Titelbeschreibung

An accessible guide to how semiconductor electronics work and how they are manufactured, for professionals and interested readers with no electronics engineering background Semiconductor Basics is an accessible guide to how semiconductors work. It is written for readers without an electronic engineering background. Semiconductors are the basis for almost all modern electronic devices. The author—an expert on the topic—explores the fundamental concepts of what a semiconductor is, the different types in use, and how they are different from conductors and insulators. The book has a large number of helpful and illustrative drawings, photos, and figures. The author uses only simple arithmetic to help understand the device operation and applications. The book reviews the key devices that can be constructed using semiconductor materials such as diodes and transistors and all the large electronic systems based on these two component such as computers, memories, LCDs and related technology like Lasers LEDs and infrared detectors. The text also explores integrated circuits and explains how they are fabricated. The author concludes with some projections about what can be expected in the future. This important book: <ul> <li>Offers an accessible guide to semiconductors using qualitative explanations and analogies, with minimal mathematics and equations</li> <li>Presents the material in a well-structured and logical format</li> <li>Explores topics from device physics fundamentals to transistor formation and fabrication and the operation of the circuits to build electronic devices and systems</li> <li>Includes information on practical applications of p-n junctions, transistors, and integrated circuits to link theory and practice </li> </ul> Written for anyone interested in the technology, working in semiconductor labs or in the semiconductor industry, Semiconductor Basics offers clear explanations about how semiconductors work and its manufacturing process.

Rezension

Semiconductor Basics is an excellent beginner's guide on the average semiconductors used in many projects, explaining the usage in detail and other important data one must know. It's a perfect way to get a good selection of many different types. Creating a perfect guide for those in the engineering career field. I found this book's resource and learning curve to be a bit easier to digest and use. It is much better than many books I've looked into and read on the process and fundamentals. I really want to get more ideas on many of the electrical pieces that are there to bring electrical energy through a product, after reading this! It's a great starter and part of a beautiful connection that makes devices run. So I can't say there isn't anything wrong with owning this book, especially for an amateur or professional engineer or electrician. When going from front to back, the book is completely full of details and important people who discovered and created data on such parts that are taught inside this book on semiconductors. The book is very easy to read and has plenty of black and white illustrations and colored images to help provide a clear view of different topics being explained. I honestly enjoyed getting a bit of a physics, mechanical, engineering recap by learning about the atom, the design, many well-known people who brought these discoveries to light and so much other information. Lastly, this book is a nice guide. It's very helpful and a great beginner guide. I would recommend this book for those interested in electronics whether it be personal projects, large or small, and company-related. This is an excellent guide and book! - TECH Fashion Trends
