MOS transistor is the building block of integrated circuits, and is the engine that powers them. Today?s most complex ICs, such as microprocessors, graphics, and DSP chips, pack more than 100 million MOS transistors on a single chip. Integration of one billion transistors into a single chip will become a reality before 2010.

The semiconductor industry faces an environment that includes increasing chip complexity, continued cost pressures, increasing environmental regulations, and growing concern about ....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.

PHOTOTRANSISTOR A LEAP OF OPTOELECTRONICS

Like diodes, all transistors are light-sensitive. Phototransistors are designed specifically to take advantage of this fact .the most-common variant is an NPN bipolar transistor with an exposed base region. Here, light striking the base Replaces what would ordinarily be voltage applied to the base “ so, a photo- transistor amplifies variations in the light striking it. Phototransistors may or may not have a base lead . (if they do, the base lead allows us to bias the phototransis ....etc

The need for high-performance, low-power, and low-cost systems for network transport and wireless communications is driving silicon technology toward higher speed, higher integration, and more functionality. Further more, this integration of RF and analog mixed-signal circuits into high-performance digital signal-processing (DSP) systems must be done with minimum cost overhead to be commercially viable. While some analog and RF designs have been attempted in mainstream digital-only complimentary metal-oxide semiconductor (CMOS) technologies, al ....etc
