Hanmi Semiconductor plans to establish Hanmi USA, a wholly owned subsidiary in San Jose, California, with a $1.5 million investment, or about 2 billion won, and target an official launch in the fourth quarter. The unit will handle development and sales of semiconductor manufacturing equipment, parts and materials, plus technical support and maintenance for local customers, as the company responds to rising AI semiconductor demand and seeks to reduce reliance on a small number of buyers. The move follows a strong second-quarter rebound after a weak first quarter linked to delayed HBM4 orders: second-quarter revenue hit a record 251.1 billion won, with operating profit of 130.3 billion won and a 51.9% operating margin. Hanmi said customer diversification, including business with Micron alongside SK Hynix, helped cushion volatility and supports its push to expand beyond memory-focused TC bonders into 2.5D packaging tools for foundries, OSAT providers and AI chip customers.
