[SDI Today] Semiconductor Process Materials Powering the AI Era
"To realize ultra-fine semiconductor patterns at nanometer-scale, the role of semiconductor process materials will become increasingly important." On August 12, at the ‘NGL 2025’ conference held at the Suwon Convention Center, Chung-bong Lee (Ethan CB Lee), Vice President of SAMSUNG SDI’s Electronic Materials Business, gave a presentation on semiconductor process materials that are gaining attention in the AI era.
[SDI Focus] Separators: The Hidden Hero behind Battery Safety
In lithium-ion batteries, the separator is a material that prevents physical contact between the anode and cathode while simultaneously allowing lithium ions to move freely between them. Although these functions may seem contradictory at first glance, various technologies are applied to the separator to enable it to perform both roles effectively.
The separator is made from polymer materials such as PP and PE*, which are commonly found in everyday items like plastic bags and containers. These base materials are mixed with additives and processed into a film. The separator is then manufactured through stretching and extraction processes. Stronger stretching increases the separator’s stren
