# Photoresists: Feedstocks

How a naphtha shock reached the world's chip lines

How a naphtha shock reached the world's chip lines What this tab covers What it is made from and what it feeds: the raw materials and energy per tonne with their share of cost (linked to the commodity table), who is low-cost and why, and the chemicals made from it.

Resists are made from specialty monomers, photoacid generators and solvents, all petrochemical. Raw material cost is a small part of price; formulation know-how, ultra-clean manufacturing and qualification decide competitiveness.

#### Inputs per tonne

| Input | Quantity per tonne | Role | Share of cost | Source |
|---|---|---|---|---|
| [Oil Crude oil](https://www.materialinsights.org/energy/crude_oil/) | not published | polymer backbone | small (indicative) | TrendForce (Apr 2026); indicative |
| **Solvents (PGMEA, ethyl lactate, cyclohexanone)** | most of resist mass (indicative) | carrier for spin coating | small (indicative) | Indicative |
| [F Fluorspar](https://www.materialinsights.org/commodities/fluorspar/) | small (indicative) | acid generation, coating quality | not published | Indicative |
| [Sn Tin](https://www.materialinsights.org/commodities/tin/) | not published | EUV absorber | not published | Indicative |

#### Who is low-cost, and why

Not a cost curve market. Prices reflect qualification, defect performance and supply security; Japanese suppliers command premiums at advanced nodes.
