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.

Thread 'I need a concave mirror with a focal length length of 150 feet'

Thread 'I need a concave mirror with a focal length length of 150 feet'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
