Group 1 - China is the largest panel production and R&D center globally, with over 60% of the world's flat panel display capacity [1][2] - The upstream core material, photomask, is currently monopolized by manufacturers from the US, Japan, and South Korea, while domestic companies like Qingyi Optoelectronics and Luvi Optoelectronics are improving their market penetration [1][2] - Photomasks are critical materials in the manufacturing process, with a significant cost share in semiconductor production, accounting for approximately 13% of the total material costs [1] Group 2 - The revenue scale of domestic photomask manufacturers is relatively low, and there is a need for increased market penetration [3] - The domestic semiconductor photomask market is projected to reach approximately 18.7 billion RMB by 2025, with wafer manufacturing photomasks expected to account for 10 billion RMB [3] - Domestic manufacturers are in a phase of continuous technological upgrades and the release of new high-end capacities, with photomask penetration expected to increase significantly [3]
