The first integrated circuits

Who made the first integrated circuits? Recently, when I was searching the Web for that information, I came across a site that claimed that it depended upon what was meant by 'first' - first idea, first laboratory sample, first commercial production, first commercial success? What they did not seem to realise is that the answer also depends upon what you mean by 'integrated'.

In the pages linked off this one, I am going to try to answer this more general question. Some might argue that my definition of 'integration' is too loose, and that I have extended it to cover wider circuit packaging technologies. I don't really mind, I think the subject is an interesting one, about which there is some other information on the Web, but very few organised pages such as this.

The module may or may not be 'potted' to form a single pseudo-component. Click on the image for further details.
