Market-leading Microlithography Materials to Support Advanced Patterning

DuPont designs microlithography materials to improve existing microlithography processes as well as support advanced patterning processes. Our long history in lithography technology includes many industry-first enabling technology innovations. We lead the market in terms of our breadth of offerings, including ArF photoresists, KrF photoresists, i/g line photoresists, and organic bottom anti-reflective coating (BARC) materials.

By collaborating with you to understand your technical challenges, we develop materials solutions to meet them. The more advanced the process, the more critical it is to work in partnership to design specific materials.

DuPont is here to support you with your biggest (and smallest) lithography challenges! 

  • Microlithography, or photolithography, is an imaging technology that is critical to etch steps in semiconductor manufacturing. It is used to transfer circuitry patterns from a photomask to a silicon wafer, after which etch processes complete the pattern

  • Driven by ubiquitous high-performance, low-power computing needs, the semiconductor manufacturing industry continues to shrink feature sizes to make faster and smaller transistors with higher storage acapacity. This requires high-quality and high-performing lithography materials.

  • Photoresists


    DuPont’s robust, production-proven photoresist product line offers materials options that meet the requirements across generations of lithography processes.


    Positive tone ArF (193 nm) dry photoresists optimized for trench and line/space applications

    Positive tone 193 nm immersion resists with an excellent process window, CD uniformity and low defectivity

    Positive tone 193 nm implant resists with good profile through pitch and excellent substrate compatibility
  • Advanced Overcoats

    Advanced Overcoats

    Used in conjunction with photoresists, DuPont’s advanced overcoat materials are designed to prevent defects and improve the lithography process window, enabling finer feature patterns.

  • Anti-Reflectants & Functional Sublayers

    Anti-Reflectants & Functional Sublayers

    Anti-reflective coatings and sublayers boost the effectiveness of lithography by widening and improving the process and reflectivity windows.
