How the diffuction act as path for charges in antena error

[holla1112]

During antena error in metal chargers will accoumulate.
1) those are posive charges or negetive charges???
2) how the diffution can became a path to charges in antena

can any one plz ans dis..??

Right!

1) those are posive charges or negetive charges???

Both are possible. However, metals are mostly structured by negative ions (F^-, Cl^-).

2) how the diffution can became a path to charges in antena

Any diffusion is residing in silicon, i.e. either directly in substrate, or via a junction (even in break down direction this is non-destructive at these low antenna currents).

can u plz explian more about non destructive..??? how a positive or negetive chagre can go to diffution..??

non-destructive means the antenna diode won't be destructed by those small currents from draining-off antenna charges.

The charges captured by the metal antennas are drained-off from metal via contact to diffusion, and via the antenna diode to well resp. substrate.
Consider all silicon areas are connected to GND during the fabrication processes.
