On July 5, LG Chem announced it will begin mass production of semiconductor strippers for Amkor, a global leader in semiconductor packaging and testing services. Amkor serves major semiconductor companies in the backend sector.
Strippers are essential materials used to remove photoresist (PR) and residues left on substrates after semiconductor circuit formation. As circuit miniaturization progresses, the performance of residue removal directly impacts product yield and reliability, making stripper technology a critical factor in semiconductor quality.
Leveraging its expertise and customer experience gained from the display stripper business, LG Chem has entered the semiconductor stripper market. The company has confirmed its competitiveness by passing the stringent technical validations of global OSAT companies with its first semiconductor product.
The product being supplied to Amkor is a customized stripper optimized for the company's new line, significantly reducing the time required to strip photoresist and residues by 50%, thereby enhancing process efficiency.
With recent increases in AI investments and demand for high-bandwidth memory (HBM), investments in advanced packaging are rising, further highlighting the importance of high-performance process materials.
Kim Dong-chun, CEO of LG Chem, stated, "Through our collaboration with Amkor, a world-class backend company, we will further strengthen our competitive edge in customized materials optimized for customer processes."
Additionally, LG Chem has reduced the supply price of basic petrochemical products, such as ethylene and propylene, by 100,000 to 200,000 won per ton, utilizing government subsidies to support small and medium-sized customers and enhance cooperative relations.
