LG Chem has entered the semiconductor stripper market.

 

The company has secured its first mass production and supply agreement with global outsourced semiconductor assembly and test (OSAT) leader Amkor Technology as it pushes to expand its high-value semiconductor materials business.

 

The deal marks a significant milestone for LG Chem, which has leveraged expertise from its display stripper business to break into the semiconductor sector. The company said it successfully cleared Amkor's stringent qualification process with its inaugural semiconductor stripper product.

 

Semiconductor strippers are essential process chemicals used to remove photoresist and residue after circuit patterning. As chip geometries continue to shrink, efficient residue removal has become increasingly critical to manufacturing yields, product reliability and overall semiconductor quality.

 

LG Chem said the stripper supplied to Amkor was customized for the company's new production line and cuts the time needed to remove photoresist and process residue by about 50% compared with existing products, boosting manufacturing efficiency for advanced semiconductor packaging.

 

The launch comes as demand for advanced semiconductor materials accelerates, fueled by growing investment in artificial intelligence (AI) and rising demand for high-bandwidth memory (HBM), both of which are driving next-generation semiconductor packaging technologies.

 

Kim Dong Choon, CEO of LG Chem, said, “Through our collaboration with Amkor, a world-class semiconductor packaging and testing company, we will further strengthen our competitiveness in delivering customized materials optimized for customers’ manufacturing processes.”
