Abstract
An integrated circuit device having non-linear active area pillars. More specifically, pillars are formed in a substrate such that sidewalls are exposed. The sidewalls of the pillars and the top surface of the pillars are covered with a gate oxide and a conductive layer to form a channel through the pillars. The pillars are patterned to form non-linear active area lines having angled segments. The conductive layer is patterned to form word lines that intersect the active area lines at the angled segments.
