National Semiconductor Corporation designs, develops, manufactures, and markets analog and mixed-signal integrated circuits and sub-systems.
An impact-type shock test to stress die attach, wire bonds, and seal integrity, normally performed on a sample basis.
Industry:Semiconductors
The relocation or movement of physical materials into or across other adjacent materials. (See electromigration.)
Industry:Semiconductors
Subjection of sample devices to a cycle of high humidity and temperature stresses to determine the ability of these devices to survive under severe environmental conditions. This is normally performed on a sample basis with 10 cycles of 24-hour duration.
Industry:Semiconductors
An MOS process in which MOS transistors are formed by bridging two adjacent N-type diffusions (source and drain) with a dielectric (gate). When the source and the substrate are grounded and a positive voltage is applied to the gate, a conductive sheet of negative charge (N-channel) is created in the surface of the substrate under the dielectric.
Industry:Semiconductors
A junction transistor constructed by placing an N-type base between a P-type emitter and a P-type collector. The emitter is normally positive with respect to the base and the collector is normally negative with respect to the base.
Industry:Semiconductors
Electrical test of semiconductor devices at the wafer level, so named because a metal probe is used to make electrical contact with each of the device's bonding pads.
Industry:Semiconductors
A circuit element fabricated on a semiconductor device (usually adjacent to the device input) for the purpose of protecting portions of the device circuitry from transient overstress. A good example of a protective device would be an input diode on a CMOS device, which absorbs electrostatic discharge to prevent that discharge from rupturing the gate oxide.
Industry:Semiconductors
Semiconductor material in which the majority carriers are holes and are therefore positive.
Industry:Semiconductors
Conformance to a set of predetermined design and workmanship standards. Quality and reliability are not synonymous.
