    Abstract: A new method for manufacturing an MOS transistor is applied in the deep submicron process. In this method, a polysilicon layer is mainly used to form a raised source/drain structure and self-alignment is achieved by means of a planarization process. This method can reduce short channel effects and the series impedance of the source/drain as well as accomplish the local interconnection of a circuit and planarization. Therefore, this method is very suitable for manufacturing devices in the deep submicron process.

    Abstract: A method for formation of both local innerconnection and silicidation of source/drain transistors using the deposition of a blanket silicon layer over the entire top surface of the transistors and selectively stripping of unwanted portions of the silicon layer is disclosed. The method includes the step of applying a photoresist mask to map out where the local interconnection and source/drain are to be located. The final recited step is to deposit a thin metal layer to provide for the silicidation to complete the transistor. The silicon layer that is deposited has a thickness of 20 to 300 millimeters, and the thin metal layer is either cobalt or titanium having a thickness of 10 millimeters to 100 millimeters.
