Hanul Semiconductor is experiencing a surge in stock prices following the announcement of its development of an AI-based inspection system for multilayer ceramic capacitors (MLCCs).

According to the Korea Exchange, as of 9:38 a.m. on July 20, Hanul Semiconductor's shares rose by 3,920 won (29.97%) to 17,000 won compared to the previous trading day. The stock opened higher and gained momentum throughout the morning, reaching the daily limit.

The company announced that it has developed a comprehensive inspection system for MLCCs that combines AI vision technology with predictive capabilities for production line anomalies. It is currently in discussions with global clients for mass production supply.

MLCCs are essential components that regulate the stable flow of current in electronic product circuits, utilized in smartphones, home appliances, AI servers, electric vehicles, and autonomous cars. As the related industries advance, the importance of inspection technologies to ensure product stability and reliability is increasing.

Unlike traditional sampling inspection methods, this new system focuses on inspecting the entire production output. The company stated that it has enhanced inspection accuracy and productivity by integrating high-speed ultrasonic inspection technology with AI-based defect analysis, along with a feature to predict anomalies in the production line.

A representative from Hanul Semiconductor remarked, "With the recent expansion of AI servers, autonomous vehicles, and electric cars, quality standards have tightened. The shift from sampling inspections of a portion of the production to comprehensive inspections of all products is becoming the new standard. This system combines high-speed ultrasonic inspection technology with AI-based defect analysis to achieve both comprehensive inspection and productivity."
