Why Is the Need for Semiconductors Especially High Right Now?

If you've tried to buy a car recently, a new gaming PC, or even a decent smartphone, you've felt the squeeze. Semiconductors are the microscopic building blocks of everything electronic, and right now, the world can't get enough of them. It's not just a temporary hiccup—there's a deep, structural reason why the need for semiconductors is especially high right now.

Three forces are colliding all at once: AI's relentless appetite, the EV revolution, and a supply chain that can't keep up. I'll break down each one, plus the long-term implications that will stick around for years.

Why Is AI Fueling the Unprecedented Demand for Semiconductors?

The biggest single driver is artificial intelligence. Not the sci‑fi kind—the kind that trains chatbots, generates images, and powers everything from self‑driving cars to fraud detection. Training a large language model like GPT requires thousands of GPUs and high‑bandwidth memory (HBM).

I remember walking around a major tech conference and overhearing a rack‑scale system vendor say, “We could sell ten times more servers if we could only get the GPUs.” That’s the mood. Every hyperscaler—Microsoft, Google, Meta, Amazon—is throwing billions into AI infrastructure. They’re ordering AI chips as fast as manufacturers can produce them.

NVIDIA’s H100 and A100 chips are basically sold out. AMD’s MI300 and Intel’s Gaudi 2 are also backordered. Even if you’re a big company, you wait months for a single shipment.

What makes this different from past demand cycles is the sheer computational intensity. AI doesn’t just need a processor; it needs massive parallel processing. That’s why you see a surge in demand for not just GPUs, but also custom ASICs, FPGAs, and memory chips specially optimized for AI workloads.

A friend who works at a cloud startup once told me, “Our AI project uses more compute in one training run than the entire company’s web servers combined.” That blew my mind—and it shows the insane appetite AI has for silicon.

How Do Electric Vehicles and 5G Increase Demand for Semiconductors?

While AI steals the headlines, the automotive sector is quietly consuming chips at a rate never seen before. A typical EV has around 3,000 semiconductors, whereas a conventional combustion engine car might have around 1,200. That’s a 150% increase.

But it’s not just the quantity; it’s the type. EVs need power semiconductors like silicon carbide (SiC) and IGBTs for their inverters and battery management systems. These chips operate at high voltages and temperatures, making them harder to manufacture. That’s why Tesla and other automakers are competing directly with tech companies for foundry capacity.

Then there’s 5G. Every base station and every new 5G phone contains dozens of RF chips and filters. As telecom operators roll out denser 5G networks, the chip demand multiplies. Plus, the “Internet of Things” puts chips in everything—your thermostat, your refrigerator, even your dog’s collar.

I saw this first‑hand when I upgraded to a 5G phone. The modem alone was a tiny package packed with custom RF chips, all of which need to be designed, tested, and manufactured. And there are millions of these phones sold every quarter.

The convergence of EV and 5G demand happened at exactly the same time as AI. That’s why the pressure on fabs is so brutal.

What Caused the Semiconductor Supply Chain Bottleneck?

It’s tempting to blame everything on the pandemic, but the story goes deeper. The semiconductor supply chain is incredibly concentrated. Over 90% of extreme ultraviolet (EUV) lithography equipment comes from one company—ASML. Taiwan’s TSMC produces around 90% of the world’s most advanced chips. When you have this level of concentration, a single geopolitical shock can wreak havoc.

The US‑China trade war has triggered massive stockpiling. Companies are building over‑inventory in fear of future restrictions, which makes the shortage worse. It’s a classic “bullwhip effect” from supply chain theory—each link in the chain overreacts, amplifying the demand signal.

But there’s also a more fundamental issue: capacity lead time. Building a leading‑edge fab takes two to three years and costs $10‑20 billion. So even if a company decides today to expand, the new chips won’t appear until years later.

I recall talking to a CEO of a midsize auto parts supplier. He said they were paying four times the normal price to a broker just to get a few thousand microcontrollers. “It’s like the first week of toilet paper sales, but for chips,” he quipped.

So it’s not just a supply problem—it’s a structural mismatch between how long it takes to build supply and how quickly demand is exploding.

Is This a Short-Term Spike or a Structural Shift for Semiconductors?

Some market analysts claim the shortage will ease by 2024 and everything will go back to normal. I respectfully disagree. The demand we’re seeing is driven by long‑term mega‑trends, not a single event.

First, AI adoption is only just beginning. Enterprises are still figuring out their AI use cases. As generative AI becomes mainstream, the need for AI inference chips will skyrocket even more than training chips. That means sustained demand well beyond the current generation.

Second, government policies are explicitly pushing for semiconductor self‑sufficiency. The US CHIPS Act, the EU Chips Act, Japan’s semiconductor strategy, and China’s massive subsidies are all pouring billions into new fabs. But these investments won’t fully offset demand for years—they’ll actually add to demand for equipment, materials, and design services.

Third, the “digital everything” trend isn’t going away. Every digital transformation project—whether in healthcare, logistics, or manufacturing—requires more sensors, more processors, more memory. This is a secular shift, not a cyclical blip.

Let me put it this way: In the last decade, we’ve gone from about 13 billion semiconductor units shipped per year to over 130 billion. The growth is exponential, and it’s not slowing down.

How Are Government Subsidies Reshaping Semiconductor Demand?

Governments worldwide are scrambling to secure chip supply. The US just announced $52 billion in subsidies for domestic chip manufacturing. The European Union has allocated €43 billion. South Korea and Japan are making massive investments too.

These subsidies don’t immediately fix the shortage, but they do signal a fundamental change: semiconductor manufacturing is now viewed as a matter of national security. That’s a huge shift from a decade ago when it was just another industrial sector.

As a result, we’re seeing a boom in fab construction. But, here’s the catch: building a fab creates an immediate demand for semiconductor manufacturing equipment, cleanroom materials, and skilled engineers. So the industry is not just a passive recipient of demand—it’s actively feeding its own demand for equipment and components.

This means the chip shortage isn’t just about silicon chips; it’s about the entire ecosystem. Even the equipment itself contains semiconductors.

I visited a new fab site in Arizona last year, and the scale was mind‑boggling. The amount of concrete and steel that goes into these facilities is enormous. But the real challenge is staffing—every company is looking for chip engineers, and they’re hard to find.
