Semiconductor quality

date code

Semiconductors; Semiconductor quality

A three- or four-digit number identifying the inspection lot from which material was selected. The first two digits (or first digit for a three-digit code) identify the year, the last two the week. ...

delta

Semiconductors; Semiconductor quality

A limit applied to the amount of parametric drift that a unit may display across a screen or series of screens (usually applied to burn-in).

depletion layer

Semiconductors; Semiconductor quality

The region in a semiconductor where essentially all charge carriers have been swept out by the electrical field which exists there.

alloying

Semiconductors; Semiconductor quality

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 ...

source inspection

Semiconductors; Semiconductor quality

Surveillance or inspection by a customer's quality representative or by a government inspector at the vendor's facility of material being assembled or screened by that vendor.

alpha particles

Semiconductors; Semiconductor quality

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 ...

specification control drawing

Semiconductors; Semiconductor quality

Per MIL-STD-100, a drawing prepared for the purpose of defining and controlling screening, electrical performance characteristics, and physical configuration of purchased material. By definition, the ...
