Product Description

How does a piece of silicon become a machine that calculates, remembers, and powers artificial intelligence? The answer begins with electrons. This illustrated introduction follows electrons through the structures that make modern electronics possible. Starting with silicon atoms and energy bands, it explains how doping changes a material, how a transistor controls current, and how connected switches perform calculations. It then explores how chips store information, emit light, and turn sunlight into electricity. The journey continues inside the semiconductor factory. Discover how silicon wafers are made, how light defines tiny patterns, and how deposition, etching, and metal wiring build working circuits. Learn why some chips fail, how packaging connects them to electronic devices, and why chiplets and high-bandwidth memory have become essential to AI hardware. Inside, you will explore: • Energy bands, doping, and pn junctions through the behavior of electrons. • MOSFETs, logic circuits, addition, and signal amplification. • The physical principles behind LEDs, solar cells, DRAM, and flash memory. • Wafer manufacturing, lithography, deposition, etching, testing, and packaging. • Transistor scaling, chiplets, and the partnership between AI processors and HBM. Clear diagrams make invisible processes easier to picture. Links to interactive simulations accompany every chapter, letting you change conditions and see the principles in action. Written by physicist and engineer Andy Kim, this book is for curious readers who want to understand what happens inside a chip. No prior knowledge of semiconductor physics is required. Each chapter builds on the last, connecting the motion of electrons to the technologies we use every day.
