First integrated circuits were thermionic

摘要

I would like to offer a correction to the title of the article in the November 2008 issue of Siltcon Chip, "50 Years Of The Integrated Circuit". If the author Ross Tester had more completely researched his topic he would have discovered that the first integrated circuits were not invented in 1958 but were in fact a German invention dating back to the mid 1920's by the well-known company Loewe. They were not based on silicon or germanium technology but were composed of several thermionic valves (tubes to the North Americans) integrated with various resistors and capacitors in a single package.
