Method of fabricating silicided LDD transistor

摘要

A gate-drain overlapped device, comprising: a first conductive type substrate; a gate insulating film formed on the substrate; a gate comprising a gate conductive line patterned on the gate insulating film, and a conductive layer coated on the gate conductive line and extending to a predetermined length on the gate insulating film; and a drain/source region comprising a second conductive type low density diffusion region in the substrate below the extending area of the conductive layer and a second conductive type high density diffusion region in contact with the low density diffusion region in the substrate, which is significantly improved in the resistance of a polysilicon gate conductive line and in uniform electrical properties.
