Abstract: The present invention provides a metal contact of SiGe combined with cobalt silicide and cobalt. The contact resistance is greatly lowered due to both the low Schottky Barrier Height of SiGe and the low sheet resistance of cobalt silicide. The cobalt layer can serve as a glue layer and diffusion barrier layer. Thus, no additional glue layer or diffusion barrier layer needs to be formed. Moreover, the metal contact of the present invention can be integrated with a DRAM by a hybrid contact method. Implantation contact is used in pFET regions and diffusion contact is used in nFET regions. This can reduce mask steps and production costs.

Abstract: The present invention discloses structure and manufacturing method of binary nitride-oxide (NO) dielectric node for deep trench based DRAM devices. In the present invention, a thin strained SiGe layer is deposited prior to poly deposition to modulate the chemical potential unbalance caused by work-function (WF) differences between buried plate and poly. The thin strained SiGe layer will lower the differences by its lower band-gap characteristics at the same doping level, thereby balancing the chemical potential despite of a different doping. The modulation of the chemical potential can be achieved by a proper control of a stochimetric x value. The optimized chemical potential will assure the reliability and robustness of the dielectric node, especially the binary NO dielectric node by suppressing asymmetric charging trapping and charge injection nature.
