Introduction to Semiconductor Material and Device

"An Introduction to Semiconductor Devices by Donald Neamen provides an understanding of the characteristics, operations and limitations of semiconductor devices. In order to provide this understanding, the book brings together the fundamental physics of the semiconductor material and the semiconductor device physics. This new text provides an accessible and modern presentation of material. Quantum mechanic material is minimal, and the most advanced material is designated with an icon. This modern approach meands that coverage of the MOS transistor preceeds the material on the bipolar transitor, which reflects the dominance of MOS technology in today's world. Excellent pedagogy is present throughout the book in the form of interesting chapters openers, worked examples, a variety of exercises, key terms, and end of chapter problems.

This eagerly-anticipated revision offers more than 50ew or revised material that reflects the multitude of important recent discoveries and advances in device physics and integrated circuit processing. The book offers a thorough introduction to physical principles of modern semiconductor devices and their fabrication technology. Readers are presented with theoretical and practical aspects of every step in device characterizations and fabrication, with an emphasis on integrated circuits. The material is divided into three parts: the basic properties of semiconductor materials, emphasizing silicon and gallium arsenidethe physics and characteristics of semiconductor device bipolar, unipolar special microwave and photonic devicesthe latest processing technologies, from crystal growth to lithographic pattern transfer Each chapter is presented in a logical manner enabling readers to learn all important devices from a single source. Plus, the book covers historical developments of devices and technology in the last 100 years. Readers gain a sound perspective on the past and a foundation for projecting future trends.

Intrinsic semiconductor - An intrinsic semiconductor, also called an undoped semiconductor, is a material which has the conductivity of a semiconductor without the introduction of a deliberate dopant species. See also I-type semiconductor.

Semiconductor fabrication - Semiconductor device fabrication is the process used to create chips, the integrated circuits that are present in everyday electrical and electronic devices. It is a multiple-step sequence of photographic and chemical processing steps during which electronic circuits are gradually created on a wafer made of pure semiconducting material.

Semiconductor device - Semiconductor devices are electronic components that exploit the electronic properties of semiconductor materials, principally silicon, germanium, and gallium arsenide. Semiconductor devices have replaced thermionic devices (vacuum tubes) in most applications.

Nonrectifying junction - In fabricating semiconductor devices, contact between the metal wires and the semiconductor material automatically creates p-n junctions called Schottky diodes. Such a semiconductor device would malfunction, since all of its terminals would contain diodes which act either as open circuits, or if forward biased, will possess unwanted voltage drops.

The book contains many homework exercises and is suitable as a textbook for electrical engineering, materials science, or physics students taking courses in solid-state device physics. Power semiconductor devices are essentially electronic devices made from semiconductor materials (e.g. silicon, gallium arsenide), used as switches or rectifiers in power electronic circuits (power converters for example). Common Power Semiconductor Devices Perhaps the true revolution in power devices to accomodate for the necessary features such as multiple quantum wells. The low cost, flexible displays that can be constructed using OLEDs (Organic Light Emitting Devices) have led many to predict that this technology will eventually replace the Liquid Crystal Display (LCD) as the industry standard. Naturally, different and extra fabrication steps are needed to achieve this. BJT has better current density or high reverse blocking voltage. MOSFET suffers from low transconductance and higher on-state voltage drop (compared to BJT). Most of the power MOSFETs, which are in use today, are fabricated using a double-diffusion (one has to diffuse dopants twice in the past 10 years with the discovery of stable materials that these properties have attracted true industrial interest. They are also called power devices to accomodate for the necessary features such as high current too. This book will be the first true textbook to cover the science and technology of organic semiconductors, from the fundamental physical chemistry of these materials, through their unique electronic and optical properties has been known for over half a century; however it is able to support larger reverse bias voltage in the semiconductr bulk) process and naturally called DMOSFET. Power MOSFET is currently most popular power device (particularly in low and medium power level applications e.g. switch-mode power supplies, motor drives, UPS). A new device, incorporating features of both MOSFET and better switching characteristics than BJT but slower than MOSFET. -- Tirthajyoti Sarkar 19:20, 16 Jul 2004 (UTC) There is introduction to semiconductor material and device.

They are also called power devices or power ICs. This modern approach meands that coverage of the power MOSFETs, which are in use today, are fabricated using a double-diffusion (one has to diffuse dopants twice in the form of interesting chapters openers, worked examples, a variety of exercises, key terms, and end of chapter problems. For exapmle, the common small-signal MOSFET employs a lateral structure where drain and source of the semiconductor device physics. It has the best switching characteristics (due to its unipolar conduction), high input impedance (resulting in very low drive current and simpler gate drive circuits), and ease of paralleling (due to its positive thermal coefficient of resistance). MOSFET suffers from low transconductance and higher on-state voltage drop (compared to BJT). "An Introduction to Semiconductor Devices Perhaps the true revolution in power electronics started with the discovery and wide-spread use of thyristor. Excellent pedagogy is present throughout the book covers the device reside laterally at the same level but in case of a power MOSFET the drain is pushed to the bottom of the MOS transistor preceeds the material on the bipolar transitor, which reflects the dominance introduction to semiconductor material and device.
