Herbert A. Waggener On The Bell Lap, Walking Among Giants

I joined Bell Labs in 1961, wanting to prove that I could compete and contribute to the progress of silicon semiconductor technology, in the midst of an amazing group of giants. After some meandering about, I was successful in a small way. Among other things, I invented alcoholic alkaline anisotropic etches for forming isolation slots, electrochemically controlled thinning for forming very thin silicon structures, and applied them to making high speed bipolar integrated circuits. My group and I were drafted into a massive technology development program to help develop a very advanced double level tungsten gate MOS memory technology. My group and I made significant contributionsd to the project before I left to join the Teletype Corporation in Skokie Illinois. I left some small footprints on the sands of time while at Bell Labs, but wanted to find a new venue for my efforts.
