Book review number 114. Whenever people talk about investing in Korea these days, stocks come up, and semiconductors always seem to be part of that conversation. You hear a lot of talk that semiconductor stocks have already risen as high as they can go, but I've seen something similar happen before, so I kept wondering whether this was the start of another surge or a real peak. Then I found a semiconductor book that offers expert knowledge and helps you pick an investing direction, so I read it closely and want to share the experience.

"The Minimum Semiconductor Knowledge for Successful Investing" was written by Moonie Insight (무니 인사이트), an engineer with more than 15 years in the semiconductor field. You can find semiconductor books easily in any bookstore, but since this one was written by a long-time working engineer, I personally found it more trustworthy to read.

True to its title, the book covers really basic semiconductor content too. I was familiar with the word "semiconductor" but didn't actually know what it meant, so it helped me a lot personally.

## What is a semiconductor? Understanding it through a faucet analogy

The book compares a semiconductor to a faucet. Just as a faucet opens and closes the flow of water, a semiconductor can control the flow of electricity. That explanation was very easy to follow, and overall I liked how clear and easy to understand the expert's explanations were.

In reality, a semiconductor is technology for controlling the flow of electricity, and apparently the key is fitting more smaller, faster switches into a tighter space.

### What does a transistor do?

The switch inside a semiconductor is called a transistor. It's a kind of amplifier, a device that controls the passage so the large energy waiting on standby can flow.

For example, when electricity flows it's a 1, and when it stops it's a 0, and this simple choice is repeated hundreds of millions of times per second. Apparently Nvidia's latest GPU contains about 200 billion transistors.

## Semiconductor investing tips from the book

### Tip 1) More transistors, smaller, more efficient

More transistors doesn't automatically mean a better chip, but the book says one thing hasn't changed in 50 years: the companies that pack in more transistors, smaller and more efficiently, dominate the market. So what's the fastest way to gauge a chipmaker's technological competitiveness today? Whether it fits transistors onto a chip in greater numbers, at smaller sizes, and more efficiently!!

### Tip 2) Size is the measure of technology: the nanometer

Size is the measure of technology. The smaller it gets, the less electricity it uses, the faster it runs, and the more you can fit in. The number that shows how small a transistor is made is the nanometer, and that nanometer figure represents technological ability.

### The most expensive chip equipment: lithography machines and ASML

Making semiconductors takes all sorts of machines and technologies, but the one regarded as the most expensive is the lithography machine (노광 기계). It does the job of drawing the semiconductor circuits, and the only company in the world that makes this equipment is ASML, whose technology is, so far, irreplaceable.

### The three most important numbers in semiconductor economics

- Chip size
- Number of chips per wafer
- Yield

## Can you read it with zero semiconductor knowledge?

After reading "The Minimum Semiconductor Knowledge for Successful Investing," I feel I'll be able to broadly understand news about new processes or performance improvements. Even if you know nothing about semiconductors, I think you can pick things up in no time as you read.

The book explains everything in real detail, from the basic knowledge to the way of thinking you need for investing, so it helped me a lot personally. I liked that it let me understand how semiconductors work, follow their growth story, and above all gave me a technical foundation for predicting what comes next.
