They spend about 1 billion to 4 billion every second year just to expand and upgrade their fabs.
This kind of costs can't be covered by camera sensors along, they pretty much have to sell sensors to smartphones and factory robots and whatnot to make back that kind of money.
In that perspective, one can start to understand why Canon insist on using old 500nm technology and refuse to upgrade from that because it's a multi billion dollar adventure that can go horribly wrong if you don't invest smart and have good products.
