Working with Photoresist

Advanced Photoresists:


Drawing on the broad expertise our company has accumulated over many years as a diversified chemical company, our company continues to expand our line of SUMIRESIST® positive-type photoresists. As one of the leading photoresist suppliers in the world, our product portfolio covers a wide range of technologies and applications. In anticipation of ever growing and diversifying customer needs, our company continuously increase and focus our development efforts on more advanced resist platforms, including those for next generation lithography technologies.

  • i-line: PFI / PFM / PXi / NX Series photoresists for all critical and non-critical applications.
    • We also offer chemically amplified i-line resist (PXi / NX series). Please see slide 3 of ‘i-line/KrF/ArF’ information sheet.
  • KrF: PEK Series photoresists for all critical and non-critical applications.
  • ArF: PAR Series photoresists (both dry and immersion applications) for your most demanding applications.
  • We are developing multiple advanced patterning techniques with out partners to meet the continuing lithography roadmap requirements
