Abstract:
1. A method of manufacturing a zero capacitance random access memory cell (ZRAM), comprising: forming a finFET on a substrate; and enhancing a storage capacitance of the finFET by one of adding a storage capacity to the finFET and altering a portion of the finFET after formation of a fin body of the finFET, wherein: the altering comprises segmenting the fin body by doping a lower portion of the finFET, and the doping the lower portion of the finFET includes depositing a borosilicate glass on a buried oxide layer, partially etching the borosilicate glass to expose an upper portion of the fin body, and subjecting the borosilicate glass to an annealing process which out diffuses boron into an adjacent portion of the fin body.
