Abstract:
1. A method of manufacturing a spin transistor, comprising: forming an insulation layer on a substrate; forming a first contact window in the insulation layer; forming a doping area in the substrate via the first contact window, wherein the conductivity of the doping area is opposite to that of the substrate; forming a second contact window in the insulation layer; forming a magnetoresistive film on the insulation layer; forming a metal conductive layer on the insulation layer, the first contact window, the second contact window and the magnetoresistive film; and performing a lithography and etching processing on the metal conductive layer to define a first metal region located at the first contact window, a second metal region located at the second contact window, and a third metal region located on the magnetoresistive film, wherein the first metal region contacts the magnetoresistive film.
