Abstract

A contact forming method of a semiconductor device is disclosed, in which a pad polysilicon layer is formed at an active region of a cell array, thereafter an upper portion of a gate is opened when a spacer of a NMOS transistor region is formed. And at the same time a gate capping insulating layer of the cell array region, the active region of the NMOS transistor and the gate node contact region remains at a predetermined thickness by etching the spacer. And then, by performing an ion implantation procedure on the entire surface, the direct pad polysilicon layer and the buried pad polysilicon layer are simultaneously ion-implanted.
