Fable: The Idea Which Improved Yields From 10% To 60%
Once upon a time the semiconductor industry struggled to produce transistors. Despite many incremental improvements and much hard work, the yield of working parts to duds was in the 10-20% region.
Then, in 1957, TI came up with a transistor which was the first to have both a diffused base and a diffused emitter.
Immediately, yields topped 60%, vastly increasing unit output and decreasing unit cost.
