Webments, particularly self-alignment of refractory gate and ohmic contacts, very low thermal budget, extensive use of RIE and an entirely lift-off free process in the front end. Our process is based on a contact-first, gate-last flow developed for self-aligned planar InGaAs Quantum-Well MOSFETs that has yielded record gm values [12]. WebDec 1, 2005 · Self aligned silicides (salicides) are used for logic ULSI devices ( Fig. 1 (a)) to reduce sheet resistance and to achieve low contact resistance on gate, source (S) and drain (D) areas. S/D contacts are borderless to the silicide and the contact-resistance is not critical due to metal/metal (i.e., W/silicide) contacts.
