: How are manufacturers able to manufacture really small cpu transistors?
In: Technology
Lithography is the term your seeing over and over here. But it’s not as simple as everyone is making it sound, it’s a really amazing process to generate appropriately small wavelengths of light.
Eli5 version is, imagine light is like a marker, you can only make lines as thin as your marker tip, in order to make a smaller marker tip they use one marker (a laser) to make a new marker that’s smaller, by shooting a laser into a perfectly round ball of tin, that tin then emits new light if a smaller wavelength (aka smaller marker)
