At present, global chip prices are rising, and display driver chips are also facing the same price increase. The current production capacity in the industry chain is mixed. In the chip design link, although the price increase of display driver chips is conducive to the acquisition of downstream foundry capacity by related design companies, CIS, PMIC and other products continue to occupy mature process capacity, and the market continues to place panic orders; in the wafer manufacturing link , Although the new production capacity of Nexchip, SMIC and other factories is gradually released, "black swan incidents" frequently occur, such as: UMC Hsinchu 8-inch wafer fab blackout, Texas blizzard caused Samsung Line S2 to be affected and NXP and Infineon mature The manufacturing process is also affected.
CINNO Research categorizes global DDIC wafer capacity requirements according to process processes. Data shows that the 90/80nm process segment has always maintained the highest proportion, with a supply ratio of 26-30%. At the same time, the 28nm market demand is gradually increasing. Global DDIC wafer production capacity is expected to increase by 13% year-on-year in the fourth quarter of 2021.
my country shows that the dependence on foreign imports of special chips is relatively high. According to CINNO Research industry research data, in 2020, the global DDIC wafer capacity supply will account for 61% of the global DDIC wafer capacity supply, and about 13% of China’s mainland capacity. In the future, with Hefei With the expansion of Jinghe and SMIC's production capacity, it is estimated that in 2021, Taiwan's production capacity share will be slightly reduced to 58%, and China's production capacity share will increase to 20%.
Observing the future strategies of major foundries, TSMC’s 8-inch production capacity is gradually shifting to high-margin products, SMIC and Hua Hong continue to increase DDIC-related production capacity, and Samsung and Hynix will tighten DDIC-related production capacity. CINNO Research predicts that the global DDIC supply-demand ratio will gradually ease to 1.10 in 2022, and the value will be 1.01 in 2020. However, as the price of display driver chips drops, the global industry supply-demand relationship will still face adjustments. The supply and demand situation between 2023 and 2025 may be tight again, and industry supply and demand will show a trend of cyclical fluctuations.
