Abstract:
A method of fabricating a self-aligned-contact, wherein a gate and a spacer are set on a source/drain region on a semiconductor substrate, said method comprising the steps of:forming a first dielectric layer and a second dielectric layer on the gate, the source/drain region, the first spacer, and the semiconductor substrate;patterning the second dielectric layer using the first dielectric layer as a stop layer;removing part of the first dielectric layer and the first spacer using the second dielectric layer as a mask to form a self-align-contact opening exposing the source/drain region a sidewall of the gate;forming a second spacer on the exposed sidewall of the gate, wherein the width of the second spacer is narrower than the width of the first spacer; andforming a conductive layer in the self-align-contact opening.
