PMOS Device Performance Improvement by using Buried Contact Implants
An ultra-low energy high dose B-based implant was processed after source and drain region formedand before metal sillicide contact formed for PMOS devices.B beam-line (BL) implant and plasma doping (PLAD) using either B2H6 or BF3 gases were utilized for this process.PMOS device performance showed significant improvements,including-70 percent lower contact resistances,similar threshold and sub-threshold characteristics,and-15 percent higher drive currents without degrading off current.PLAD is preferred on this application because of its much higher throughput in this process regime.
