Semiconductor fabrication plant

And so there are two types of firms in the semiconductor industry that actually uses EUV lithography.

One is Advanced Logic, TSMC, and Intel, and Samsung, Foundry.

The other is DRAM.

And so you are really at the highest end of sophistication when it comes to manufacturing.

And then people focus on making the manufacturing very well.

So when TSMC decide the foundry model, Unfortunately, during the time in 1986, the Foundry model wasn't really very sexy for most people.

I believe when TSMC wanted to do that, they tried to find an investor.

They could not find the right investor.

And in fact, that is why it became so successful today.

Yeah.

Another thing I want to mention, which we did not know in the beginning, but there's a so-called kind of return on investment benefit from Foundry.

When I developed 0.18 Micro, it was in 1998, almost 30 years ago, 28 years ago.
