Modern Transistors

The semiconductor industry is a fundamental building block of the new economy, there is no area of modern life untouched by the progress of nanoelectronics. The electronic chip is becoming an ever-increasing portion of system solutions, starting initially from less than 5% in the 1970 microcomputer era, to more than 60% of the final cost of a mobile telephone, 50% of the price of a personal computer (representing nearly 100% of the functionalities) and 30% of the price of a monitor in the early 2000's.

In the last 100 years, the world has undergone a tremendous revolution made possible by advances in modern electronics. Electronic devices—which manipulate electrons or their associated fields in fundamental ways to produce a useful effect—have provided us with ubiquitous, massive computational power; allow us to communicate nearly instantly with loved ones across the globe; can flawlessly record, safeguard, and display information; and provide us with tremendously precise control of manufacturing devices and medical instruments. They are fundamental to our global economy, improve our lives immeasurably, and underlie virtually every aspect of modern life. Yet very few of us have any idea of how electronic devices actually work.
