ABSTRACT:
This invention relates to a method and resulting structure, wherein a DRAM may be fabricated by using silicon midgap materials for transistor gate electrodes, thereby improving refresh characteristics of access transistors. The threshold voltage may be set with reduced substrate doping requirements. Current leakage is improved by this process as well.
