LG Chem Enters Semiconductor Stripper Market with First Commercial Supply Deal for Amkor Technology
The South Korean chemicals company has started mass production of customised semiconductor strippers for Amkor Technology, strengthening its semiconductor materials portfolio amid rising demand driven by AI and HBM chip manufacturing.
LG Chem has entered the semiconductor stripper market with its first commercial supply agreement, securing Amkor Technology as its inaugural customer for the specialised process material.
The South Korean chemicals company announced that it has begun mass production of customised semiconductor strippers designed specifically for Amkor's latest manufacturing equipment. According to LG Chem, the new formulation reduces residue removal time by approximately 50% compared with conventional products, helping to improve process efficiency.
Semiconductor strippers are used to remove hardened photoresist and organic residues following etching and ion implantation processes. As chip manufacturing continues to move towards finer process nodes, these materials play an increasingly important role in maintaining production yields and ensuring device reliability.
LG Chem said it leveraged the expertise and customer support capabilities it developed in the display stripper business to expand into semiconductor process materials. The company added that completing the stringent qualification process required by a leading global outsourced semiconductor assembly and test (OSAT) provider demonstrates the competitiveness of its technology.
The agreement forms part of LG Chem's broader strategy to strengthen its portfolio of advanced electronic materials as demand for AI computing and high-bandwidth memory (HBM) continues to grow. Earlier this year, the company announced plans to more than double the size of its electronic materials business while expanding its semiconductor packaging materials portfolio, including copper clad laminates (CCL), die attach films (DAF) and photo-imageable dielectrics (PID). It also intends to invest KRW15 trillion in research and development by 2035.
Kim Dong-chun, President of LG Chem, said the company would continue to enhance its competitiveness by working closely with Amkor to develop customised materials tailored to customers' manufacturing processes.
