When an integrated circuit fails, identifying the damaged component is only part of the challenge. Engineers must determine where the failure occurred, what physical or electrical mechanism caused it, and ultimately why it happened. This requires a combination of specialized IC failure analysis techniques. Some techniques detect electrical abnormalities without physically altering ...
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 ...
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 ...
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, ...
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 ...
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 ...
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 ...

OBIRCH (Optical Beam Induced Resistance Change) is a laser-based fault-localization technique used in semiconductor failure analysis to identify electrically abnormal regions such as resistive shorts, leakage paths, defective vias and interconnect problems.
The technique works by scanning a focused laser across an electrically biased semiconductor device. Local laser heating changes the ...
