摘要 |
The present invention relates to a method of manufacturing a MOS transistor, including the steps of delimiting, using a first resist mask N-type, drain and source implantation areas; removing the first mask and diffusing the implanted dopant; annealing, so that a thicker oxide forms above the source and drain regions than above the central gate insulation area; forming a polysilicon finger above the central gate insulation portion to form the gate of the MOS transistor; and performing a second source/drain implantation.
