HHAT Business Summary

Hua Hsu Advanced Technology Co., Ltd. (HHAT), formerly known as Hua Hsu Silicon Materials, operates as a specialized manufacturer in the semiconductor and solar energy supply chains. The company generates revenue through a transaction-based model centered on the production and sale of electroplated diamond wires, which are critical for high-precision cutting of hard and brittle materials such as sapphire, silicon, and magnetic substrates. Its primary business segments include Diamond Wire Manufacturing and Wafer Services, the latter of which encompasses silicon reclaim, test wafer production, and epitaxial (epi) wafer fabrication. HHAT has recently expanded its footprint into the compound semiconductor market, offering wafer recycling and advanced material processing to enhance resource efficiency for chipmakers. Within the competitive landscape, HHAT contends with major regional players such as Phoenix Silicon International Corp (PSI), Saultech Technology, and Materials Analysis Technology, positioning itself as a high-density niche specialist focused on the intersection of advanced cutting tools and circular semiconductor manufacturing. HHAT is led by Chairman Huang Wen-rui, who also serves as the company’s primary spokesperson and brings extensive experience in the optoelectronics and industrial materials sectors. The executive leadership team includes General Manager (CEO equivalent) Tseng Shih-chueh, who oversees the firm's operational strategy and recent pivot toward advanced technology applications, and Deputy General Manager Liu Hsiang-Lin, who manages technical execution. Financial oversight is directed by Wang Yu-hsiang, the Finance and Accounting Supervisor. The company’s governance is managed by its 7th Board of Directors, elected for a term spanning May 2025 to May 2028, which emphasizes a strategic focus on R&D and market expansion into the Greater China and Southeast Asian regions. Notable institutional support and board-level expertise are concentrated in Taichung, Taiwan, where the company maintains its headquarters and primary manufacturing facilities.
