Carbon
An element present in all materials of biological origin. The element contains six protons and usually six neutrons in the nucleus. Carbon atoms may bind with each other as well as with a host of other elements. Deposits derived from living sources, such as limestone, coal, oil, and natural gas, contain carbon as a principal element. Graphite and diamonds are composed almost exclusively of carbon.

A gas made out of two atoms of oxygen and one atom of carbon (chemical formula CO2). It is the product of aerobic respiration, decomposition and carbon fuel consumption. It plays a fundamental role in the respiration process. The concentration of carbon dioxide in the atmosphere changes depending on the season of the year: it reaches its maximum in fall/winter (when tree respiration prevails) and its minimum in spring/summer (when trees /photosynthesis prevails). Carbon dioxide is also released by combustion of fossil fuels (gas, oil, coal) through industrial activities and transportation, and is causing an increase of the carbon dioxide concentration in the atmosphere. Some measurements indicate that this concentration has increased from 270 ppm to 350 ppm in the last 200 years. Because carbon dioxide absorbs infrared radiation, rising levels of carbon dioxide in the atmosphere have prompted concerns about climatic change (see Greenhouse effect).
An odorless, colorless, and tasteless gas that is an air contaminant formed by the incomplete combustion of carbon fuels, such as wood, coal, or gasoline. Classed as an asphyxiant gas, absorbed carbon monoxide combines with hemoglobin in the blood to form carboxyhemoglobine which impairs oxygen delivery to the tissues. The major source for human exposure is the car.
A radioactive isotope of carbon that emits beta particles when it undergoes radioactive decay. The nucleus of a 14C atom contains eight neutrons rather than the six neutrons found in 12C, which is the most abundant isotope in nature.
Carbon-14 is formed naturally in the Earth's atmosphere through the interaction of nitrogen gas in the air with cosmic rays. The atmospheric 14C thus produced, combines with atmospheric oxygen and is converted to carbon dioxide (14CO2). Because the radioactive form of carbon dioxide mixes with the normal, nonradioactive, carbon dioxide in the atmosphere and because the radioactive and nonradioactive forms of carbon dioxide undergo the same chemical reactions, both forms can be found in living plant tissue as a result of /photosynthesis. While the plant is alive, the ratio of 14C to 12C remains about the same as time passes. However, when the plant dies, carbon dioxide from the air is no longer incorporated into the plant mass. The radioactive form of carbon decays with a half-life of about 5760 years; consequently, the ratio between the two isotopes in the dead plant changes as time passes and the radioactive carbon decays. The changes in this 14C : 12C ratio can be used to date materials. If a buried tree contains one-half of the radioactive carbon that one finds in a live tree (relative to the amount of normal carbon present), the tree is approximately 5760 years old. Materials older than 70,000 years cannot be aged by this technique since almost all of the radioactive carbon has decayed. Carbon-14 is also known as radiocarbon.
Holes or electrons that are available in a semiconducting device for conduction of electric current.
An inert gas used to transport other elements to a process chamber or tube.
Hole - or negative electron - electrical charge.
Free carriers are charges that move within the material. The majority carriers are those which are dominant in a semiconductor. For example, in a N-type semiconductor, the majority carriers are electrons.

Negative chlorine ions (Cl-), found naturally in some surface waters and groundwaters and in high concentrations in seawater. Higher-than-normal chloride concentrations in fresh water, due to sodium chloride (table salt) that is used on foods and present in body wastes, can indicate sewage pollution. It can also be due to industrial discharges, especially where waste hydrochloric acid is neutralized. The use of highway de-icing salts can also introduce chlorides into surface water or groundwater. Elevated groundwater chlorides in drinking water wells near coastlines may indicate saltwater intrusion.
- Chlorinated organic compounds
Synthetic chemical substances containing chlorine, hydrogen, and carbon, obtained by the chlorination of organic compounds. The presence of chlorine in organic compounds generally causes these materials to break down slowly in the environment - this is a sign of the fact that very few chlorinated organic compounds exist naturally, so that the environment's natural decomposers have not evolved to break them down. Many classes of chlorinated hydrocarbons are industrially important. One of the most well-known are the chlorinated solvents, which are implicated in many cases of environmental contamination. The best known of this class are carbon tetrachloride, chloroform, methylene chloride, trichloroethylene (TCE), tetrachloroethylene (also known as perchloroethylene, or "perc") and 1,1,1-trichloroethane (TCA). Polychlorinated biphenyls (PCB) as well as chlorinated phenols, both families which have been implicated in environmental contamination, are part of this group. The chlorofluorocarbons (CFC) are also in this family.
Finally, many of the first generation of insecticides which were found in the late 1960's to have severe environmental implications, are chlorinated hydrocarbons, including DDT, mirex, aldrin, kepone, lindane, heptachlor, toxaphene, and many others.
The addition, through various types of chemical reaction, of chlorine to organic compounds. It is also the process of adding chlorine to water or wastewater in order to kill or inactivate dangerous microorganisms or viruses. Chlorine in various forms, such as chlorine gas, bleach, or solid chlorine-containing compounds, can be used.
One of a group of elements classified as the halogens. Chlorine, the most common halogen, is a greenish yellow gas with an irritating odor. Chlorine is very reactive; it forms salts with metals, forms acids when dissolved in water, and combines readily with hydrocarbons. A major use of chlorine is in the organic chemicals industry where it is used as a raw material for the production of the numerous chlorinated organic compounds still in use. It is also used in large quantities by the paper industry, either as the gas or in the form of hypochlorite, where it is used to bleach paper to make it whiter. Various forms of chlorine are also used to disinfect water. Chlorine is produced by the electrolysis of brine (concentrated salt solution).
- Chlorofluorocarbons (CFCs)
A class of simple hydrocarbon derivatives in which chlorine and fluorine are substituted for some or all of the hydrogen atoms (e.g., CCl2F2). They are commonly called freons, which is a Dupont de Nemour's registered trade mark. They are denoted by a numbering system, the most common being CFC-11, CFC-12, CFC-113 and CFC-115. As a group, these compounds are volatile, nonreactive, noncorrosive, and nonflammable. They were used widely in consumer products (propellants in aerosol sprays, and coolants in refrigerators and air conditioners) and in industrial applications (as a solvent and to blow various types of plastic foam, e.g. polyurethane foams and "Styrofoam"). The chlorofluorocarbons have been implicated in the reduction of the ozone content of the stratosphere (ozone layer), and are greenhouse gases.

