This book is the first to give an authoritative and comprehensive account of the invention of Integrated Circuits (ICs) from an insider who had participated and contributed from the beginning of their invention and advancement to the Ultra Large Scale ICs (ULSICs) of today. It reads like a mystery novel to engross the reader, but it is not based on fiction; it gives documented facts of the invention of ICs, analyzes the patents, and highlights additional details and clarifications of their history.
