electromigration การใช้

• This artifact is especially common with nanogaps produced by the electromigration method.
• Electromigration decreases the reliability of chips ( integrated circuits ( ICs ) ).
• In modern consumer electronic devices, ICs rarely fail due to electromigration effects.
• Nevertheless, there have been documented cases of product failures due to electromigration.
• But here the researchers employed electromigration to burn, or open, a fuse.
• It is also intrinsically less susceptible to electromigration.
• Electromigration is an equally serious concern, but is attacked with almost identical methods.
• Controlling gaps on these scales by means of electromigration can produce interesting electrical properties.
• Electromigration and delamination at contacts are also a limitation on the lifetime of electronic devices.
• Nonhomogenous distribution of current also aggravates electromigration effects and formation of voids ( see e . g.
• The current density must be sufficiently high to push the domain walls ( as in electromigration ).
• This is because proper semiconductor design practices incorporate the effects of electromigration into the IC's layout.
• Electromigration occurs when some of the momentum of a moving electron is transferred to a nearby activated ion.
• Diffusion processes caused by electromigration can be divided into grain boundary diffusion, bulk diffusion and surface diffusion.
• The lifetime of the CPU is also extended because of reduced electromigration, which varies exponentially with temperature.
• High average current densities lead to undesirable wearing out of metal wires due to electromigration ( EM ).
• An example of a conductor which exhibits whisker growth due to electromigration is shown in the figure below:
• Black used this knowledge, in combination with experimental findings, to describe the failure rate due to electromigration as
• The researchers took advantage of a physical phenomenon, electromigration, that traditionally causes trouble in metallic connectors in circuits.
• These layers may cause mechanical reliability weakening and brittleness, increased electrical resistance, or electromigration and formation of voids.
