LG Chem Starts Volume Supply of Packaging Stripper Material to Amkor

LG Chem said it has started supplying semiconductor stripper material to Amkor Technology for use in a new production line, marking the company’s first commercial deployment of this product in semiconductor manufacturing. The material is used to remove photoresist and residue after circuit patterning, and LG Chem says the customized version for Amkor cuts removal time by about 50% versus existing products after passing qualification for volume production. For RamTrend, the main significance is indirect: the deal adds capacity and competition in advanced packaging materials at a time when AI investment and HBM demand are pushing more activity into high-end packaging flows. That does not directly change DRAM or NAND pricing today, but it supports the broader supply chain needed for memory products that depend on advanced packaging and substrate-level process control.
