The time-dependent dielectric breakdown (TDDB) in on-chip interconnect stacks is one of the most critical failure mechanisms for microelectronic devices. This paper demonstrates the procedure of an in situ TDDB experiment in the transmission electron microscope, which opens a possibility to study the failure mechanism in microelectronic products.

During the 1960s, a stable trade-off between the inflation rate and the unemployment rate was observed, as represented by the Phillips curve. According to this relationship, low unemployment was generally associated with high inflation, while high unemployment was associated with low inflation. However, during the 1970s, this relationship broke down.A sharp rise in oil prices in 1973 led to higher production costs across various industries. At the same time, unemployment also increased,...

The movement of electrons in a conductor requires some form of energy or work, usually provided by an external force, like a battery. This force is called the electromotive force or voltage. The voltage between two points, referred to as points "a" and "b," in an electric circuit is the energy (or work) needed to move a unit charge from point "a" to point "b," and this relationship is expressed mathematically as In this equation, "w" represents the energy measured in joules (J), and "q"...

Laser-induced breakdown spectroscopy performed on thin organ and tumor tissue successfully detected natural elements and artificially injected gadolinium (Gd), issued from Gd-based nanoparticles. Images of chemical elements reached a resolution of 100 μm and quantitative sub-mM sensitivity. The compatibility of the setup with standard optical microscopy emphasizes its potential to provide multiple images of a same biological tissue.

Generally, a single battery is not enough to power some devices. In such cases, batteries can be combined in two ways: in series or in parallel. In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series. Batteries are...
FAQs
A strong electric field can accelerate mobile charge carriers until they acquire enough energy to ionize atoms. The resulting additional carriers may create carrier multiplication, causing current to rise sharply rather than increase gradually. This microscopic process explains why an insulating region can abruptly change from weak conduction to a highly conductive state.
The threshold varies with the material and with its operating environment and structure. Temperature and pressure affect the conditions under which carriers gain energy, while geometry changes the local electric field. Defects can also weaken insulation by concentrating the field or creating vulnerable regions, so nominal voltage alone does not determine performance.
Breakdown is governed by the electric field experienced within a material, not only by the applied potential difference. Geometry can produce regions of enhanced field, and defects can create localized weak points where carrier activity becomes significant sooner. Evaluating these features helps relate a measured voltage threshold to practical insulation strength and device reliability.
Designers treat the voltage threshold as a practical indicator of how much electrical stress insulation can withstand. Its value informs choices for high-voltage cables, capacitors, switches, and power systems, where unexpected conduction could impair operation or cause failure. Considering material, temperature, pressure, geometry, and defects supports more reliable insulation decisions.
A controlled breakdown can serve a deliberate circuit function, particularly in voltage regulation and protection circuits. In these applications, the transition to sharply increased current is used as part of the intended electrical behavior. By contrast, an uncontrolled transition in insulation or a device may produce permanent damage or electrical failure.
Breakdown-voltage characteristics are relevant across several electrical technologies, including semiconductor diodes, capacitors, switches, high-voltage cables, and power systems. The characteristic helps connect a device or insulating component to its allowable electrical stress and reliability requirements. It is therefore useful both for selecting components and for interpreting possible failure risks in operating systems.
