LG Chem Ltd., headquartered in Seoul, South Korea, has officially commenced the mass production and commercial supply of semiconductor stripper materials to Amkor Technology Inc., a leading outsourced semiconductor assembly and test (OSAT) provider based in the United States. This milestone represents LG Chem's first commercial entry into the semiconductor stripper market and supports the company's broader strategy of expanding its presence in the high-value semiconductor materials sector.
Semiconductor strippers are essential specialty chemicals used during chip manufacturing to remove photoresist (PR) layers and residual contaminants left on semiconductor wafers after circuit patterning. As semiconductor devices continue to become more compact and technologically advanced, efficient residue removal has become increasingly critical for maintaining production yields, ensuring device reliability, and achieving high manufacturing quality. Consequently, stripper materials have become an indispensable component of advanced semiconductor fabrication processes.
LG Chem leveraged the technological capabilities and customer support expertise it developed through its display stripper business to enter this new market segment. The company successfully completed Amkor Technology's stringent product qualification process, demonstrating the competitiveness and reliability of its newly developed semiconductor stripper solution. Securing approval from one of the world's largest semiconductor packaging and testing companies highlights LG Chem's ability to meet demanding industry standards.
The semiconductor stripper supplied to Amkor has been specifically tailored for the company's latest production line. According to LG Chem, the product reduces the time required to eliminate photoresist and process residues by nearly 50% compared with conventional stripper materials. This significant improvement is expected to enhance manufacturing efficiency, reduce processing costs, and support higher production throughput.
Market demand for advanced semiconductor process materials continues to strengthen, fueled by rapid investments in artificial intelligence (AI), expanding high-bandwidth memory (HBM) production, and the increasing adoption of advanced semiconductor packaging technologies. These industry trends are creating new opportunities for suppliers capable of delivering specialized, high-performance materials.
Kim Dong Choon, CEO of LG Chem, stated that the partnership with Amkor Technology reinforces the company's ability to provide customized material solutions optimized for customers' manufacturing processes while strengthening its competitiveness in the semiconductor materials industry.
Earlier this year, LG Chem announced plans to more than double the size of its electronics materials business. As part of this strategy, the company is expanding its portfolio of semiconductor packaging materials, including copper-clad laminates (CCL), die attach films (DAF), and photo-imageable dielectric (PID), while accelerating investments in premium electronic materials that support next-generation semiconductor manufacturing.
Impact on Product and Chemical Commodity Prices
LG Chem's entry into the semiconductor stripper market is expected to strengthen the supply of high-performance semiconductor process chemicals, improving manufacturing efficiency and supporting advanced chip packaging production. Rising adoption of customized stripper materials may increase demand for specialty solvents, amines, surfactants, glycol ethers, and other high-purity electronic chemicals used in semiconductor fabrication. For chemical commodities tracked by ChemAnalyst, the immediate price impact is likely to remain limited due to adequate global supply. However, sustained growth in AI, HBM, and advanced semiconductor packaging could gradually tighten demand for electronic-grade specialty chemicals, supporting firm-to-moderately higher prices over the medium to long term.
