摘要:
A method for fabricating a short channel field-effect transistor is presented. A sublithographic gate sacrificial layer is formed, as are spacers at the side walls of the gate sacrificial layer. The gate sacrificial layer is removed to form a gate recess and a gate dielectric and a control layer are formed in the gate recess. The result is a short channel field-effect transistor with minimal fluctuations in the critical dimensions in a range below 100 nanometers.
