How do semiconductors work?

logically, the same way as a relay. physically, get a physics degree. the prerequisite math is already too much for most people and is certainly not suitable for a 4chan post.

They conduct, sort of

A computer booting up is as physically causal as throwing a rock into water and watching it's waves propagate.
It's like utilizing gravity's pull on rainwater to drive hydroplants or irrigate fields, except it's electrilc potential instead of gravitational potential, and data processing instead of energy or food generation.

When you sit in a train on a sunny day in a country that utilizes solar energy and you feel the warmth of sunlight on your skin: It's the same energy that's moving you and the train.
A computer doesn't "calculate" 2+2=4, it loads 2 and 2 into "loading bays" (CPU registers) and "smashes" them together, and logic dicates the result must be 4, and it just passes that to you.
How fast it can load this data and smash them together and give that back to you, is basically how fast a processor is.

It's not magic, it's about making a giant maze that actually has logic and sense underneath it all.

The difficulty most people have with computers is that it's actually all dead simple, but your chaining tens of thousands of dead simple processes together to make something complex, and you first need to realize that.
Rocket science is actually complex in that regard, same with "real" maths, I like programming because most of the time it's a lot of "baby maths."
Also, your dealing with a real physical system with bounds; maths has the tendency to want to do things "for infinity."

Also, you should try to understand binary representation of quantity and appreciate how well that translates into electric on/off states.

A byte is basically eight electrical signals, that each can be on or off.
2^8 = 256 possible switch states, from all channels off to all channels on, and everything in-between.

Now lay down these wires between two houses (IRL: At least 8+1 signal and ground lines).
Sync your clocks, and send/read the signals every minute.
Boom.
You now have 60 bytes/minute communication system.

>You now have 60 bytes/minute communication system.
Eh, hour.
Then we can all agree that 0x30, which is 0b00110000, can be the binary representation for the number '0' and 0x40 is the capital letter 'A', and then you can call this system ASCII and now you have an agreed set of what each of these switch states mean.

That's it.
That's really all there is to it.

they must have really tiny hands to be able to make this

And that's going to be our modern-day morse-code.
(And at least you only need to really remember those two instead of an arbitrary morse code.)

You need to read a book/watch a video on it.
But the very simplified version is as follows:
Any and every material allow electrical charges to move on them.
But some will allow an easy flow (that's a conductor), and some won't allow an easy flow (that's an isolator. You would need a very high voltage, or a shitload of electrons, to make it conductive).
Semiconductors are material that usually don't allow a free flow of electrons, but will kinda allow ot to accumulate on it's border.

The simplest way to use it is to make a diode. It's like a wire, but will only allow the current to flow in one direction, not the other.
Very roughly, a diode is a stack of two semiconductors with different polarity (polarity is more or less "does it likes receiving or giving electrons").
Such a stack, when the electricity flows in the correct direction, will accumulate charges on the shared border, and, because the materials are carefully selected, the charge will be able to "jump" from one material to the other, allowing flow and thus conducting.
When the electricity flows in the other direction, the charge accumulate on the opposite sides of the junction. Meaning the electrons are far too distant to "jump". The electricity don't flow, the component isn't conducting.

Applying the same principles, by carefully stacking 3 layers with special properties, you can control if the charges travel from one side to the other by applying a charge on the "third side". It's more or less an electrically controlled switch, and it's called, a transistor.

don't think about it too hard or the plane won't be able to fly anymore

They don't. It's just enslaved Demons:

Instead of just ON or OFF you can say ON, KINDA ON and OFF.

Okay! Imagine a semiconductor is like a gatekeeper for electricity. It can let electricity pass through or block it, kind of like a light switch.

Most of the time, the material (like silicon) doesn’t let electricity through easily — it's like a closed gate. But when we add tiny special bits called "dopants", or when we give it a tiny push of energy (like from a battery), the gate opens — and electricity can flow!

This on-and-off control is what makes semiconductors so amazing. They’re used to make computer chips, phones, and even video game consoles work, by turning little electric signals on and off really fast — kind of like tiny light switches doing a super-fast dance inside your device!

So in simple terms:
Semiconductors are materials that can control electricity — sometimes letting it flow, sometimes stopping it — which helps our electronics think and work!
