Abstract

The invention includes semiconductor structures having buried silicide-containing bitlines. Vertical surround gate transistor structures can be formed over the bitlines. The surround gate transistor structures can be incorporated into memory devices, such as, for example, DRAM devices. The invention can be utilized for forming 4F2 DRAM devices.
