DuPont and Kempur Microelectronics Announce Collaboration

Collaboration Will Enhance Access to Advanced Microlithography Materials in China

SHANGHAI, CHINA, Nov. 8, 2021 – DuPont Electronics & Industrial and Kempur Microelectronics, Inc. today announced a collaboration program to supply materials for microlithography in China. The collaboration will leverage the strengths of both DuPont and Kempur to address industry needs for advanced photoresists and other lithographic materials.

As reported in SEMI’s quarterly World Fab Forecast Report, chipmakers in China have announced eight new fabs starting construction by 2022. These new fabs will accelerate the country’s domestic semiconductor industry and drive increased needs for materials and local support in the years to come. DuPont and Kempur’s collaboration will enable Kempur to quickly supply a wide range of lithographic materials to support customer growth.

“Kempur is a strong partner for DuPont in China, with a talented team, valued customer relationships and a reputation for quality and customer intimacy that aligns with our own business values,” said George Barclay, Global Business Director, Litho Technologies. “We’re pleased to be able to support the local market through this new collaboration and we look forward to new opportunities opening as a result.”

“China's photoresist market is in a period of rapid development, and Kempur Microelectronics needs a world-class partner like DuPont to effectively keep pace," said Cindy Chen, CEO of Kempur Microelectronics. "Compared with DuPont's long history, Kempur is still a very young company. We hope to work with DuPont to continuously innovate, focus on challenges and promote the development of the industry."

DuPont is a leading global supplier in materials for semiconductor fabrication, with a diverse array of established products for lithography at multiple wavelengths, including 193nm (ArF), 248nm (KrF) and i/g-line photoresists, as well as spin-on carbon (SOC), antireflective coating materials (BARCs), advanced overcoats and ancillaries.

Kempur was established in 2004 and today is the biggest photoresist manufacturer in China. Kempur’s portfolio includes photoresists and other supporting materials for integrated circuit fabrication, as well as resists used in the fabrication of light-emitting diodes (LED) and other applications.

DuPont and Kempur representatives commemorated this collaboration at an event on Saturday, November 6, during the China International Import Expo. Interested parties should contact their Kempur account manager to learn more.
