Abstract:
Dielectric composite films characterized by a dielectric constant (k) of less than about 7 and having a density of at least about 2.5 g/cm 3  are deposited on partially fabricated semiconductor devices to serve as etch stop layers. The dielectric composite film in one embodiment includes Al, Si, and O and has a thickness of between about 10-100 Å. The dielectric composite film can reside between two layers of inter-layer dielectric, and may be in contact with metal layers. An apparatus for depositing such dielectric composite films includes a process chamber, a conduit for delivering an aluminum containing precursor to the process chamber, a second conduit for delivering a silicon-containing precursor to the process chamber and a controller having program instructions for depositing the dielectric composite film from these precursors, e.g., by reacting the precursors adsorbed to the substrate with an oxygen-containing species.

Claim (Index 1):
An apparatus for depositing a composite dielectric composite film on a semiconductor substrate, the apparatus comprising:\n (a) a process chamber having a support for the semiconductor substrate; (b) a first conduit configured for delivery of an aluminum-containing precursor to the process chamber; (c) a second conduit configured for delivery of a silicon-containing precursor to the process chamber; and (d) a controller comprising program instructions for causing a deposition of the dielectric composite film on the semiconductor substrate by including program instructions for causing the operations of:\n (i) providing an aluminum-containing precursor to the process chamber housing the semiconductor substrate through the first conduit and adsorbing the aluminum-containing precursor on a surface of the semiconductor substrate; \n (ii) after the aluminum-containing precursor has adsorbed in (i), purging and/or evacuating the process chamber; \n (iii) after purging and/or evacuation of the process chamber in (ii), providing a silicon-containing precursor to the process chamber through the second conduit and adsorbing the silicon-containing precursor on the surface of the semiconductor substrate; \n (iv) after the silicon-containing precursor has adsorbed in (iii), purging and/or evacuating the process chamber; and \n (v) after purging and/or evacuation of the process chamber in (iv), reacting the adsorbed aluminum-containing precursor and the silicon-containing precursor with an oxygen-containing species to form the dielectric composite film on the semiconductor substrate, wherein the dielectric composite film comprises Al\u2014O and Si\u2014O bonds.
