By the close, the semiconductor equipment ETF Wanjia (159327) rose 5.17%, reaching a new high with a trading volume exceeding 190 million. As of the previous trading day, the semiconductor equipment ETF Wanjia (159327) had a weekly increase of 9.25%, a monthly increase of 34.38%, a six-month increase of 66.72%, and a yearly increase of 140.69%. The past performance has been outstanding. Against the backdrop of the AI computing power explosion, the demand for 800G, 1.6T, and even 3.2T optical modules for SOI is growing exponentially. CITIC Construction Investment Securities believes that by 2026, the demand for 800G optical modules is expected to continue to grow rapidly, while the shipment scale of 1.6T will also see significant growth, and the R&D of 3.2T optical modules has officially begun, with various technical routes such as fast and narrow and slow and wide having considerable opportunities. The investor relations activity record of Shanghai Silicon Industry indicates that this year, 12-inch SOI will enter the mass production stage for the first time, with some products already relatively mature and beginning mass production. Currently, customers are mainly domestic and can be widely applied in silicon photonics, radio frequency, high voltage, and other fields. Everbright Securities' research report points out that AI data centers are driving storage demand, and the global semiconductor material market scale continues to increase. Driven by the demand for AI computing power, storage chips are accelerating their evolution towards higher stacking layers, significantly increasing the manufacturing process steps and material consumption for each chip. Meanwhile, global wafer fabs are in a large-scale capacity expansion cycle, and the continuous release of new wafer capacity will directly drive the procurement demand for upstream semiconductor materials.
