What is the pattern of the domestic chip testing market?

It has to be said that the cake of almost all chip industry chains is huge, and chip testing is no exception. According to Gartner Consulting and CLSA’s forecasts, it is concluded that by 2025, the global chip test service market is expected to reach 109.4 billion yuan, of which the Chinese chip test service market will reach 55 billion yuan, accounting for 50.3%, and there will be more than 250 billion in 5 years. Billions of huge room for growth.

Chip testing mainly includes two aspects of testing, wafer testing CP and finished product testing FT. Wafer testing CP is particularly important in multi-chip packaging scenarios, which can effectively avoid the failure of a single chip to cause other chips to be “buried” together; The FT test can effectively screen out the damaged chips during the packaging process. Both of them work together to ensure the final chip quality. For high-end chips such as 7nm, 5nm, and 3nm, chip testing is more important. It can achieve a closed loop from R&D to mass production and guide chip design.

Of course, the equipment used in different testing processes is also different. In the wafer testing stage, the testing machine and probe station are mainly used, and the testing machine and sorting machine are used in the finished product testing stage. In the entire ranks of test equipment, ATE is the core equipment for chip testing. Now, especially for high-end chips, ATE test equipment is needed to ensure production. The total scale of the chip ATE automated test equipment market alone has reached 7 billion U.S. dollars.
