摘要： A dynamic random access memory (DRAM) cell comprising a deep trench storage capacitor having an active transistor device partially disposed on a side wall of the trench. The side wall is aligned to a first crystallographic plane having a crystallographic orientation along a single crystal axis. A process for manufacturing such a DRAM cell comprises: (a) forming a deep trench in a substrate, (b) forming a faceted crystal region along the trench side wall having a single crystallographic orientation, and (c) forming a transistor device partially disposed on the faceted crystal region in the side wall. The faceted crystal region may be formed by growing an oxide collar, such as by local thermal oxidation under oxidation conditions selected to promote a higher oxidation rate along a first family of crystallographic axes than along a second family of crystallographic axes.
