Lotte Energy Materials, AI Accelerator Ultra-Low Luminance Copper Foil Supply

Doosan Electronics BG Signs Supply Contract
Establishes Annual 1800t Mass Production System in Iksan

Lotte Energy Materials will be the first in the industry to supply next-generation AI (artificial intelligence) accelerator copper foil.

On the 17th, Lotte Energy Materials announced that starting this month, it will supply 'HVLP (Hyper Very Low Profile)' 4th generation copper foil for AI accelerators to Doosan Electronics BG, a copper-clad laminate (CCL) manufacturer.

Last month, Lotte Energy Materials established a system at its Iksan Plant 1 in Jeonbuk capable of mass-producing ultra-low gloss copper foil for AI accelerators with an annual capacity of 1800 tons. The existing general-purpose circuit foil line was converted into a dedicated high value-added HVLP4-grade line, and full-scale production has begun.

HVLP copper foil is classified from 1st to 3rd generation based on high-speed signal transmission efficiency, and currently, products used for AI accelerators are 3rd generation or below models. The ultra-low gloss copper foil supplied this time is a 4th generation product that minimizes signal loss due to its lower gloss while having similar tensile strength and elongation compared to the 3rd generation. It also features excellent adhesion strength due to the application of nano surface treatment technology.

Starting with the supply of 4th generation ultra-low gloss copper foil, Iksan Plant 1 plans to reorganize into a mass production system for high value-added products such as copper foil for networking and semiconductor packaging, as well as high-end battery foil.

Kim Yeon-seop, CEO of Lotte Energy Materials, stated, "Based on the DNA that succeeded in the first domestic localization of copper foil, we are the only company in the industry recognized to supply 4th generation copper foil for AI accelerators. We will solidify the value chain for networking such as AI accelerators and establish ourselves as a key supplier contributing to the growth of our customers."
