiconductor production.

The strategic long-term agreement supports SK Hynix’s ongoing need for advanced CMP pads, which are used for its next-generation semiconductor manufacturing and mass production processes.

“This agreement reflects our shared commitment to enabling advancements in the semiconductor and electronics industries through collaboration,” said **Sanjay Kotha**, Global Business Director of CMP Technologies at Qnity. He added that the company is proud to help advance SK hynix’s innovation roadmap through its CMP materials and engineering expertise.

## Qnity Separation

The new agreement comes as Qnity prepares for its planned separation from DuPont, expected on November 1, 2025.

The move will allow Qnity to focus exclusively on the semiconductor and electronics markets while DuPont continues its broader materials innovation strategy.

**Price Action:** DD shares were trading higher by 0.28% to $78.75 at last check Thursday.
