Chinese semiconductor industry

SPARC is open source and there are many high end chips based on that. After ARM banned license to Russia it didn't harm MCST's chips which are SPARC. It would be interesting to see if China develops chips based on SPARC.

Why would anyone in China jump into another legacy architecture when they already have LoongArch/Mips?

alright, this is the second time you've mentioned SPARC, so let me just stop you know. No Chinese design shops are working on SPARC. The desktop CPUs will continue to use x86/ARM designs. Maybe more resources and support will be thrown at Loongson and LoongArch. HPC and smartphone CPU will slowly migrate from ARM to RISC-V. All the MCUs and everything else will move to RISC-V. No SPARC.

Monopoly never lasts forever. Chinese tried to keep the technology of making silk a secret. Eventually Romans reverse engineered silk technology. Western people cannot keep semiconductor technology a secret forever. Eventually Chinese and Russians will learn it.

I have a sense of feeling that Chinese are ppl who will excel in semiconductor field given good resources and management. China must make country -wide effort to break this rope.

Typically for hard semiconductor though CVD and ALD is preferable since highly precise control of deposition rate and shape ie conformal coating or selective coating is possible. Sputtering PVD is fast for metal deposition but not as controllable. But MBE neither shares the control of CVD/ALD nor the speed of sputtering. Looks like this is for 3rd generation semiconductor AKA not Si though, so maybe some sort of lattice matched III-V heterostructure is what they're going for. That would mean RF or optoelectronics.

How's China doing on CVD, ALD, and PVD?

Kind of a noob question here, but from what I understand programs are written based on a particular OS, and then simply compiled to suit whichever instruction set the user's CPU is using, is that correct?

Does that mean instruction set doesn't really matter for the end user, since the OS and programs available will be similar?

For the most part, people just see things from an APP perspective though so availability of software for a particular line of instruction set + OS is prob the highest importance. The more popular a Arch/OS, the more users and developers it will attract. Others are speed performance on the architecture and energy efficiency of architecture. For example ARM has always been more energy efficient hence the adoption in the mobile space over Intel. Intel had the lead in desktop because of performance for a long time until Apple introduce the M ARM which had both performance an battery efficiency.

Programs are written in a high level language like C/C++, Java, Python, etc. in the case of C/C++ and some others, the compiler will convert the source code into binaries, CPU specific instructions that the target CPU can run directly. In the case of Java, the compiler convert the source codes into byte codes, an intermediary form of instructions that require to be interpreted by a Java Virtual Machine and convert them into machine specific instructions and execute them on the CPU. In the case of Python, the interpreter reads the source codes and follow the logics
