The percent of devices on the wafer found to perform properly is referred to as the yield. Manufacturers are typically secretive about their yields, [188] but it can be as low as 30%, meaning that only 30% of the chips on the wafer work as intended. Process variation is one among many reasons for low yield. Testing is carried out to prevent ...
The FOAB device allegedly yields the equivalent of 44 tons of TNT using about seven tons of a new type of high explosive. Because of this, the bomb's blast and pressure wave have a similar effect to a small tactical nuclear weapon. [4] The bomb works by detonating in mid-air. Thermobaric weapons differ from conventional explosive weapons in ...
Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
Some sources give the yield for the Mod 0 as 250 tons of TNT (1,000 GJ) and the Mod 2 as 10 to 20 tons of TNT (42 to 84 GJ), [1] but declassified warhead development documents indicate the only difference between these two warheads was the environmental sensing devices used and that the warheads were field convertible, suggesting the weapons ...
The yield varies for a tactical nuclear weapon from a fraction of a kiloton to approximately 50 kilotons. [7] In comparison, a strategic nuclear weapon has a yield from 100 kilotons to over a megaton, with much larger warheads available. [7]
Wafer testing is a step performed during semiconductor device fabrication after back end of line (BEOL) and before IC packaging.. Two types of testing are typically done. Very basic wafer parametric tests (WPT) are performed at a few locations on each wafer to ensure the wafer fabrication process has been carried out successfully.

The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. The yield strength is often used to determine the maximum allowable load in a mechanical component, since it represents the upper limit to forces that can be applied without producing ...
