Is highly unlikely that they will be one. I think the lockdown era is over.

Lockdown only 2 months. Why delayed by 1year？
Saiwei Electronics is deploying a "dual cycle" foundry service system with both "process development" and "wafer manufacturing" functions at home and abroad to meet the needs of domestic and foreign customers. Pilot test and mass production requirements.
He pointed out: "Semiconductor is a long-term industry, and it is an asset-heavy feature for manufacturing. You can't stop all the actions just because the short-term market is bad. Production capacity construction, equipment procurement, cost control and other aspects should be further optimized in advance, so as to be more prepared when the market picks up."
In China, Saiwei Electronics Beijing FAB3 is a mass production line with a total design capacity of 30,000 pieces/month. At present, the first-phase production capacity of 10,000 pieces/month is almost completed, and the second-phase production capacity of 20,000 pieces/month is also under construction. in progress. In addition, Saiwei Electronics also plans to build a pilot test line with a production capacity of 3,000 pieces per month in Beijing and the Greater Bay Area. It is a MEMS advanced packaging and testing line for 10,000 pieces/month.

The success is now depends on when US will finally make Japan and Netherlands to join sanction on china.
Radiation hardened chips are less focused on the physical shielding of the chip with iron/lead/steel/etc (though they do have shunts that minimize ESD damage typical in high RAD environments), but primarily on 2 areas:
Error detection and recovery - similar to , but instead of guaranteeing data integrity, the radiation hardened chips assures computational integrity. This is done through methods such as having parallel circuits in the chip that both run the same instruction and checking if the outputs match or logic that runs the instructions multiple times and comparing the results. If the results are different(signaling radiation interference), then the chip itself reconciles the differences so the software doesn't crash or get invalid results.
Gate design differences - logic gates are typically larger or work at higher PN junction thresholds or use different doping agents to make them physically less susceptible to having a computational error when struck with a high energy particle.
If you have no idea what you are talking about, then please just read other people's posts and keep quiet.
That was not a response, but a warning. You have been polluting this thread with some awful posting. I already warned you once about all these Russian related stuff, but your posting haven't gotten any better here. This is a final warning for you to clean up your act or else I will delete any future posts you have on this thread.
Alternatively, SpaceX use multiple commercial grade flight computers so they don't need radchips.

SpaceX uses an Actor-Judge system to provide triple redundancy to its rockets and spacecraft. The Falcon 9 has 3 dual core x86 processors running an instance of linux on each core. The flight software is written in C/C++ and runs in the x86 environment. For each calculation/decision, the "flight string" compares the results from both cores. If there is a inconsistency, the string is bad and doesn't send any commands. If both cores return the same response, the string sends the command to the various microcontrollers on the rocket that control things like the engines and grid fins.
All flight computers on all aircraft and spacecraft are triple redundant, it is the absolute minimum for avionics regardless of RADHARD requirements. Here's an example of the published flight control system of the Boeing 747 which flew in the 1970s and was published in the 1990s.
They still make chips RADHARD for a reason.
Understand the issues, the errors, etc.
To lay out the semiconductor industry, West Shanghai plans to acquire 0.7867% of the equity of Gona Semiconductor for 10 million yuan
West Shanghai Automotive Service Co., Ltd. intends to use its own funds of no more than RMB 10 million to acquire 0.7867% of the equity of Shanghai Gona Semiconductor Technology Co., Ltd. held by Shanghai Jinpu Phase II Intelligent Technology Private Equity Investment Fund Partnership (Limited Partnership), And has signed the "equity transfer agreement".
Shanghai Guona Semiconductor Technology Co., Ltd. is a high-tech company focusing on R&D, production and sales of complete wafer transfer equipment modules (EFEM semiconductor equipment front-end module/SORTER wafer sorting equipment) and key components. The wafer transfer module is an essential part of all semiconductor manufacturing processes and testing equipment. At present, the high-end models of this equipment are monopolized by foreign suppliers.
Ms. Ye Ying, the founder of Gona Semiconductor, led the team, combined with her own industry experience and technical strength, chose the field of wafer transmission, and established Gona Semiconductor Technology Co., Ltd. The project R&D team is from well-known integrated circuit equipment companies at home and abroad, mastering independent core Technology, the technical level is leading domestically. With the recognized team strength in the industry, nearly 30 mainstream equipment companies and nearly 20 fabs have become customers of Gona Semiconductor.
On December 7, the foundation stone laying ceremony for the complete machine module and key components of Gona Semiconductor wafer transfer equipment was held in Haining Economic Development Zone. The total investment of the project is 230 million yuan and the total land area is 40 mu.
