National Semiconductor Corporation designs, develops, manufactures, and markets analog and mixed-signal integrated circuits and sub-systems.
The anticipated lifetime of a device, how long it can be expected to "survive" in the user's system. This is normally defined as a failure rate (percent per 1000 hours) or as an MTBF (Mean Time Between Failures, expressed in hours).
Industry:Semiconductors
A device or devices randomly chosen from a lot of material. Sampling assumes that randomly selected devices will exhibit characteristics during testing that are typical of the lot as a whole.
Industry:Semiconductors
An element, such as silicon or germanium, that is the intermediate in electrical conductivity between the conductors and the insulators.
Industry:Semiconductors
A hybrid device having an inner seal perimeter (i.e., a cavity perimeter) of less than 2 inches.
Industry:Semiconductors
The instructions which program or sequence the functioning of the hardware of a device or system. These instructions may be contained internally (in ROM, for example) or externally (on tape, disc, or any other suitable memory medium).
Industry:Semiconductors
An impurity that can make a semiconductor P-type by accepting valence electrons, thereby leaving "holes" in the valence band of the semiconductor device. The holes act like carriers of positive charge.
Industry:Semiconductors
The step in the fabrication process immediately following evaporation. This process alloys the conductive metal which had been deposited on the die surface to that surface, thus providing ohmic contact with the active circuit elements.
Industry:Semiconductors
Helium nuclei emitted as a result of the radioactive decay of trace amounts of naturally occurring uranium and thorium found in semiconductor packaging materials. Alpha particles, if not properly controlled, can cause soft errors in dynamic memories.
Industry:Semiconductors
A microcircuit in which the output is a mathematical function of the input.
