US Classification:

134/001100, 118/719000, 118/726000, 438/905000

Abstract:

A Process Module (“PM”) is designed to facilitate Transport Polymerization (“TP”) of precursors that are useful for preparations of low Dielectric Constant (“∈”) films. The PM consists primarily of a Material Delivery System (“MDS”) with a high temperature Vapor Phase Controller (“VFC”), a TP Reactor, a Treatment Chamber, a Deposition Chamber and a Pumping System. The PM is designed to facilitate TP for new precursors and for film deposition and stabilization processes.

US Classification:

422/138000, 422/198000, 422/134000, 422/206000

Abstract:

A multi-stage transport polymerization (“TP”) reactor useful for making a thin film for the fabrication of integrated circuits. One TP reactor has two distinct heating zones that facilitate the cracking of specific precursor materials. The multi-stage reactor comprises a first low temperature heating zone that heats incoming precursor materials to a temperature that is lower than the “cracking” temperature of the precursor. The second heating zone is maintained at a temperature useful for breaking the chemical bonds of a desired leaving groups in the selected precursor. Specialized heating bodies, which transfer heat to the precursor material in the low and high temperature zones, are used as elements of the invention that can simultaneously decrease the total volume and increase the inside surface area of the TP reactor. Chemistries of precursors used in the multi-stage reactor are also provided.

US Classification:

118/724000, 427/457000, 427/508000

Abstract:

A semiconductor equipment that is useful for the fabrication of integrated circuits (“IC”). More specifically, this invention relates to a “reactive-reactor” for a transport polymerization (“TP”) process module, wherein the process module is useful for the deposition of low dielectric (“ ”) thin films in IC manufacture. The reactive-reactor has reactive metal interior surfaces for effective conversion of precursors to intermediates. The resultant reaction products of the precursor and the interior surface material of the reactive-reactor are very stable, and do not cause metallic contamination of the semiconductors. The reactive-reactor of this invention is also equipped with Reactor Re-generating capacity to restore the reactive metal interior surfaces.
