The gaseous form of a material that is normally found in the solid or liquid state at room temperature. Vaporization occurs when particles in the solid or liquid gain enough energy to escape the material, especially with an increase of temperature. The term is frequently employed to refer to water in the gas phase: "water vapor".
A vacuum process, usually at less than 10 -6 Torr (mmg of Hg), where metal(s) are vaporized through thermal agitation, then recrystallized on cooler surfaces, generally the material to be coated. Also referred to as evaporation.
The process for coating the wafer surface with HMDS
VARiable
The dispersion or scatter exhibited by evaluations of successive events resulting from a common process.
Change in the value of a measured characteristic. Sources of variation can be grouped into two major classes: common causes and special causes.

Very High-Speed Integrated Circuit
A path filled with conducting material between circuit layers.
A gaseous organic compound composed of carbon, hydrogen, and chlorine. Vinyl chloride is used to make the plastic polyvinyl chloride (PVC). Vinyl chloride is one of the few chemicals which is known with certainty to be a cause of cancer in humans. In the 1960's-70's, medical and epidemiological studies showed that occupational exposure to vinyl chloride caused an extremely rare liver cancer, angiosarcoma. Discovery of this led to extremely tough standards on occupational exposure to vinyl chloride, so tough that the PVC industry feared that for its continued existence. However, the industry rose to the challenge and has continued to be able to manufacture PVC at economically acceptable prices while meeting the stringent occupational TLV's for vinyl chloride.
Video Interface Port
VIPower is a family of proprietary ST technologies in which discrete power structure are inte-grated with analog and digital control and diagnostic circuitry, resulting in a device that com-bines the robustness of discrete technology with integrated control and diagnostic circuitry.
An undesired computer program designed to copy itself from one disk to another furtively. Some simply announce their presence, others cause loss or damage to information.
A definition or description of how we want to be viewed by our stakeholders at some fixed time in the future. It defines what kind of company (or division, or department) we want to become as well as how well we should perform. It can have both descriptive and numeric objective.

Volatile Organic
Volatile Organic Compounds
A category of organic compounds with relatively high vapor pressures, they are a major air contaminant. Most VOCs are carbon-hydrogen compounds (hydrocarbons), but they also may be aldehydes, ketones, chlorinated hydrocarbons, and others. Thousands of individual compounds exist, including the unburned hydrocarbon compounds emitted from automobiles or industrial processes and the organic solvents lost to evaporation from household, commercial, or industrial cleaning and painting operations, and other activities. Most VOCs participate in the atmospheric reactions that lead to photochemical air pollution ("photochemical smog"), and excessive exposure to certain individual compounds is associated with skin irritation, central nervous system depression, and/or an increased risk of cancer.
