Samsung Plans to Double HBM4 Memory Production Next Year

Samsung Electronics plans to more than double its output of HBM4 and HBM4E high-bandwidth memory chips next year, a strategic expansion driven by surging demand from artificial intelligence workloads and advanced GPU manufacturers. According to semiconductor industry sources, the company will increase wafer input to approximately 250,000 next year, up from roughly 180,000 currently, with the HBM4 product family accounting for an estimated 80 percent of total shipments, a significant rise from its current 40 percent share. To support this production ramp at its Cheonan manufacturing campus, Samsung is scaling its supply chain for glass carriers, essential substrates that temporarily reinforce HBM DRAM wafers during precision thinning and drilling processes. As chip designers pursue 12-layer and higher stacking configurations to maximize bandwidth within strict thickness constraints, wafer warpage and fracture risks increase substantially. Samsung intends to raise outsourced glass carrier cleaning volumes to 50,000 sheets monthly by next year, a 2.5-fold increase from the 20,000 sheets processed this year and a fivefold jump from last year baseline. Industry analysts note that even with carrier reuse and varying process yields, this supply chain expansion strongly indicates an anticipated output growth of at least 200 percent. The production acceleration follows key milestones achieved earlier this year. In February, Samsung commenced mass production shipments of sixth-generation HBM4 utilizing 10-nanometer-class DRAM and a 4-nanometer base die. By May, the company had begun delivering 12-layer HBM4E samples to major technology clients, including Nvidia. These developments, highlighted during recent shareholder engagements at Samsung's Suwon headquarters, underscore the company's strategic pivot toward higher-margin advanced-memory solutions as it competes to capture a larger share of the enterprise AI infrastructure market. Executives and industry observers emphasize that Samsung is deliberately prioritizing high-value HBM4 variants within its manufacturing mix. The coordinated expansion of both production capacity and specialized materials handling positions the semiconductor giant to capitalize on the accelerating deployment of next-generation AI accelerators. With supply chain commitments already underway and customer qualification progressing, Samsung's HBM roadmap signals a decisive push to solidify its competitive standing in the high-performance memory segment over the coming fiscal cycle.
