  • Reliable low resistance strap for trench storage DRAM cell using selective epitaxy
    Patent number: 5923971
    Abstract: Strap resistance, surface strap shorts and wordline capacitance can be reduced by providing a selectively grown silicon strap which tapers away from spacer nitride and has less contact with spacer nitride. In addition the strap is optionally doped with an arsenic implant which reduces resistance.
