To form a substantially closed void between two structures on a substrate, a flowable liquid dielectric material is deposited to fill partially the space between the structures, and a surface is placed to bridge and substantially close the space between the structures. The substrate is then inverted whilst maintaining the bridge and the deposited material is allowed to flow down to be substantially supported by the surface. The material is set in its substantially supported position, and the surface is removed.

Method of forming a substantially closed void

A semiconductor device includes a low dielectric constant insulating film exhibiting an Si&#x2014;H Fourier Transform Infrared (FTIR) doublet defined by a first and a second peak, wherein the first peak is located at a higher wave number than the second peak, and wherein the ratio of the first peak to the second peak is greater than unity. A method of producing such a semiconductor device includes depositing a dielectric layer over a substrate and treating the dielectric layer in a hydrogen containing plasma such that the dielectric layer exhibits an Si&#x2014;H Fourier Transform Infrared (FTIR) doublet defined by a first and a second peak, wherein the first peak is located at a higher wave number than the second peak, and wherein the ratio of the first peak to the second peak is greater than unity.
