The Chinese market accounts for a third of global semiconductor sales, the largest share, equivalent to the United States, the European Union and Japan combined, but mainly because China is the world's manufacturing center, especially computer and mobile phone production, the largest consumption of chips. With the rapid development of artificial intelligence, as well as 5G, Internet of Things, energy conservation and environmental protection, new energy vehicles and other strategic emerging industries, the demand for semiconductors continues to increase. The scale of China's semiconductor market demand is expected to expand further in 2020, with the market demand expected to reach 1985 billion yuan. In order to better promote the exchange and interaction of the semiconductor industry and enhance the internationalization of the semiconductor industry, the 2021 China (Shanghai) International Semiconductor Exhibition (CDISEE-2021) will be held on November 2-4, 2021 at the Shanghai New International Expo Center. CDISEE-2021 is divided into exhibitions, summit forums and academic conferences, is the semiconductor industry's annual event, but also the semiconductor industry and related industry exchanges and cooperation of a comprehensive professional display platform.
