R&D

Making our best effort to secure
a position
as a leader in the future
semiconductor market

NC Chem is focusing on domestication of core materials and early-stage development of
next-generation materials. We are pursuing innovative research by establishing independent
development processes.

Research
Area

Based on a variety of analysis technologies such as organic and polymer synthesis
technology accumulated over time, NC Chem is developing core polymer materials
used in various electronic industries, such as semiconductors.

Furthermore, for quality control of developed and mass-produced products,
we manage with equipment capable of measuring up to parts per billion (PPB) unit.

Polymer Material

Key raw materials for semiconductor
photoresists,
such as KrF polymer,
ArF polymer, EUV polymer, etc.

Photosensitizer Material

KrF, ArF and EUV PAG, etc.
for semiconductor

Core
Competency

We have differentiated technological capabilities to ensure product innovation and continuous
competitive advantage.
