According to the Industrial and Commercial Times, with the expansion of HBM and advanced logic below 2 nanometers, it is estimated that the global silicon wafer supply-demand gap will widen from about 8% by the end of 2026 to 15% in 2027 and 24% in 2028. GlobalWafers, Siltronic, and TSMC are expected to benefit from this. It is noted that mid-2027 will be a critical turning point; if the pace of supply expansion does not keep up, a new wave of shortages and rush buying may occur from the second half of 2027 to the first half of 2028.SEMI statistics show that the global silicon wafer shipment area reached 3.573 billion square inches in the second quarter of 2026, an increase of 9.1% quarter-on-quarter and 7.4% year-on-year. It is estimated that the global monthly production capacity of 12-inch silicon wafers will be about 10.69 million pieces in 2026, an increase of 7% year-on-year, with only about a 3% increase to 11 million pieces in 2027, and an increase of about 6% to 11.7 million to 11.76 million pieces in 2028. The new supply includes about 300,000 pieces from the second phase of GlobalWafers and about 100,000 pieces from Siltronic.It is estimated that the consumption of HBM silicon wafers will increase by 23% and 28% in 2027 and 2028, respectively; new general DRAM production capacity will gradually come online starting in 2027, with an additional monthly capacity of about 350,000 to 450,000 pieces by 2028. In terms of advanced logic, the consumption of logic process silicon wafers is expected to increase by 12% and 11% in 2027 and 2028, respectively. Currently, customer silicon wafer inventory remains at about 100 to 120 days, and it will take time to digest to the normal level of 50 to 70 days.

According to the Economic Daily, semiconductor silicon wafers have seen a significant price increase for the first time since the COVID-19 pandemic, covering the full range of specifications including 6-inch, 8-inch, and 12-inch, with an increase starting at 10%. Industry insiders believe this is the first price adjustment in over three years, and major Taiwanese silicon wafer suppliers such as GlobalWafers, TSMC, and Hejian are expected to see improvements in revenue and profitability.GlobalWafers stated that recent demand in some end markets has gradually improved, inventory adjustments in the supply chain are healthier than in the past, and market signals are more positive than last year, but prices still depend on the product, specifications, and customer situations. TSMC mentioned that under cost pressures and demand support, they have begun communicating price adjustments with customers, and operations in the second half of the year are expected to outperform the first half. Hejian indicated that they are actively negotiating price adjustments with customers and continuing to promote advanced packaging and related products.Industry analysis suggests that this round of price increases mainly reflects the rebound in chip demand driven by AI, with increased usage in advanced and mature processes, allowing the upstream silicon wafer industry to gradually feel the recovery. Currently, the negotiation progress varies among factories and customers, with some 12-inch polished wafers already subject to new quotes with double-digit percentage increases, and discussions for 8-inch and 6-inch products are also moving in a similar upward direction.

According to the South Korean media The Elec, GlobalWafers stated during the Q2 earnings call that the production lines for 12-inch, 8-inch, and 6-inch wafers are nearing full capacity, with some advanced 12-inch products experiencing supply constraints due to a surge in demand for AI chips, HBM, and advanced packaging. Shin-Etsu Chemical achieved double-digit growth in 12-inch shipments both year-on-year and quarter-on-quarter in Q2, and Sungrow also believes that customer inventory adjustments are nearing completion. Although SK Siltron is gradually releasing capacity from new production lines, it is still difficult to meet the growth rate of orders.Tight supply is driving changes in long-term contract models, and GlobalWafers signed a 10-year LTA (including advance payment) with Micron last month. Prices in the non-LTA market have begun to rise and are expected to continue to increase in the second half of the year. GlobalWafers stated that it is negotiating with customers to incorporate price adjustment mechanisms into new contracts, and Nexchip also emphasized the need for "broad and meaningful price increases" to support reinvestment. Industry insiders expect that as new factories from Samsung, SK Hynix, and Micron come online, wafer demand will double in the second half of 2027, and supply shortages may further intensify.
