Advanced Micro-Fabrication Equipment Inc. China

AMEC makes the giant machines that chipmakers and LED makers use to carve and coat silicon wafers.

AMEC is a Chinese maker of the big, expensive machines that turn silicon wafers into working chips. Its core product is an etching tool: a machine that uses carefully controlled plasma — an electrically charged gas — to carve microscopic patterns into a wafer, chip layer by chip layer. It also sells equipment for depositing thin films onto wafers and tools for making LED chips. Its customers are the fabs: the factories that mass-produce chips and LEDs, mostly in China.

Etch equipment
Etch equipment carves microscopic circuit patterns into silicon wafers for chips.

The business is a bet on a simple problem. Making a modern chip means stacking dozens of layers of microscopic structures, and each layer has to be carved and coated with incredible precision. If a machine is even slightly off, a whole batch of wafers can be ruined, so chipmakers buy tools only after long, brutal testing. That is why this industry is dominated by a handful of giants — Lam Research, Applied Materials, and Tokyo Electron — and why getting a new tool qualified at a fab is a slow, hard-won win. AMEC's edge is that it is a credible homegrown supplier in China, at a time when Beijing wants its chip industry to rely less on foreign equipment. That has helped it grow fast and win share inside Chinese fabs, including big memory and logic makers. The catch is that the most advanced machines depend on deeply complex supply chains, and export controls have made it harder to source some critical parts. The company has responded by pouring money into its own research and into local suppliers.


This is a research-heavy, cyclical business. Fabs order machines in waves, so revenue can swing sharply with chip industry spending, and AMEC must reinvest heavily to stay near the leading edge. Its long-run prize is straightforward: if Chinese chipmaking keeps expanding and AMEC keeps proving its tools can compete, it sells more machines into a market that is enormous and still mostly served by foreign rivals.
