  • Publication number: 20080012074
    Abstract: Traditionally, sol-gel silicates have been reported as being high temperature processable at 400 C to give reasonably dense films that showed good leakage current densities (<5×10?8 A/cm2). Recently we have discovered that we are able to prepare films from particular combinations of sol-gel silicate precursors that cure at 135° C. to 250° C. and give good leakage current density values (9×10?9 A/cm2 to 1×10?10 A/cm2) as well, despite the decrease in processing temperatures. These are some of the first examples of silicates being cured at lower temperatures where the leakage current density is sufficient low to be used as low temperature processed or solution processable or printable gate dielectrics for flexible or lightweight thin film transistors. These formulations may also be used in the planarization of stainless steel foils for thin film transistors and other electronic devices.

  • Publication number: 20070299176
    Abstract: A photodefinable, organosilicate material having a dielectric constant (?) 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.

  • Publication number: 20060013780
    Abstract: 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 ?-D-glucopyranosyl, ?-D-glucopyranosyl, or ?-D-galactopyranosyl.
