Recently, a number of policies for Chengdu to speed up the high-quality development of the integrated circuit industry (draft for soliciting opinions) have been issued. "several policies" point out that this policy focuses on supporting 12-inch advanced production lines with a linewidth of less than 28 nanometers, as well as characteristic process production lines such as compound semiconductors and digital-analog hybrid circuits. Chip design and development projects in the fields of information and communications, general computing, high-end storage, intelligent sensing, chip-level, wafer-level, system-level, three-dimensional packaging and other advanced packaging and testing industrialization projects, As well as supporting key equipment and materials industrialization projects.
