The specification and drawings present a new method, device and computer/software related product (e.g., a computer readable memory) are presented for realizing eDRAM strap formation in Fin FET device structures. Semiconductor on insulator (SOI) substrate comprising at least an insulator layer between a first semiconductor layer and a second semiconductor layer is provided. The (metal) strap formation is accomplished by depositing conductive layer on fins portion of the second semiconductor layer (Si) and a semiconductor material (polysilicon) in each DT capacitor extending to the second semiconductor layer. The metal strap is sealed by a nitride spacer to prevent the shorts between PWL and DT capacitors.
