Abstract:
A method for manufacturing a semiconductor device, comprising:providing at least two active devices over a substrate, each of the active devices includes a gate electrode provided over a gate oxide, a silicide formed over the gate electrode, a cap formed over the silicide, and a pair of spaced-apart diffused regions formed in the substrate; depositing a first layer of dielectric material over the substrate and active devices; providing a first photoresist over the first layer of dielectric material; defining and patterning the first photoresist; etching the first layer of dielectric material unmasked by the first photoresist to form a first opening, wherein the first opening exposes a first silicide of a first active device; removing the first photoresist; depositing a second layer of dielectric material over the first layer of dielectric material and in the first opening; providing a mask over the second layer of dielectric material; providing a second photoresist over the mask; defining and patterning the second photoresist; and forming a second opening and a third opening, wherein the second opening is aligned with the first opening and exposes the first silicide of the first active device, and the third opening exposes one of the pair of the spaced-apart diffused regions of a second active device.
