Seoul, South Korea – Raon Robotics unveiled a novel line of vacuum robots utilizing direct-drive (DD) motors at the Semicon Korea 2026 trade show, signaling an aggressive push into the global semiconductor wafer handling market. The company showcased upgraded models of its VACTRA-Q, a four-arm, seven-axis robot, and the VACTRA-D, featuring two five-axis arms, both now incorporating the DD motor technology.
The core innovation lies in the elimination of traditional gearbox systems, a move designed to significantly reduce vibration and particle generation – critical factors in semiconductor manufacturing. According to Raon Robotics, the DD motor implementation cuts vibration by more than 50% and boosts throughput by 20%, enhancing precision and overall productivity. The company has also incorporated a magnetic fluid sealing structure to minimize particle contamination in sensitive processes.
“Our company’s core focus is on semiconductor wafer handling solutions,” stated Kim Won-kyung, CEO of Raon Robotics, in an interview at the exhibition. “Our goal is to become a global top-tier company.” This ambition is fueled by a growing demand for advanced automation in semiconductor production, particularly as manufacturers seek to increase efficiency and yield.
Raon Robotics has spent over two decades specializing in wafer transfer robots, primarily focusing on transfer modules (TM) used to move wafers within vacuum chambers. The company has steadily increased its market share domestically, competing with established American and Japanese firms, and is expanding its presence in China through collaborations with leading equipment manufacturers. Some Chinese partners are already implementing the robots in overseas production lines, according to the company.
The introduction of the DD motor technology represents a significant investment for Raon Robotics, which rebranded from RaonTech earlier this year. The company reported a 58.4% increase in operating profit last year, reaching 3.93838 billion Korean Won, driven by increased semiconductor investment and a diversified customer base. A cash dividend of 200 Korean Won per share was approved for shareholders, representing a 1.9% dividend yield.
Raon Robotics’ revenue is heavily weighted towards the semiconductor sector, accounting for approximately 91.8% of its total income. The remaining portion comes from other sources, such as contract manufacturing. This reliance on the semiconductor industry means the company’s performance is directly tied to the cyclical nature of the market and the demand for robotic automation.
The company is actively pursuing partnerships to expand its reach. Kim Won-kyung indicated that a comprehensive product lineup is essential for competing on a global scale, and the Semicon Korea 2026 exhibition is viewed as a key opportunity to accelerate expansion plans.
