Abstract:
A method of forming a bit line gate structure of a dynamic random access memory (DRAM) includes the following steps. A polysilicon layer is formed on a substrate. A sacrificial layer is formed on the polysilicon layer. An implantation process is performed on the sacrificial layer and the polysilicon layer. The sacrificial layer is removed. A metal stack is formed on the polysilicon layer. The present invention also provides another method of forming a bit line gate structure of a dynamic random access memory (DRAM) including the following steps. A polysilicon layer is formed on a substrate. A plasma doping process is performed on a surface of the polysilicon layer. A metal stack is formed on the surface of the polysilicon layer.

Claim (Index 1):
A method of forming a bit line gate structure of a dynamic random access memory (DRAM), comprising:\n forming a polysilicon layer on a substrate; forming a sacrificial layer on the polysilicon layer; performing an implantation process on the sacrificial layer and the polysilicon layer, wherein the maximum implanting concentration of the polysilicon layer and the sacrificial layer implanted by the implantation process is at an interface of the polysilicon layer and the sacrificial layer; removing the sacrificial layer; and forming a metal stack on the polysilicon layer.
