Ton
A test carried out on silicon wafers after processing. The characteristics of standard test structures on the wafer are measured to determine if the wafer has been processed correctly. This provides immediate feedback about possible problems before the dice on the wafer are tested.
Test(ing) and Finish(ing)
The final stages of semiconductor manufacture where parts are tested, plated, symbolized and so on. Also known as "back-end" in the industry slang.
1) Technical Application
2) Traffic Announcement Feature of the Radio Data System (RDS). Radio stations providing traffic information transmit a Traffic Program (TP) identification code all the time. When traffic announcements are broadcast the TA code is sent too. When this is received a car radio normally selects the tuner and raises the volume to a present level.

Tetrachlorobenzene
Tetrachlorodibenzofuran
Tetrachlorodibenzo-para-dioxin
An aromatic halogenated hydrocarbon that is one of the most toxic compounds known to man. It is produced during the synthesis of the precursor chemical used in the manufacture of trichlorophenoxyacetic acid (2,4,5-T), a herbicide. The compound is toxic to liver and kidney functions and has been shown to induce a variety of tumors in animals. Adverse effects on the immune system of mammals have also been noted. Chloracne (a specific type of acne) is the most common symptom resulting from human exposure. TCDD has been involved in a number of well-publicized environmental cases, the most famous of which is contamination of the herbicide mixture known as agent orange used as a defoliant during the Vietnam War. Also referred to dibenzo-para-dioxin. Although it is but one of a large family of dioxins, it is often simply referred to as "dioxin".
Tetrachlorodibenzofuran
A polyhalogenated hydrocarbon found as a contaminant in commercial preparations of Polychlorinated Biphenyls (PCBs). This contaminant may be responsible for some of the adverse effects of PCBs. The molecule is very similar in chemical structure to tetrachlorodibenzo-para-dioxin (TCDD) and is frequently referred to as dibenzodioxin. The toxicity, potency, and biological effects are very similar to those of TCDD.

Test Equipment Inventory and Investment
Pioneering toll collection system developed by Italy's Autostrade SpA. Cars pass through tollgates without stopping. A microwave radio installation on the gate communicates with a small electronic device in each vehicle, identifying the user and determining the amount to be billed. ST contributed to the development of the first system and supplied most of the components.

- Thermal Compression Bonding
A method of wire bonding that does not use an intermediary metal or melting, but rather the plastic flow of materials resulting from the combination of heat and pressure. Also called
thermocompression bonding.
See Diffusion
A hybrid microelectronic process where conductors, insulators and passive components are screened from special pastes onto a substrate. This process is less expensive than the thin-film process, which uses depositions and photolithography techniques to define conductors, etc.
The use of deposited films of conductive or insulating material, which may be patterned to form electronic components and conductors on a substrate, or used as insulation material between successive layers of components.

Toxic Release Inventory
Toxic Chemical Release Inventory System
The first layer of the atmosphere, that closest to the surface of the Earth. The air surrounding the Earth consists of distinct zones, distinguished by the temperature gradient within each layer. The troposphere extends up about 16 to 18 km. in tropical regions and about 8 to 10 km in high latitudes. The air temperature in this layer decreases more or less continuously with increasing altitude. The troposphere contains about four-fifths of the mass of the atmosphere. Most of the air pollutants which get emitted at the Earth's surface are chemically broken down and/or deposited out in the troposphere.
Only few chemicals (notably the chlorofluorocarbons) are chemically stable enough to resist breakdown in the troposphere and eventually enter the layer above it, the stratosphere.
