SK Hynix Proposes Major DRAM Wafer Capacity Expansion to Double Production and Reach One Million Monthly Sheets Through Yongin and Cheongju Semiconductor Clusters
SK Hynix is proposing a challenging, long term production expansion to its main equipment and material suppliers to double its DRAM wafer capacity. As detailed in South Korean semiconductor industry news outlet, TheElec, the chipmaker is seeking to raise its monthly wafer inputs from 550,000 sheets to roughly 1,000,000 sheets early in the next decade. This ambitious, long term roadmap was already established well before major industry developments brought widespread public awareness of a potential memory shortage.
This ambitious expansion fits public calls from top customers. Nvidia CEO Jensen Huang recently etched out an explicit call for additional advance memory at an industry exhibition by signing a message on an SK Hynix wafer.
And further in that respect, SK Group Chairman Chey Tae won signaled the conglomerate's ambitions as it looks to roughly double its total wafer processing capability within five years. This planned scaling will create more stability within the supply chain for AI hardware without inducing major price shocks in the market.
To reach the full 1,000,000 wafer input, SK Hynix is targeting its capital investments in the Yongin semiconductor cluster and the ongoing construction of the Cheongju M15X facility. The current 550,000 wafer baseline is supported by roughly 200,000 wafers a month from its Wuxi, China facility. The new Yongin 1st Fab will be split into six individual cleanrooms. Equipment will begin entering the factory for the Phase 1 installation later this hardware cycle, and the company is forecasting 60,000 DRAM wafers a month for each consecutive cleanroom brought online. This will add 360,000 new DRAM wafer input capacity to the grid from the Yongin cluster alone by 2030.
An additional 40,000 wafer input will be coming from its Cheongju M15X fab beginning later this year, increasing to 80,000 wafers a month by next year. The combination of the Yongin and Cheongju facilities would enable SK Hynix to hit its target of 1,000,000 wafers per month input. Although every cleanroom being added is for DRAM, SK Hynix has stated its NAND business will be scaled through technological enhancements and layer increases rather than through added wafer input capacity.
While its equipment suppliers are likely thrilled by the prospect of huge orders, most suppliers are responding with caution due to SK Hynix's aggressive timetable. Parts suppliers know the volatility of the semiconductor industry, as some lost a significant portion of their revenues when SK Hynix dramatically slashed its equipment orders in the wake of its recent massive inventory build up. With only six month gaps in the proposed rollout of new capacity, there is very little buffer time built into the supply chain, and a holdup in one piece of equipment would jeopardize the entire cleanroom schedule.
Even with these anxieties in the market, SK Group leaders appear determined to proceed with the expansion no matter what happens in the short term market dynamics. Chairman Chey Tae won recently stressed the importance of sustainability within the industry, arguing that consistent supply levels, rather than temporary market spikes, would create a healthier environment.
Price spikes or increases can harm the overall sustainability of the market ecosystem. The market needed more sustainability for the whole ecosystem.
The underlying belief of this plan seems to be to capture a permanent slice of the AI memory market rather than riding a temporary market upturn.
