Dear Dudes,

What is meant by hot spots and where does it occur.

Related to what problem this cause.

with regards

Hi,
Please elaborate the context. Are you talking on hot spot in communication systems ?

 

[A.Anand Srinivasan]

hotspots are formed when there the non uniform doping... due to this there is different resistances distributed this leads to heating at certain spots of high resistance and this may lead to melting and formation of short circuits which ultimately damage the device....

 

[rajiv87]

hot spot is form in case of doppig of semiconductor material. due ununiform dopping like dust partical there is space or dust in joint or dopping which lead in temp raising

Dear Anand,

While doping if the concentration goes more it leads to hot electron effect amd ion

degradation in deep sub micron cmos circuits which depends on applying voltage .

but there is term caled hot spots which has a particular defintion and it arises due to a certain problem.

I need that. i want to know that.

it is not related to how high or low the doping is... it is about variation in doping...
