Lattice Semiconductor supply chain risk
As of 2026-09-05, Lattice Semiconductor depends on 3 tracked suppliers headquartered in 2 countries (2 of them in Taiwan). 2 of those suppliers hold a monopoly or leader position in their own segment, led by TSMC and ASE Technology. The dataset records no companies downstream of Lattice Semiconductor: it sits at the demand end of the chain, so the risk here runs upstream only.
Data as of 2026-09-05 · suppliers are the curated key_supplier edges in the wafergraph dataset (researched or segment-inferred — see /methodology) · criticality is the graph-derived chokepoint score, 0–100
Dominant and single-source suppliers
- TSMC — leader in Pure-Play Foundry, Taiwan
- ASE Technology — leader in Outsourced Assembly & Test, Taiwan
A monopoly or leader supplier is the hardest to replace. These are the edges to watch first.
Suppliers by country
- Taiwan — 2 suppliers (67%)
- United States — 1 supplier (33%)
All 3 tracked suppliers
| Supplier | Segment | Position | Country | Criticality |
|---|---|---|---|---|
| TSMC | Pure-Play Foundry | leader | Taiwan | 81/100 |
| ASE Technology | Outsourced Assembly & Test | leader | Taiwan | 81/100 |
| Aldec, Inc. | EDA Software | challenger | United States | 58/100 |
Downstream exposure
- Criticality score: 0/100
- Companies downstream of Lattice Semiconductor: 0
