[Samsung wafer foundry: 4nm production capacity is full, 5nm is taking over to attract customers, and 2nm negotiations are lagging behind] "Science and Technology Innovation Board Daily" reported on the 21st that it was reported that the yield rates of Samsung's 4nm and 5nm processes are relatively stable. Due to the recent surge in customer orders, the 4-nanometer process production capacity of Samsung Electronics' wafer foundry business unit is close to saturation. The company is increasing sales efforts and striving to win more customers for its 5-nanometer process. It is reported that the 5-nanometer process can also improve the utilization of existing production facilities. Industry insiders expect that the improvement in 4-nanometer process utilization and new 5-nanometer orders will help improve the recent performance of Samsung wafer fabs. In contrast, Samsung still faces challenges in winning important customers on its next-generation flagship 2nm process. Samsung Electronics is negotiating semiconductor production contracts based on the 2-nanometer process with major global technology companies, but some negotiations are lagging behind. Since cutting-edge processes require not only verification of yield, but also comprehensive verification of energy efficiency, intellectual property rights, and stable mass production capabilities, it takes a long time from signing a contract to achieving mass production.
