Amkor is a global leader in backend semiconductor services, providing packaging and testing solutions to major semiconductor companies.

A stripper is a key process material used to remove photoresist (PR) and residues remaining on the substrate after forming semiconductor circuits. As circuit miniaturization advances, the performance of residue removal directly impacts product yield and reliability, making the technological capability of the stripper a critical factor in determining semiconductor quality.

Based on its accumulated technological expertise and customer response experience from its display stripper business, LG Chem has entered the semiconductor stripper market.

The product LG Chem is supplying this time is a customized stripper optimized for Amkor's new production lines. It reduces the time required to strip photoresist and residues by 50% compared to previous solutions, significantly improving process efficiency.

With the recent expansion of AI investment and growing demand for high-bandwidth memory (HBM), investments in advanced packaging are increasing, further raising the importance of high-performance process materials.

Dongchun Kim, CEO of LG Chem, stated, "Through our collaboration with Amkor, a world-class backend company, we will further strengthen our competitiveness in providing customized materials optimized for our customers' processes."
