Abstract
A method of fabricating FETs to reduce parasitics. Contact is made to the source and drain regions through a polycrystalline silicon runner which is aligned with the edge of the gate electrode. This is accomplished by providing a layer such as palladium over the gate electrode and depositing the polycrystalline silicon layer over the device. The polycrystalline silicon and palladium form a silicide which is then selectively etched leaving the remaining polycrystalline silicon aligned with the gate.
