Super Planarizing Material For Trench And Via Arrays


As device design scales and becomes more complex, fine control of patterning and transfer steps is integral. Planarization of deep trenches and via arrays has always been a challenge. Aspect ratios continue to increase while critical dimensions shrink, and typical trench fill schemes are no longer able to meet the fill and planarization requirements. Traditional design of spin-on carbon (SOC) m... » read more
