Abstract
Methods to form low-k dielectric materials for use as intermetal dielectrics in multilevel interconnect systems, along with their chemical and physical properties, are provided. The deposition techniques described include PECVD, PEALD, and ALD processes where the precursors such as TEOS and MDEOS may provide the requisite O-atoms and Ogas may not be used as one of the reactants. The deposition techniques described further include PECVD, PEALD, and ALD processes where Ogas may be used and, along with the Ogas, precursors containing embedded Si—O—Si bonds, such as (CHO)—Si—O—Si—(CHO)) and (CH)—Si—O—Si—(CH)may be used.
