This article reviews the invention of the electronic valve (lightbulb, audion, diode, triode and magnetron) and their modern counterpart (diode sputter ion pump and the diode parallel-plate RIE reactor), in the period from the 1870’s to the 2016. Emphasis is given to the human nature of discovery, invention and patent filing and litigation, along with the fundamental physics and electrical engineering concepts applied within the inventions. The malfunction (mode jumps and instabilities) of the electronic valves are examined using an electrical engineering approach. In the absent of such an approach for the diode sputter ion pump “Argon instability”, coupled ordinary differential equations have been used to the mimic the dynamics of the heterogeneous gas burial / release process. Lastly, heterogeneous chemical mode jumps in the metal-organic reactive etch process of GaAs semiconductor material has also been considered.
