摘要:
A photodefinable, organosilicate material having a dielectric constant (κ) of 3.5 or below and a method for making and using same, for example, in an electronic device, is described herein. In one aspect, there is provided a composition for preparing a photodefinable material comprising: a silica source capable of being sol-gel processed and having a molar ratio of carbon to silicon within the silica source contained therein of at least 0.5 or greater; a photoactive compound; optionally a solvent; and water provided the composition contains 0.1% by weight or less of an added acid where the acid has a molecular weight of 500 or less.

A dense cleaning fluid for removing contaminants from a substrate and a method comprising same is disclosed herein. In one embodiment of the present invention, the dense cleaning fluid comprises a dense fluid and at least one acetylenic diol or acetylenic alcohol surfactant.
摘要:
Surfactant compositions containing compounds according to structure (I), and methods of making them, are disclosed. The compounds provide reduced dynamic and equilibrium surface tension, good solubility, moderate foaming, and good cleaning performance. The methods for making them involve reaction of N-(polyhydroxyalkyl)-alkylamines with dinitriles, dialdehydes, or acetals or hemiacetals of dialdehydes in the presence of hydrogen and a transition metal catalyst. In structure (I), x is an integer from about 1 to 12, R1 and R2 are independently C3-C30 linear alkyl, cyclic alkyl, branched alkyl, alkenyl, aryl, alkylaryl, alkoxyalkyl, and dialkylaminoalkyl; and R3 and R4 are independently hydrogen or a pyranosyl group such as α-D-glucopyranosyl, β-D-glucopyranosyl, or β-D-galactopyranosyl.
