Abstract

The invention provides a method for manufacturing a transistor having a low leakage current. In general, spacers must be formed to isolate a gate from a subsequently-formed drain, thereby reducing a leakage current. In the invention, the spacers are formed on the vertical sides of the gate by using a selective deposition process. Therefore, the method for manufacturing a transistor having a low leakage current according to the invention not only constitutes a simplified process, but also controls the widths of the spacers precisely, so that the leakage current of the transistor can be greatly decreased.
