On Monday, LG Chem announced that it will collaborate with Japan’s Noritake to develop a Silver Paste for bonding power semiconductor (SiC) chips and substrates in automotive applications.
Noritake, a Japanese firm with over 120 years of expertise in the precision ceramics field, supplies the semiconductor and automotive industries with products such as grinding wheels, electronic component materials, and firing furnaces.
With advancements in vehicle electrification and autonomous driving technologies, the demand for power semiconductors capable of handling high voltage and current has skyrocketed.
Traditional soldering methods have faced challenges as power semiconductor operating temperatures can reach up to 300 degrees Celsius (572 degrees Fahrenheit). This has created a pressing need for adhesives that maintain stability at high temperatures.
The silver paste jointly developed by the two companies is a high-performance adhesive containing silver (Ag) nanoparticles. It combines LG Chem’s particle design technology with Noritake’s particle dispersion technology to secure superior heat resistance and heat dissipation performance.
Conventional silver pastes are difficult to manage due to their need for refrigerated storage and short shelf lives. However, this new formulation can be stored at room temperature for long periods, which enhances transportation and storage efficiency. It also reduces waste by offering a longer usable life within customer manufacturing processes.
Both companies are committed to ongoing collaboration for the development of next-generation products.
Industry analysts project the automotive power semiconductor Silver Paste market to grow from approximately 300 billion KRW (approximately 221 million USD) in 2025 to 850 billion KRW (approximately 626 million USD) by 2030.
LG Chem Vice Chairman Shin Hak-cheol explained that based on their extensive technological expertise and material design capabilities, LG Chem has consistently delivered tailored solutions across various sectors, including automotive electronics. He stated that through their partnership with Noritake, they will strengthen their competitive edge in the global automotive adhesive market.
