Semiconductor quality

wafer lot acceptance testing

Semiconductors; Semiconductor quality

Testing of an integrated circuit wafer lot to determine its acceptability for the assembly of Class S devices.

A region of surface conduction opposite in type from that expected from the bulk doping. Channels are sometimes introduced unintentionally by surface ionic contamination. The type of channel (P or N) ...

wedge bonding

Semiconductors; Semiconductor quality

See ultrasonic bonding (although Stitch bonding is occasionally called wedge bonding as well).

characterization

Semiconductors; Semiconductor quality

Electrical testing performed for the purpose of determining typical device performance characteristics and/or parametric limits.

weld seal

Semiconductors; Semiconductor quality

Semiconductor device sealing accomplished by welding a metal lid to a metal package (typically employed for metal can devices).

charge carrier

Semiconductors; Semiconductor quality

A carrier of electrical charge within the crystal of a solid state device, such as an electron or a hole.

x-ray

Semiconductors; Semiconductor quality

Radiographic analysis of the construction of a device. This is a less useful technique for devices with aluminum bond wires since only die attach and seal defects can be evaluated. For devices with ...
