National Semiconductor Corporation designs, develops, manufactures, and markets analog and mixed-signal integrated circuits and sub-systems.
The physical elements and interfaces that constitute a component or system.
Industry:Semiconductors
Leak or seal testing performed on all hermetic packages to confirm seal integrity. This is done in two steps, fine leak, which looks at leak rates in the 5 x 10-8 cc/sec range, and gross leak, which looks for devices with gross seal defects.
Industry:Semiconductors
The absence of a valence electron in a semiconductor crystal. The movement of a hole is equivalent to the movement of a positive charge.
Industry:Semiconductors
A dielectric layer used to isolate multilevel conductive and resistive material or to protect top level conductive resistive material (see glassivation, passivation).
Industry:Semiconductors
Introduction into a semiconductor of selected impurities in controlled regions (via high voltage ion bombardment) to achieve desired electronic properties.
Industry:Semiconductors
The boundary between a P-region and an N-region in a silicon substrate.
Industry:Semiconductors
Similar to an LTPD, except that it is expressed in percent per thousand hours.
Industry:Semiconductors
A semiconductor building block containing a relatively complex electronic function that can be combined through CAD with other cells to perform a complex function with less design effort than a complete "ground-up" design.
Industry:Semiconductors
A patterned screen of any of several materials used to expose selected areas of a semiconductor covered with a light-sensitive photoresist to polymerizing light during the fabrication process.
