| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Photolithography (photolithography) | common_dependency | 72% | expert_inference | Photoresist chemistry is tightly coupled to semiconductor photolithography, but photolithography is the application context rather than a chemical hard prerequisite. |
|
| Advanced Chemistry (advanced_chemistry) | enabling | 68% | expert_inference | Advanced Chemistry provides a capability that enables this technology without being the only possible path. |
