I mean 3B is a large number ,how to design and even count them?
Well…I am really like I am five.

The chip is made up of substrucutres that are made of transistors. These structures can be put together like lego blocks to build bigger structures, which can again be combined into larger structures, and so on
Once the smallest structure is designed (which may only be a few tranaistors) the designers can copy and paste it to create bigger structures. Once those are designed, they can again be copy and pasted and reused. Nobody is literally placing 3 billion individual transistors
Once the design is complete, it gets put into a machine that will read it and project it onto the chip. This is the opposite of how a home media projector would work, instead of making the image larger, it makes the image smaller. Much smaller. It focuses the full chip design down onto a small piece of silicon, and the light etches out the microscopic transistors
