pocket implant

Pocket implants are used to avoid Punch through effects in short-channel devices. they are heavily doped (unlike LDD) small regions of substrate at the edges of drain and source regions to avoid depletion regions of drain and Source to pronounce into channel

depletion regions of drain and Source to pronounce into channel is also called drain-induced barrier effect(DIBL)?
 

pocket implant?

DIBL is the effect due to the High Strongly inverted and high Vds voltage.

This punch through effect is without them
