Complementary advantages: jointly building an industrial collaborative ecosystem
Sitan is deeply involved in the research and industrialization of Micro LED technologyCMOS driver chipHigh precision bonding solution, white light integration process, module packagingHaving profound technical accumulation and product matrix in key links. In the field of in car Micro LED, Sitan has a forward-looking layout of Die to Die/Wafer technology, combined with AM drive mode and fully customized drive technology, effectively reducing the cost of large-sized chips and modules in cars, matching the core requirements of high yield, high reliability, and long life. At present, Sitan's in car Micro LED products have obtained targeted development contracts and mass production orders from international top Tier 1 suppliers, with key performance indicators leading the industry.
As a leading semiconductor optoelectronic enterprise, Qianzhao Optoelectronics has significant advantages in the field of Micro LED epitaxial wafers and light-emitting chips, with large-scale manufacturing and industrialization capabilities, providing strong support in key processes such as epitaxial growth and COW technology. In the field of automotive Micro LED, Sapphire epitaxy, with its core advantages of high technological maturity and strong working condition reliability, is more suitable for harsh application scenarios such as high temperature and vibration in vehiclesWith years of industry experience and process accumulation in the field of high quantum efficiency sapphire substrate epitaxial technology, Qianzhao Optoelectronics hasAdaptive high beam (ADB) upstream core supply strengthWe have established an integrated self-developed and mass-produced system from epitaxial growth to LED light-emitting chips, and have completed the technical reserves for automotive lighting and display chip level solutions.
Car display is one of the potential large-scale application scenarios for Micro LEDs. Vehicle grade applications have strict requirements for high temperature resistance, earthquake resistance, reliability, yield, and cost of components. From the perspective of technological maturity, mass production yield, and vehicle compliance,At present, the combination of Die to Die/Die to Wafer technology and sapphire epitaxial route is more suitable for the commercialization of automotive Micro LEDsBoth parties are building long-term strategic layouts in this field, with technology routes in line with automotive standards. This cooperation can leverage the differentiated advantages of the industrial chain, break down technology and production capacity barriers, and accelerate the mass production and landing of micro LEDs in vehicles.
Same city resonance: helping Xiamen's industry leap forward
Xiamen Torch High tech Zone is a benchmark for the domestic semiconductor industry. Sitan and Qianzhao Optoelectronics are both core enterprises in the park. This cooperation will connect the entire industry chain from Micro LED epitaxy, chips, drivers, integration, detection to terminal applications,Further enhance the level and competitiveness of Xiamen's new display and semiconductor industry.
This strategic cooperation is an important layout for Sitan to accelerate the industrialization of in vehicle Micro LED/optical communication, deepen industry chain collaboration, and enhance product competitiveness. In the future, Sitan will adhere to the concept of open collaboration, work with more industry chain partners, consolidate the manufacturing system through technological complementarity, enhance mass production capabilities through supply chain collaboration, broaden application scenarios through ecological co construction, and assist in the scale, high-end, and global development of Micro LED industry.
