What is a Circuit Edit?
A circuit edit is when you need to modify an existing ASIC or integrated circuit for whatever reason. This is usually done with the help of an ion beam that is focused onto the chip to modify it as per the request of the designer. Engineers ...
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 ...
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 ...
IC short circuit failure analysis is the process of determining where an unintended electrical connection exists inside a semiconductor device, package or interconnect structure and identifying the physical defect that created the short.
A short circuit may initially appear only as excessive supply current, unexpectedly low resistance between two nodes, abnormal ...
With a rapid progression in the applications involving artificial intelligence, data generation has been increased exponentially in last few years. It has been estimated that in 2018, 2,5 quintillion bytes of data is generated every day [1]. This huge data generation puts enormous computational requirements on telecom platforms and data ...
Lately, there’s been a lot of buzz about silicon photonics in the data center industry. What’s it all about? The ever-expanding digital universe is being driven by cloud computing, mobile data, video streaming, and Internet-of-Things (IoT). Today, it’s estimated that by end of 2016, more than 6 zettabytes (i.e., 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 ...
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 ...
Introduction to Semiconductor
Semiconductors have a small energy gap between the conduction and valance bands, and their conductivity is between insulators and conductors. At absolute zero temperature, semiconductor materials are pure insulators and gradually increase with temperature. Temperature and doping are the two mechanisms to manage the conductivity of semiconductors. Doping ...
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 ...
