History of Semiconductor Engineering
28 Jun 2006 | | Contributor(s):: Bo Lojek
When basic researchers started working on semiconductors during the late nineteen thirties and on integrated circuits at the end of the nineteen fifties, they did not know that their work would change the lives of future generations. Very few people at that time recognized the significance of...
