Wanlass and Sah: complementary MOS circuits

What changed

Digital logic gained a low-static-power circuit architecture that later became central to dense integrated electronics.

Scientific scope

The joint 1963 conference paper; Wanlass's patent, prior MOS transistor and later RCA production are separate.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. This is the joint 1963 conference paper. Wanlass’s patent, the earlier MOS transistor and RCA’s later production program are distinct contributions.
