Simplified method of fabricating lightly doped drain insulated gate
field effect transistors
摘要:
A lightly doped drain in an IGFET is provided by fabricating the transistor in a epitaxial layer lightly doped in the conductivity type of the channel for the device. The laterally reduced dopant concentration of the drain, and a lightly doped source if desired, is provided by leaving portions of the epitaxial layer unmodified.
