This has nothing to do with Canon making their own chips. This is about their semiconductor photolithography business. These are types of equipment that the companies Tony names buy to make their IC's. Moreover, Canon has been in this business for a long time. As have Nikon. ASML has just been the leaders, but doesn't sell to Chinese fabs because of the sanctions. The big news here is Chinese fabs might be able to buy the equipment and start competing with Taiwanese companies like TSMC/UMC (the biggest foundries). In fact, a lot of BSI sensors are stacked chips that often than not come from a different wafer fabs.

Like the article says, there's no magic here, I doubt it's better than anything ASML has available.
