A SONOS memory cell is formed from a standard polysilicon NMOS transistor with the addition of a small sliver of silicon nitride inserted inside the transistor's gate oxide. The sliver of nitride is non-conductive but contains a large number of charge trapping sites able to hold an electrostatic charge. The nitride layer is electrically isolated from the surrounding transistor, although charges stored on the nitride directly affect the conductivity of the underlying transistor channel. The oxide/nitride sandwich typically consists of a 2 nm thi ....etc

CHAPTER 1
ABSTRACT
Micro photonics is the successor of electronics .It has many advantageous features for application in space through the combination of micro, nano integrated optics and fiber optic technologies .Based on current technical feasibility, potential impact on space systems and significant benefits; it is proposed that micro photonic satellite navigation systems can be developed with the target of a space demonstration flight .The proposed methodology is generic to the needs of all space craft; can provid ....etc

Silicon photonics can be defined as the utilization of silicon-based materials for the generation (electrical-to-optical conversion), guidance, control, and detection (optical-to-electrical conversion) of light to communicate information over distance.

The most advanced extension of this concept is to have a comprehensive set of optical and electronic functions available to the designer as monolithically integrated building blocks upon a single silicon substrate.


Within the range of fibre optic telecommunication wavelength (1.3 ?m to ....etc

Microphotonics is a branch of technology that deals with directing light on a microscopic scale. It is used in optical networking.

Microphotonics employs at least two different materials with a large differential index of refraction to squeeze the light down to a small size. Generally speaking virtually all of microphotonics relies on Fresnel reflection to guide the light. If the photons reside mainly in the higher index material, the confinement is due to total internal reflection. If the confinement is due many distributed Fresnel reflect ....etc

The rapid improvement in silicon technology has enables the electronic industry to progress steadily over the past 50 years.

It is this technological stride that make computers to shrink in cost and size .But a question still persists whether the present rate of progress will continue for the next 50 years. The essential ingredient to the progress had been the process of miniaturization.

The road to advances beyond a decade into the future has always been obscure and has stimulated many speculations as to where miniaturization must end. ....etc
