Report: SK hynix accelerates equipment investment schedule, further expands HBM4 capacity
IT之家, November 15: According to a report by Korean media Etnews today, despite factors such as the CEO change at 英伟达 increasing uncertainty in the AI industry, SK hynix still believes demand for HBM (IT之家 note: high-bandwidth memory) remains strong. The company plans to focus investment on equipment for HBM packaging and testing, and plans to officially put it into use in the first half of next year.

According to multiple semiconductor equipment industry sources, SK hynix is discussing the procurement of HBM4 production equipment with partners. The company is mainly coordinating purchase timing and quantities with equipment suppliers responsible for back-end processes such as HBM bonding, cutting, and inspection.
A SK hynix partner familiar with the matter said: "SK hynix is pushing forward additional investment in HBM4 production equipment and accelerating related arrangements, with the goal of completing equipment move-in and installation and commissioning in the first half of next year." It is learned that SK hynix plans to accelerate the equipment investment schedule, and for some equipment, suppliers are even required to complete delivery before the first quarter.
Meanwhile, the additional production base for SK hynix's capacity expansion may be selected at the P&T6 packaging and testing plant in Cheongju, North Chungcheong Province, South Korea. This semiconductor plant was formerly called M8 and was selected by SK hynix in 2025 as an HBM production base. Since the beginning of this year, SK hynix has been building HBM production lines there.
Another industry insider said: "SK hynix plans to use the idle space at the P&T6 plant as much as possible to expand HBM4 capacity. If the entire plant operates at full capacity, it can additionally produce more than 20,000 HBM wafers per month."
At its third-quarter earnings briefing last month, SK hynix said: "Through 2029, the company's DRAM and HBM capacity for the next three years has in effect been completely sold out."
