According to statistics from the China Semiconductor Industry Association (CSIA), the sales revenue of China's semiconductor industry in 2022 amounted to 1.2 trillion RMB (US$171.4 billion; US$=7 RMB). Among them, the proportions of IC design industry, IC manufacturing industry, and IC packaging and testing industry in the total sales revenue were 43%, 32%, and 25%, respectively. The IC packaging and testing industry was one of the early semiconductor sub-industries to be developed in China. Before 2016, China's IC packaging and testing industry consistently held a leading position in the semiconductor industry. However, due to the rapid expansion of the IC design and wafer foundry industries, the proportion of the IC packaging and testing industry in China's semiconductor industry revenue has decreased. This report provides an overview of the development of the IC packaging and testing industry in China, focusing on aspects such as market size, changes in industry structure, and the dynamics of major players.
