Abstract:
Structures and methods for making vertical transistors in the Embedded Dynamic Random Access Memory (eDRAM) scheme are provided. A method includes: providing an SOI substrate with a buried insulator layer therein, forming a trench through the substrate, filling the trench with a first polysilicon material, and after filling the trench with the first polysilicon material, i) growing a second polysilicon material over the first polysilicon material and ii) epitaxially growing a doped layer over the SOI substrate, wherein the grown second polysilicon material and epitaxially grown doped layer form a basis for a strap merging the doped layer and the second polysilicon material.

Claim (Index 9):
The method according to  claim 8  further comprising:\n removing the second hardmask; and \n creating a shallow-trench isolation region in the recessed portion of the second doped layer, wherein the remaining portion of the second polysilicon material and the second doped layer form the strap, wherein the deposition of the second hardmask is such that it covers a suitable area such that when the second hardmask is removed the second hardmask enables a formation of the strap.
