Edge/source evidence summary:

Prerequisite Type Confidence Evidence level Note Sources
Transistors (transistors) required 90% textbook The 1958 solid-circuit milestone integrated transistor-like active devices with other circuit elements on one semiconductor substrate.
Semiconductor Devices (semiconductor_devices) required 90% textbook The integrated-circuit node is scoped to semiconductor solid circuits fabricated on semiconductor material.
Photolithography (photolithography) commercial_or_scaling_dependency 64% expert_inference Photolithography and the planar process made integrated circuits manufacturable and scalable, but the 1958 Kilby solid-circuit demonstration means photolithography is not a universal hard prerequisite for the broad integrated-circuit concept.
Mass Production (mass_production) enabling 68% expert_inference Mass Production provides a capability that enables this technology without being the only possible path.
  • Mass production (Encyclopaedia Britannica, 2026, textbook) • Supports: edge
