The purpose of this book is to understand the entire process from design to completion of semiconductor. In the field of semiconductor development, not only process and device development, but there are many different fields such as digital & analog design, signal processing, materials, and verification technology.This book is expressed in different approaches with various examples so that the reader is able to understand basic concept in semiconductor though you are not engineering majors. In particular, the book explains how the system semiconductor design methodology is different from other engineering technologies and is changing the world in a new way.Even though you work in the semiconductor field for a long time, it is not easy to solve the puzzle in order to understand the entire semiconductor unless you understand the interconnection between design, process, manufacturing, and marketing. This book is structured as one scenario to put the pieces of the puzzle together while looking at the technology and the market as a whole. In addition, the book shows the structure of electronic products in daily life and role of semiconductor devices in system that act as brains.By reading this book, you will increase your understanding of IT devices and will be able to strengthen knowledge muscle of semiconductor as well as industry.
