Mobile phone chip supplier pattern and chip localization development history, existing problems and future trends analysis

In order to enhance the security of communication information and reduce China's reliance on imported chips, this paper first examines the current state of smartphone chips and their supplier patterns. It then analyzes the development of chip localization from both design and manufacturing perspectives, identifying existing challenges and forecasting future trends. Introduction A chip is a semiconductor component that serves as a carrier for integrated circuits, typically fabricated on a wafer. The first practical single-chip integrated circuit was developed by Fairchild in 1960. Today’s chips represent the advancement of VLSI technology. According to Gartner, global semiconductor revenue surpassed $400 billion in 2017. IC Insights reported that in 2016, the top 20 global semiconductor companies included 8 from the U.S., 3 each from Japan, Europe, and Taiwan, 2 from South Korea, and none from mainland China. Among these, 3 were pure foundries, 5 were chip design firms, and the rest had capabilities in both design and manufacturing. This list reflects the competitive landscape of the global chip industry. Key areas of focus include 10 nm and smaller manufacturing processes, 4G+/5G technologies, high-performance low-power mobile platforms, large memory chips, IoT, and automotive connectivity. IP, advanced manufacturing/packaging, key equipment/materials, and technical talent are major barriers to competition. According to statistics, China imported $227.1 billion worth of ICs in 2016, highlighting its high level of external dependence. Under national policy guidance, the domestic IC industry has shown steady progress. This paper outlines the development of the smartphone chip industry chain, analyzes current conditions and challenges, and predicts future trends. National Policy Support Chips play a crucial role in the smartphone industry, which is a cutting-edge sector of manufacturing and a symbol of advanced technology. Recognizing the importance of the chip industry and China’s lagging position, the Ministry of Industry and Information Technology introduced the National Integrated Circuit Industry Promotion Program in 2014. This program outlined global trends, China’s industrial status, and set priorities for development, focusing on design, manufacturing, packaging/testing, and breakthroughs in key equipment and materials. The outline also set medium- and long-term goals: by 2020, the gap with international standards would narrow, sales growth would exceed 20%, and the industry ecosystem would take shape. By 2030, key sectors would reach international levels, with several enterprises entering the global top tier. To support this, multiple industrial funds were established at both central and local levels, with target scales exceeding 300 billion yuan. Local governments also introduced policies to promote projects. Mobile Phone Main Chip and Major Suppliers Smartphones are complex devices integrating various components. The main chips used today include application processors (AP), baseband chips, RF chips, memory chips, camera chips, display/touch chips, fingerprint sensors, power management chips, and connection chips like Wi-Fi and Bluetooth. Some models also feature dedicated audio or image processing chips. Major suppliers include companies such as Qualcomm, MediaTek, Samsung, and Huawei. While foreign firms lead in technology, patents, and market performance, Chinese companies have made significant strides in certain areas. Progress in Mobile Phone Chip Localization The semiconductor industry operates under two business models: IDM (Integrated Device Manufacturer) and vertical division. IDMs like Intel handle all aspects of production, while fabless companies like Qualcomm outsource manufacturing to foundries such as TSMC and SMIC. IP providers like ARM also play a vital role. Although globalization has reduced the concept of localization, it remains critical for national security. “Domesticization” refers to having independent IP and core technologies, with control over operations. Chip Design Chip design is a key part of the semiconductor industry, with relatively lower R&D costs and technical barriers. Domestic manufacturers like HiSilicon and Spreadtrum have made progress, but most remain in niche or low-end markets. Memory chips, however, remain dominated by foreign firms due to higher technical and capital requirements. Chip Manufacturing SMIC is a leading domestic manufacturer, providing services from 0.35 μm to 28 nm. Despite growth, it lags behind international standards by 2–3 generations. Partnerships with companies like Qualcomm and Huawei aim to close this gap. Packaging and testing firms like Changdian Technology have also made advances, entering the global top three. Problem Analysis and Future Prospects Current challenges include limited breakthroughs, weak industrial chains, lack of core technology and talent, low-level competition, and foreign dominance. International giants like TSMC and Qualcomm are expanding their presence in China, presenting both opportunities and threats. Future prospects involve continued government support, improved talent training, and efforts to build a complete domestic supply chain. With strategic planning, China aims to achieve higher self-sufficiency in smartphone chips. Conclusion This paper highlights the progress and challenges in smartphone chip localization, emphasizing the need for innovation, collaboration, and long-term strategy. Further research into key technologies, market performance, and resource allocation can help develop metrics like the "Mobile Phone Chip Localization Index."
