Impact of the Gate and Fin Space Variation on Stress Modulation and FinFET Transistor Performance


Device scaling in advanced CMOS nodes is becoming more difficult due to patterning limitations and complex 3-D transistor integration schemes. This also makes the devices more sensitive to patterning variability. The presented study investigates the impact of poly pitch and fin pitch variability on stress-induced performance variation in 7nm FinFET transistors. Variations in critical dimension ... » read more

Stress-Related Local Layout Effects In FinFET Technology And Device Design Sensitivity


Abstract: "Transistor characteristics in advanced technology nodes are strongly impacted by devices design and process integration choices. Variation in the layout and pattern configuration in close proximity to the device often causes undesirable sensitivities known as Local Layout Effects (LLEs). One of the sensitivities is related to carrier mobility dependence on mechanical stress, modul... » read more
