AI Thread Summary
Logic gate circuits and connections are implemented on small integrated circuits (ICs) through a process known as photolithography, which utilizes light to transfer patterns onto a substrate. This technique allows for the miniaturization of electronic components, making complex circuits feasible on tiny chips. The discussion highlights the seemingly impossible nature of fitting intricate circuits into small spaces, akin to writing on rice. Additional resources, including links to educational materials on integrated circuits and photolithography, are provided for further understanding. The conversation emphasizes the significance of these manufacturing processes in modern electronics.

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.

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
