Popis: Novel Al/sub 2/O/sub 3/ process was developed in order to extend the applicability of reliable SIS and MIS Al/sub 2/O/sub 3/ capacitors as well as Al/sub 2/O/sub 3/ EBL for a MIM capacitor. By applying ALD process utilizing a smart growth mechanism, electrical and interfacial properties of Al/sub 2/O/sub 3/ film were surprisingly improved. The SIS and MIS Al/sub 2/O/sub 3/ capacitor technologies with ultra-low thermal budget were confirmed by producing fully working 1 Gbit DRAM with design rule of 0.15 and 0.13 /spl mu/m, respectively. Moreover, Al/sub 2/O/sub 3/ EBL for a MIM capacitor was successfully used to preserve the excellent dielectric characteristics for the application of DRAM with design-rule of 0.10 /spl mu/m, and beyond.
