Insulated gate bipolar transistor



Equivalent circuit for IGBT

The insulated gate bipolar transistor or IGBT is a three-terminal power semiconductor device primarily used as an electronic switch and in newer devices is noted for combining high efficiency and fast switching. It switches electric power in many modern appliances: electric cars, trains, variable speed refrigerators, air-conditioners and even stereo systems with switching amplifiers. Since it is designed to turn on an ....etc

artificial retina is developed for the disabled to people, so that they can retrieve their view. It was developed with the help of external camera (cameras) who worked as a stimulus from view of the brain through electrodes. The device has been used as a substitute for the cells in the retina of the eye. They have been formulated using large-scale integration third dimension, so that a person can receive the exact image of an object that is in front of them.

The artificial retinas function using thin-film transistors and capacitors. This dev ....etc

Tri-gate transistors and methods to fabricate same
This invention provide a method for effecting uniform silicon body height for silicon-on-insulator transistor fabrication.In a form of the method, a sacrificial oxide layer is disposed upon a semiconductor substrate. The oxide layer is etched to form a trench. which is then filled with a semiconductor material. This deposited semiconductor material is then planarized with the remainder of the oxide layer and the remainder of the oxide layer is then removed.

Description
As t ....etc

In a world of ubiquitous presence of electrons can you imagine any other field displacing it? It may seem peculiar, even absurd, but with the advent of spintronics it is turning into reality.

In our conventional electronic devices we use semi conducting materials for logical operation and magnetic materials for storage, but spintronics uses magnetic materials for both purposes. These spintronic devices are more versatile and faster than the present one. One such device is spin valve transistor.

Spin valve transistor is different from conv ....etc

INTRODUCTION
Transistors are the microscopic, silicon-based switches that process the ones and zeros of the digital worlds and are the fundamental building block of all semiconductor chips. With traditional planar transistors, electronic signals travel as if on a flat, one-way road. This approach has served the semiconductor industry well since the 1960s. But, as transistors shrink to less than 30 nanometers (billionths of a meter), the increase in current leakage means that transistors require increasingly more powe ....etc
