What’s inside an integrated chip?

I damaged a CD4093BE and instead of throwing it away I decided to satisfy my curiosity regarding its guts. I used Omaha Maker Group’s belt sander to grind away the top layer of material and it revealed a tiny chip embedded within. The slightly orangey color on the right side is where I sanded away a little too much of the tin protecting the copper legs. In the closeup view, you can just make out where filamentous wires must connect the legs to the chip.
