Mask development process for 2x nm node devices needs stringent CD uniformity and CD linearity. To evaluate and improve these CD qualities, we proposed to introduce electric-field-induced-development method into proximity gap suction development system (PGSD). It is the way to develop with applying electric potential to the metallic development nozzle to stimulate the movement of hydroxide ions. In this paper, we will report the effect of electric-field-induced-development method on CD uniformity and CD linearity.
