摘要:
The present invention relates to thin films suitable as dielectrics in integrated circuits and for other similar applications and to methods for the production thereof. In particular, the invention concerns thin films comprising at least partially cross-linked siloxane structures obtainable by hydrolysis of one or more silicon compounds of the general formula R1—R2—Si—(X1)3, wherein X1 is a leaving group, R2 is a cycloalkyl having from 3 to 16 carbon atoms, an aryl having from 5 to 18 carbon atoms or a polycyclic alkyl group having from 7 to 16 carbon atoms, and R1 is a substituent of R2 selected from alkyl groups having from 1 to 4 carbon atoms, alkenyl groups having from 2 to 5 carbon atoms, alkynyl groups having from 2 to 5 carbon atoms, and aromatic groups having 5 or 6 carbon atoms, each of said groups being optionally substituted, and Cl and F.
摘要:
A thin film comprising a composition obtained by polymerizing a monomer having the formula I: wherein: R1 is a hydrolysable group, R2 is a polarizability reducing organic group, and R3 is a bridging hydrocarbon group, to form a siloxane material. The invention also concerns methods for producing the thin films. The thin film can be used a low k dielectric in integrated circuit devices. The novel dielectric materials have excellent properties of planarization resulting in good local and global planarity on top a semiconductor substrate topography, which reduces or eliminates the need for chemical mechanical planarization after dielectric and oxide liner deposition.
