摘要:
To provide a method for forming insulating thin films that can induce condensation of silanol and dehydration to a high degree at or near ambient pressure. An interlevel dielectric layer is formed on a semiconductor substrate by coating hydrogen silsesquioxane resin onto the substrate and curing the hydrogen silsesquioxane resin to produce an interlevel dielectric layer. This interlevel dielectric layer is then heated at a pressure from 1 to 1,000 torr at a temperature from 150 to 550° C.
摘要:
A method for forming thin films on substrates wherein the films are produced by applying a solution of an electrically insulating, heat-curing resin onto the substrate, evaporating the solvent and exposing the resin to high energy radiation to cure the resin. The resin solution contains a substance selected from solvents and gas generating additives that causes the dedensification of the film during the cure of the resin. This results in a film having a dielectric constant of below 2.7. A semiconductor device is also disclosed as having an interconnect structure including at least one electrically conductive layer with an interposed insulating layer having a dielectric constant of less than 2.7 wherein the insulating layer is produced by the method described above.
