Photoresists used for “old tech” (I-line, G-line, and KrF) are expected to surge due to the near-term chip supply constraints. KrF resists continue to find growth, especially as 3DNAND device production and layer count grows. ArF and ArFi both use similar polymer/solvent platforms that utilize an aqueous developer (0.263N tetramethyl Ammonium hydroxide – TMAH), and their demand is driven by multi-patterning applications.
In South Korea, Taiwan, and China, onshoring of photoresist production is a recurring theme, and domestic manufacturing of these materials is growing. Near-term issues impacting the photoresist market, as with other materials, are inflation, supply chain disruptions, and geopolitical events. All of these are contributing to price increases and product availability for the current year, and are expected to continue doing so into 2023.
It is also important to note that new suppliers surfacing in places like South Korea and China may lead to dynamic adjustments within the photoresist market landscape. These new suppliers are benefitting from government and chipmaker support within their respective countries.
