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 ...
The semiconductor industry went through several stages of evolution, beginning with the Metal Oxide Semiconductor (MOS) Field-Effect Transistor (FET) which was first proposed by Lilienfeld and Heil in the 1930s, moving on to bipolar in the 1950s and N-channel metal-oxide semiconductor (NMOS) in 1970s, and ultimately becoming the standard in ...
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 ...
The Chinese Ministry of Commerce today announced immediate export restrictions on gallium, germanium, antimony, and super-hard materials to the United States. This action cites national security concerns and represents a significant escalation of trade tensions between the two countries. The restrictions follow recent U.S. actions to curb exports of semiconductor-related ...
Creonic’s DVB-S2 and DVB-S2X IP cores now include support for the new DVB-NIP standard on physical layer — an important step toward seamless integration of satellite and IP-based network technologies.
The DVB-NIP standard is designed to facilitate the native transport of IP over satellite networks, extending the capabilities of DVB-S2X by streamlining packet-based data delivery.
With ...
Focused Ion Beam (FIB) technology is one of the most versatile tools used in semiconductor failure analysis and microelectronics characterization. A FIB system directs a tightly focused beam of ions onto a sample. By controlling the beam current, energy, position and scanning pattern, engineers can remove material from extremely specific locations, ...
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 ...
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 ...
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 ...
