Mobility Variation Due to Interface Trap Generation in Plasma Oxynitrided PMOS Devices
30 Jun 2008  Online Presentations  Contributor(s): Ahmad Ehteshamul Islam, Souvik Mahapatra, Muhammad A. Alam
Mobility degradation due to generation of interface
traps, Δµeff(NIT), is a wellknown phenomenon that has been
theoretically interpreted by several mobility models. Based on
these analysis, there is a general perception that Δµeff(NIT) is
relatively insignificant (compared to Δµeff due to …
