I hate to be a sour puss, but being able to manufacture the whole 28nm semiconductor cycle, does not allow one to conclude that China, all of a sudden, will become the biggest semiconductor supplier globally.
I believe China will necessarily become the largest supplier, for the simple fact that China owns the market for semiconductors. It, arguably, uses somewhere near 60% of the global production of semiconductos, therefore, it is just a matter of manufacturing the thing in order to become THE largest world supplier.
However, there is an enormous distance from knowing how to make the thing (manufacturing a working prototype) to becoming the biggest semiconductor supplier globally.
It will, no doubt, happen. But will probably take another five to ten years to get there.
As @kraumeister says:
"Once equipment and materials are ready, you will start seeing a steady and sustained decline of all foreign semiconductor equipment & materials. This will continue for years as China's equipment quality improves until market share is dominated or even monopolized within China by China companies, mark my words."
I fully agree with him, but it will take years.
My two cents.