A term used to denote process technologies which use less natural resources and/or generate less waste or pollution than existing ones.
The decontamination of water, soil or an aquifer that is determined to contain concentrations of a leaked or spilled substance that threatens public health or the environment. Cleanup is normally divided into either on-site cleanup or off-site cleanup. On-site cleanup consists of the treatment of the contaminated media without removing it. Off-site cleanup consists of the removal of the contaminated material for treatment or disposal in off-site facilities. Cleanup technologies commonly used are: thermal treatment, where the contaminated media are heated to temperatures that destroy the pollutants; physical treatment, where air or water are used to extract the pollutant from the contaminated media for further treatment; chemical treatment, where solvent or other chemicals are used to extract the pollutant from the contaminated media for further treatment; biological treatment, where selected microorganisms decompose the pollutants. The use of these technologies depends on the type of contamination and the environmental media contaminated.

Consigned Inventory
The amount of chemical substance in a given amount of air, water, soil, food, or other medium. The value can be expressed as the mass of the chemical in a given mass of the medium, the volume of the chemical in a given volume of the medium, or the mass of the chemical in a given volume of the medium. For gaseous air contaminant concentrations, two expressions are appropriate: a volume/volume ratio and a mass/volume ratio. The volume/volume ratio units are typically parts per million (volume) (ppm(v)) or parts per billion (volume) (ppb(v)), equivalent to one liter of pollutant in one million liters of air or in one billion liters of air, respectively. The mass/volume units are typically milligrams or micrograms of pollutant per cubic meter of air. For airborne particulate matter (dust), only mass/volume units are used, typically micrograms of particulate per cubic meter of air. In water, mass/volume and mass/mass ratios are used; the volume and mass of the aqueous medium are easily interchanged because one liter of water has a mass of one kilogram. Typical units are milligrams or micrograms of pollutant per liter of water, which is equivalent to parts per million (mass) (ppm) or parts per billion (mass) (ppb), respectively. Soil and food concentrations are mass/mass ratios, in milligrams or micrograms of a chemical per kilogram of food or soil, which is the same as parts per million (mass) (ppm) or parts per billion (mass) (ppb), respectively.
The level of dopant materials as compared to "pure" semiconductor materials within the structure. The net concentration establishes the characteristic conduction pattern and other characteristics of the material.

Cost Of Non-Quality
(also called Price of non-conformance, and often referred to as Cost Of Quality)
This is the cost incurred by quality problem. It includes costs of replacement, repair, reworking and failure analysis. Usually analyzed by cost of prevention, cost of detection, cost of internal failure and cost of external failure. Ideally cost of prevention should be separated and treated as an investment, to reduce the other three costs.
An optical system that uses contact printing (the mask touches the wafer) to expose a wafer.

Consorzio Ricerca Microelettronica per il Mezzogiorno
Small town west of Milan, Italy, where ST Castelletto Laboratory is located.
The cost of acquiring raw materials, components, subsystems, etc. In calculating the cost of ownership it is necessary to add to the initial purchase price additional costs such as:
- Cost of quality control on receipt of the item;
- Cost of 100% inspection;
- Cost of reliability tests;
- Cost of stock in warehouse;
- Unwanted production cost induced by Quality problems; v- Cost in the field due to reliability problems;
- Cost due to loss of customer.
Law purchasing costs (which may reflect poor material quality) can be nullified by the additional costs the Company will incur subsequently (see also Partnership).
The same concept can be applied to an individual purchasing a car. The owner will have to add the costs of breakdowns, to the basic purchasing price.
(Capability index)
The capability index indicates the relationship between the product's specification (planned tolerances) and the process capability or spread (natural tolerance of the production process). The process has to be in statistical control, i.e. only common causes of variation are present.
When the Cp increases, the margin between what the process is "capable" of producing and what it is required to produce become wider. With a Cp of 1 the percentage of rejects is about 0.3%, or 3000 parts per million (PPM) (also known as the condition of 3 sigma).
With a Cp of 2, the rejects are about 0.0007%, or 7 PPM (condition of 6 sigma).

Process capability When a process is in statistical control we need to measure its ability or fitness for meeting a specification. A good measurement is Cpk: it takes into account both centering and dispersion (accuracy and precision). When both the Cp and Cpk have the same value, it indicates that the process is centered with the nominal value of the product specification. This is the optimum condition. When the process suffers from the effect of variables which drift in time, and it is no longer centered with the nominal value of the product, it is useful to know the value of Cpk. While the value of Cp may remain unchanged, the value of Cpk may vary.
The Cpk calculated with the data obtained from a process provides the measure of the performance of that process.
