China Target Chiplet, will it be a shortcut for China semiconductor self sufficiency？

China is focusing on chiplets to close the gap with international manufacturers. Amid no letup in US-China tech tensions, many Chinese are pinning their hopes on the concept of a chiplet as a replacement for standard chips to help the country achieve greater self-sufficiency in semiconductor manufacturing. The chiplet is essentially a technology that allows an integrated circuit block to be interconnected with other ICs to form a larger, more complex chip. 

For China, chiplet technology is particularly appealing because it opens up the possibility of incorporating a series of 14-nanometre node chips- which the country can produce- with other chips it cannot produce, to create a more powerful semiconductor that is equivalent to an advanced 7nm or even 3nm node chip, which could help reduce the impact of US trade sanctions. The chiplet has gained popularity in China as the country's semiconductor manufacturing is years, if not decades, behind international fabs such as TSMC and Samsung Electronics when it comes to making advanced chips. 

With US trade sanctions on the export of advanced chip technologies to China unlikely to lift any time soon, a number of Chinese researchers have argued that the chiplet could be an option for the country to forge its own path in advanced chipmaking. Even Huawei has recently joined its R&D camp. So can chiplets really solve China's semiconductor crisis? What is the current development of chiplets in China? What are the advantages of chiplet?
