Semiconductors Companies

The semiconductor sector designs, manufactures, and sells the chips powering every computer, smartphone, car, and AI system on the planet. This guide covers the industry structure, revenue models, key metrics, and the major companies driving the $600B+ market.

Semiconductors are the foundational layer of the modern economy. Every smartphone, data centre server, electric vehicle, and AI accelerator runs on chips — and the companies that design and manufacture them occupy some of the most valuable positions in global business.

The global semiconductor market exceeded $600 billion in revenue in 2024, and is projected to cross $1 trillion by 2030, driven by surging demand for AI infrastructure, automotive electronics, and advanced mobile compute.

How the Semiconductor Industry Is Structured

The industry splits into several distinct layers, each with different economics:

1. Fabless Designers

Fabless companies design chips but outsource all manufacturing to foundries. This model produces the highest gross margins in the sector — typically 50–75% — because design IP carries almost no variable cost once developed.

Key fabless companies covered on Visuwire: NVIDIA, AMD, Qualcomm, Broadcom, Marvell, ARM Holdings.

2. Integrated Device Manufacturers (IDMs)

IDMs both design and manufacture their own chips. They carry higher capital expenditure burdens — fabs cost $10–$20 billion each — but capture more of the value chain. Intel is the canonical IDM, though it has struggled to maintain manufacturing leadership.

Key IDMs covered: Intel, Texas Instruments, Analog Devices, Microchip Technology.

3. Pure-Play Foundries

Foundries manufacture chips designed by fabless customers. They compete on process node leadership, yield rates, and capacity. TSMC manufactures chips for Apple, NVIDIA, AMD, Qualcomm, and hundreds of other customers — making it the single most critical company in the semiconductor supply chain.

Key foundries covered: TSMC.

4. Equipment Makers

Semiconductor equipment companies sell the lithography machines, etch tools, deposition systems, and inspection equipment that fabs need to produce chips. Without ASML’s extreme ultraviolet (EUV) lithography machines, the most advanced nodes below 7nm cannot be manufactured anywhere on Earth.

Key equipment companies covered: ASML, Applied Materials, Lam Research, KLA Corporation.

5. Memory Manufacturers

Memory is a commodity cycle business — DRAM and NAND flash prices swing dramatically with supply and demand. Margins collapse during downturns and surge during shortages. Micron is the primary US-listed memory manufacturer.

Key memory companies covered: Micron.

The Fabless Advantage

The fabless model has produced the best returns in the sector. By externalising manufacturing capex to TSMC and Samsung, companies like NVIDIA and Qualcomm can generate operating leverage that IDMs cannot match — R&D and SG&A costs are relatively fixed while revenue scales with chip volumes shipped globally.

NVIDIA’s gross margin expanded from ~65% in 2022 to over 74% in FY2025, driven by the premium pricing power of its H100 and H200 data centre GPUs. Fabless economics at scale are exceptional.

Key Metrics for Analysing Semiconductor Companies

Gross Margin

Gross margin is the primary indicator of a semiconductor company’s competitive position. Fabless chip designers with strong IP command 60–75%+ gross margins. If gross margins are falling, it signals pricing pressure, commoditisation, or manufacturing cost increases.

Revenue by End Market

Most semiconductor companies break revenue into end markets: data centre, PC/client, mobile, automotive, industrial, and IoT. The mix matters enormously — data centre and AI workloads carry the highest ASPs (average selling prices) and fastest growth rates.

Book-to-Bill Ratio

A ratio above 1.0 means incoming orders exceed shipments — demand is outpacing supply. Below 1.0 signals a demand slowdown. This is a leading indicator of quarterly revenue trends.

Inventory Levels

High chip inventory in the supply chain (at OEMs or distributors) precedes revenue downturns, as customers draw down existing stock before placing new orders. Watch days inventory outstanding (DIO) across the supply chain.

Capital Expenditure

For IDMs and foundries, capex as a percentage of revenue indicates investment intensity. TSMC’s annual capex often exceeds $30 billion — that capital intensity is the moat. For fabless companies, capex is minimal (typically 1–3% of revenue).

The AI Infrastructure Buildout

The AI boom that began in 2023 fundamentally reshaped semiconductor demand. Training large language models requires tens of thousands of high-performance GPUs. Inference — running models at scale — requires even more.

NVIDIA captured the AI infrastructure wave early with its CUDA software ecosystem, which created a switching cost that pure hardware competitors cannot easily overcome. AMD has narrowed the gap with its MI300X and MI325X accelerators, but CUDA’s installed base remains NVIDIA’s deepest moat.

The AI chip market is expected to grow from ~$50 billion in 2024 to over $300 billion by 2030.

Key comparisons for AI chip investors:

The Equipment Chokepoint

Semiconductor equipment is arguably the most strategically important sub-sector. ASML holds a global monopoly on EUV lithography — there is no alternative supplier. Every leading-edge chip (iPhone processors, NVIDIA GPUs, AMD CPUs) requires ASML machines to manufacture at 7nm and below.

This monopoly position gives ASML pricing power that translates into 50%+ gross margins and return on invested capital that rivals even the best fabless designers.

Applied Materials, Lam Research, and KLA Corporation similarly hold dominant positions in etch, deposition, and inspection — the other critical steps in chip fabrication.

Geopolitical Risk

No sector carries more geopolitical risk than semiconductors. The US-China chip war has reshaped the industry:

  • US export controls (2022–2024) blocked advanced AI chips and equipment exports to China, directly impacting NVIDIA, AMD, and ASML revenues
  • The CHIPS Act committed $52 billion in US subsidies to reshore semiconductor manufacturing — benefiting TSMC Arizona, Intel, Samsung, and Micron
  • Taiwan concentration risk — over 90% of the world’s most advanced chips are manufactured in Taiwan by TSMC. Any disruption to Taiwan would be catastrophic for global electronics supply

China now accounts for roughly 25–30% of global semiconductor demand but is systematically cut off from the most advanced chips and manufacturing equipment.

Semiconductor Cycle Dynamics

The semiconductor industry is famously cyclical. Revenue typically follows a 3–4 year boom-bust pattern driven by inventory accumulation and drawdown.

The 2022–2023 downturn was one of the sharpest on record — PC and smartphone demand collapsed post-COVID, leaving the supply chain with massive excess inventory. By mid-2024, most segments had normalised, with AI infrastructure demand masking ongoing weakness in consumer electronics.

Leading indicators of the next downturn:

  1. Rising channel inventory at major OEMs
  2. Falling average selling prices in DRAM/NAND
  3. Book-to-bill ratios falling below 1.0 for multiple quarters
  4. Customer order cancellations at foundries
