Hello everyone! We all have used IC`s in making projects or whatever,but i want to know that how LOGIC GATE circuits, and other connections, are made on little IC. It sounds impossible just like writing a name on rice ! Can anyone tell me how its done !

The key is a photographic process called Photolithography.
I hope the following links will help you to understand the whole process.
