[Hello, Chips! Chapter 15] Why is a Semiconductor Half a Conductor? Device structure basics and GAA with extreme difficulty!

Semiconductors, why half a conductor? (00:58)
It's called semi-conductor because it's only half of a conductor. Is it because it only conducts half the electricity? No No!
Sometimes a conductor, sometimes a semi-conductor.
How is this possible? Let's start with the concept of transistor structure and GATE.

How Semiconductors Work, From FinFET to 3nm GAA (06:46)
As semiconductors become smaller, more problems that need to be solved arise, which are leakage currents.
Now various process technologies have been developed to block this leakage current!
We introduce in detail from FinFET to GAA.

Technology Competitiveness Will Become Power! Next-generation Foundry Technology GAA (08:48)
3nm GAA is a highly advanced technology that is called a revolution in semiconductor circuit technology.
What's more surprising is that Samsung Electronics is the only place where this technology is possible.
What is the significance of having GAA technology in the era of the Fourth Industrial Revolution?

Hello Chip's subject has finally moved on to the realm of electrical engineering.
