# Survey the Competing 1962-1965 MOS Development Programs: RCA, Fairchild, GE, and Bell Labs

## 1. Why Multiple Independent Programs, Not One, Carried This Era Forward

Beyond RCA's shift register (Step 6) and Fairchild's static logic gate (Step 12), General Electric and Bell Labs (where Atalla and Kahng had originally built the first working device in Step 3) each ran their own experimental MOS programs through this period, approaching the same underlying surface-passivation and yield problems from somewhat different process angles, and the resulting cross-pollination of findings — sodium contamination identified at one lab, PSG fixes validated at another, static-logic feasibility proven at a third — moved faster collectively than any single lab's isolated effort could have. The program landscape, laid out directly:

## 2. Real Diagram: Which Specific Problem Each Program's Work Mapped Onto

Mapping each program against the specific problem it most directly advanced — rather than treating all four as redundant repetitions of the same work — shows a genuine division of labor across this series' own earlier steps, none of which any single lab could have completed alone on the timeline the industry actually achieved.

## 3. Which Specific Problem Each Program's Work Mapped Onto

This distributed-progress pattern is also why no single named inventor or lab fully owns experimental MOS's 1962-1965 story the way Hoerni's name attaches cleanly to the planar process or Kilby's and Noyce's names attach to the monolithic integrated circuit — it is, honestly, a multi-lab result, and the next and final step closes the series on that basis rather than crediting one program alone.
