Abstract
A method of manufacturing a transistor having LDD regions in which the source and drain regions are formed by implanting ions through a photoresist layer at an energy of 1 MeV and greater and the LDD regions are formed by low energy ion implantation after the oxide layer is removed from the active region and the gate. In a second embodiment, the source and drain regions are formed without a photoresist layer by ion implantation and the LDD regions are formed by low energy ion implantation after the oxide layer is removed from the active region and the gate.
