Gallium arsenide (GaAs) technology is a type of semiconductor material used in the manufacturing of various electronic devices. It is known for its high electron mobility, which allows it to operate at higher speeds and with lower power consumption compared to other semiconductor materials such as silicon. GaAs technology is ...
When a semiconductor device fails, the visible damage is not necessarily the root cause. A damaged metal line, cracked package, leaking transistor or burned bond wire may be the final result of a sequence of events rather than the original problem. The purpose of the semiconductor failure analysis process is therefore to ...
Integrated circuits can fail for many different reasons. Some failures originate inside the semiconductor die, while others result from packaging, manufacturing, assembly, electrical overstress or the environment in which the device operates. Common IC failure mechanisms include electrostatic discharge (ESD), electrical overstress (EOS), electromigration, dielectric breakdown, interconnect defects, corrosion, contamination, thermal ...
Many semiconductor failure-analysis techniques require direct access to structures that are hidden inside an IC package. The semiconductor die, bond pads, bond wires and other critical components may be completely covered by epoxy molding compound or other packaging materials. Before these structures can be examined using techniques such as optical microscopy, emission ...
Scanning Electron Microscopy (SEM) is one of the most important imaging techniques used in semiconductor failure analysis. While optical microscopes remain extremely useful for initial inspection, many semiconductor defects are simply too small to characterize adequately with visible-light microscopy. SEM uses a focused beam of electrons rather than light, allowing engineers ...
SINGAPORE and SAN JOSE, Calif., Nov. 02, 2016 (GLOBE NEWSWIRE) -- Broadcom Limited (Nasdaq:AVGO) and Brocade Communications Systems, Inc. (Nasdaq:BRCD) today announced that they have entered into a definitive agreement under which Broadcom will acquire Brocade, a leader in Fibre Channel storage area network (“FC SAN”) switching and IP networking, for $12.75 ...
Package failure analysis is the systematic investigation of defects and failures originating within semiconductor packaging, interconnects, solder connections, die attach, bond wires, redistribution layers and other structures that connect the semiconductor die to the outside system.
A semiconductor device may fail electrical testing even though the silicon itself is functioning correctly. ...
Scanning Acoustic Microscopy (SAM) is a non-destructive imaging technique widely used in semiconductor failure analysis to inspect structures and interfaces hidden inside IC packages. Unlike optical microscopy, which relies on visible light, or X-ray inspection, which relies primarily on differences in material density and X-ray absorption, SAM uses high-frequency acoustic waves. This ...
The factors affecting silicon wafer cost are numerous. From the resistivity required for different applications to the physical size of the wafers, and not least the quality grades that separate the pristine from the less perfect; each aspect intricately influences the cost.
As we embark on this explanation, we'll unwrap the ...
With the creeping rise in the price of gold, many microelectronics manufacturing companies have been looking for alternatives to reduce the cost of ball bonding. Recently, the trend has been to look into the use copper wire. However, there are many drawbacks to using copper wire, including the short shelf ...
