Gallium Arsenide
A compound semiconductor material in which active devices are fabricated. GaAs has a higher carrier mobility than silicon, thus it has the capability of producing higher speed devices.
A discrete device used to amplify higher frequency radio signals.
The proposition that the composition and temperature of the atmosphere is a product of interrelated activities in the biosphere, especially those of microorganisms, and that the biosphere behaves as a single self-regulating organism. Gaia was the ancient Greek goddess of the Earth. The hypothesis was developed by the British scientist James Lovelock and American biologist Lynn Margulis. (Lovelock was also the scientist who discovered that chlorofluorocarbons were not broken down in the troposphere).
Generic Array Logic
Compound used to produce light-emitting diodes and very fast integrated circuits.

US market research company specialized in electronics markets.
One of the three states of matter. In the gaseous state, there is little attraction between the particles, which have continual, random motion. The gas has no fixed shape or volume, can expand indefinitely, and can assume the shape of the space in which it is held. It is also easily compressed, with the random collisions between particles exerting pressure on the walls of the container.
1) The basic digital logic element - where the binary value of the output depends on the values of the inputs.
2) The primary control terminal of a field effect transistor.
An IC consisting of a regular arrangement of gates that are interconnected to provide custom functions.
Sometimes called an Uncommitted Logic Array (ULA).
The number of transistors that can be placed on a silicon chip in a unit area. With a 0.35 micron process, a gate density of 18,000 gates per square millimeter can be achieved, but moving to 0.25 micron, the gate density rises to more than 35,000 gates per square millimeter.
The basic unit of measure for digital circuit complexity, based on the number of individual logic gates that would have to be interconnected to perform the same circuit function.
The thin layer of thermal oxide separating the gate electrode (terminal) from the semiconductor substrate.
A computer which interconnects two different networks.

- Global warming potential (GWP)
A measure of the potential of substances (normally gases or volatile liquids) to heat up the atmosphere. All measures of GWP are given relative to Carbon dioxide, the most well-known gas with global warming potential, which has a GWP of 1.

GNP (or GDP) measures the total wealth created in a given period of time (a year) in a country.
1) Gross Operating Profit
This is the result of Sales minus operating costs (excluding financial charges and exceptional PL items). To obtain the PBT (Profit Before Taxes), we subtract from GOP charges as debt interests, specific restructuring costs and non recurrent expenses and add non-operating income.

A term used primarily in Europe to cover all associations whose objective is to defend the environment. The political extremism of an association is denoted by its hue: the more extreme groups are denoted "Deep Greens" while the more moderate groups are denoted "Light Greens".
The predicted increased warming of the atmosphere resulting from the accumulation of atmospheric carbon dioxide and other gases with global warming potential. The atmosphere is normally warmed when infrared radiation emitted by the Earth is absorbed by carbon dioxide gas and water vapor in the atmosphere. It has been hypothesized that as the amount of carbon dioxide increases due to the combustion of fossil fuels and deforestation, especially of tropical rain forests, more heat energy will be retained by the Earth's atmosphere, resulting in a rise in its temperature. This in turn could result in changes in rainfall and wind patterns and melting of polar ice, thus raising the global sea level. The change in weather patterns could have devastating consequences to the world's present prime agricultural areas. A significant rise in sea level could flood many coastal cities and damage ecologically important coastal wetlands. Other gases with global warming potential whose concentrations in the atmosphere are increasing in the atmosphere as a result of human activities are methane, nitrous oxide, the chlorofluorocarbons and the perfluorocarbons.
A personal computer that consumes less power, complying with the Environmental Protection Agency's Energy Star standard.

Total dice on wafer
A term used to describe the water which is found below ground. This water, which in most cases is derived from water seeping into the ground, is found in those geological formations which have a certain porosity. Groundwater is commonly abstracted through wells and is a major source of drinking water, irrigation water and industrial water in many parts of the world. Relative to surface waters, groundwater moves extremely slowly - a flow of meters a day is considered very fast. Because of this, any contaminants which enter groundwater are flushed away only very slowly. This fact, together with its importance as a source of water, makes contamination of groundwater a very critical environmental issue in many circumstances.
- Groundwater contamination
The pollution of springs and wells from their sources underground. It can result from indiscriminate land disposal of potentially hazardous waste materials that are then dissolved or suspended in free liquids, usually water, and leach downward through the unsaturated profile to the zone of saturation or from improperly constructed or operated wells.
The periodic sampling and analysis of changes in concentrations of chemical constituents in groundwater.
A volume of contaminated groundwater in an aquifer that extends downward and outward from a specific source of contamination; the shape and movement of the mass of the contaminated water is affected by the local geology, materials present in the plume and the flow characteristics of the area's groundwater. In some locations, where the conditions are particularly favourable to their formation, plumes kilometers long have formed in aquifers.
