A method for making a dual silicide or germanide semiconductor comprises steps of providing a semiconductor substrate, forming a gate, forming source/drain regions, forming a first silicide, reducing spacers thickness and forming a second silicide. Forming a gate comprises forming an insulating layer over the semiconductor substrate, and forming the gate over the insulating layer. Forming source/drain regions comprises forming lightly doped source/drain regions in the semiconductor substrate adjacent to the insulating layer, forming spacers adjacent to the gate and over part of the lightly doped source/drain regions, and forming heavily doped source/drain regions in the semiconductor substrate. The first silicide is formed on an exposed surface of lightly and heavily doped source/drain regions. The second silicide is formed on an exposed surface of lightly doped source/drain regions. A first germanide and second germanide may replace the first silicide and the second silicide.

Method for making dual silicide and germanide semiconductors

A method for forming a semiconductor structure having a deep sub-micron or nano scale line-width is disclosed. Structure consisting of multiple photoresist layers is first formed on the substrate, then patterned using adequate exposure energy and development condition so that the bottom photoresist layer is not developed while the first under-cut resist groove is formed on top of the bottom photoresist layer. Anisotropic etching is then performed at a proper angle to the normal of the substrate surface, and a second resist groove is formed by the anisotropic etching. Finally, the metal evaporation process and the lift-off process are carried out and the &#x393;-shaped metal gate with nano scale line-width can be formed.
