Abstract
The degradation in MOS device characteristics as well as in their hot-electron injection immunity caused by ion-bombardment processes has been investigated. It has been found that neutral electron traps were generated due to the charging-up of the gate electrode during ion implantation. These neutral traps contribute to enhanced positive threshold shifts in the following hot-electron injection experiment. It has been demonstrated that such problems can be eliminated by grounding the gate electrode during ion implantation. Similar effects were also observed for a low-energy bias sputtering deposition process.
