摘要： In a method of forming a dual polysilicon gate of a semiconductor device, a polysilicon layer is formed on a substrate divided into an NMOS region and a PMOS region. Then, a p-type impurity is implanted in the PMOS region. A thermal annealing process is performed that causes generation of a compound material at a top surface of the polysilicon layer in the PMOS region as a result of bonding between the p-type impurity and the polysilicon layer. A cleaning process is then performed. During the cleaning process, the compound material decreases an etch rate in the PMOS region, so that a height of the polysilicon layer in the NMOS region is reduced relative to that of the polysilicon layer in the PMOS region. Accordingly, an intended range of a threshold voltage can be obtained by blocking the p-type impurity in the PMOS region from penetrating into a gate insulation layer. Also, by maintaining an increased height of a gate transmission material in the cell region, a resistance increase is thereby prevented.

摘要： Embodiments of the invention provide a semiconductor device and a fabrication method for a semiconductor device that includes the processes of forming multiple gates on a silicon substrate, forming a gate spacer having a positive slope at the gate spacer edge, depositing a polysilicon layer on the silicon substrate between the gates, etching a portion of the polysilicon layer to form an opening exposing a portion of the silicon substrate, and forming an inter-insulation layer to the exposed portion of the silicon substrate to fill the opening. Using an annealing process applied to a layer in the gate spacer, the etch selectivity can be selectively controlled and consequently, the degree of slope at the gate spacer edge is predetermined.
