Semiconductor Supply Chain Stocks
762 companies mapped with bottleneck scores, moat analysis, and supply chain positions. Find the monopolies and oligopolies that power the chip industry.
The semiconductor supply chain is one of the most concentrated industries in the world. A handful of companies hold monopoly or oligopoly positions in critical steps — from EUV lithography (ASML, the only maker) to advanced packaging (AMKR, TSM) to specialty chemicals (ENTG). When demand surges, these bottleneck stocks have pricing power that translates directly to stock performance.
Our Bottleneck Score (1-10) measures how irreplaceable a company is. A score of 10 means there's literally no alternative — if they stop, the industry stops.

Foundry — Companies that manufacture chips (TSM, INTC, GFS). The most capital-intensive step.
Chip Design — Companies that design but don't manufacture (NVDA, AMD, QCOM). Rely on foundries.
Equipment — Companies that make the machines foundries use (ASML, AMAT, LRCX, KLAC). Extreme bottleneck.
Materials — Companies that supply chemicals, gases, and substrates (ENTG, AXTI). Often sole-source.
Packaging — Companies that assemble and package chips (AMKR, ASX). Growing importance with chiplets.
EDA/IP — Companies that make chip design software (CDNS, SNPS, ARM). High switching costs.
