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 ...
Overview of Silicon-Germanium (SiGe) Technology and Historical Development
Shockley's early transistor game most likely inspired the notion of fusing silicon (Si) and germanium (Ge) to create an alloy for use in transistor engineering. However, this concept has just become a reality in the last 15 years due to the challenges associated ...
Getting funding for a semiconductor startup is not getting easier. According to CBIngishts, there have been fewer than 20 Angel/Seed and Series A deals in the USA in each year since 2009.
So where is all the funding channeled to? In 2013, close to a quarter of all VC funding was ...
One of the leading manufacturers of automatic test equipment, Advantest has proven to be one of the leading lights in the semiconductor industry. In addition, they manufacture measuring instruments that are used in the creation of electronic system. You can find Advantest products used in the creation of digital consumer ...
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 ...
Transmission Electron Microscopy (TEM) is one of the highest-resolution physical-analysis techniques used in semiconductor failure analysis. It allows failure analysts to examine extremely small structural and material anomalies that may be impossible to characterize using optical microscopy or conventional SEM alone.
TEM works by transmitting a high-energy electron beam through an ...
Once an electrical failure has been localized inside an integrated circuit, the next challenge is determining what physically went wrong. Was a metal interconnect broken? Did a via fail? Is there contamination between two structures? Has a dielectric layer broken down? Is a transistor structure abnormal? Or did the failure originate in the ...
Many important semiconductor package defects are completely hidden from optical inspection. A solder ball can contain a void. A bond wire can be broken inside an encapsulated package. A die-attach layer may contain large areas of voiding. A package substrate can contain an open trace, and an advanced package may have ...
When an integrated circuit fails, one of the first questions is: How is the device failing electrically?
A chip may exhibit excessive leakage current, a short circuit, an open connection, abnormal supply current, a parametric shift or a complete functional failure. Before engineers physically cut into the device, they usually want to ...
