  • Patent number: 7851121
    Abstract: There is provided a photosensitive composition including a polyimide or polyimide precursor. The polyimide and polyimide precursor of the present invention includes a group of a first acid-cleavable group, a first base-cleavable group or a first thermally-cleavable group, and another group of a hydrophilic group, or a protected hydrophilic group by a second acid-cleavable group, a second base-cleavable group, or a crosslinkable group.

  • Publication number: 20100216070
    Abstract: Photosensitive polyimide compositions include a photosensitive additive and a polymer comprising a repeating unit represented by the following formula (I): wherein R1 comprises an aliphatic group, an alicyclic group, an aromatic group, a heterocyclic group, or combinations thereof, R2 comprises an aliphatic group, an alicyclic group, an aromatic group, a heterocyclic group, or combinations thereof, R3 represents hydrogen or an organic group comprising a hydrophilic group, an acid-cleavable group, a base-cleavable group, a cross-linkable group, or combinations thereof, and h represents an integer of 1 or more. The photosensitive compositions may be formed by combining a precursor polymer with a processing solvent, followed by a relatively low-temperature cyclization process in which the precursor polymer is converted to the final polymer. The resulting polyimide may be separated from the solution and purified. It may then be combined with a casting solvent and a photosensitive additive.

  • Publication number: 20100009290
    Abstract: Photosensitive polybenzoxazine compositions include a photosensitive additive such as an o-diazoquinone and a polymer comprising a repeating unit represented by the following formula (I) wherein R1 comprises an aliphatic group, an alicyclic group, an aromatic group, a heterocyclic group, or combinations thereof, R2 comprises an aliphatic group, an alicyclic group, an aromatic group, a heterocyclic group, or combinations thereof, R4 comprises a hydrophilic group, a hydrophilic group protected by an acid-cleavable group, a hydrophilic group protected by a base-cleavable group, a cross-linkable group, or combinations thereof, and i represents an integer of 1 or more. The photosensitive compositions may be formed by combining a precursor polymer with a photosensitive additive and a solvent, patterning the precursor polymer, and heating the precursor polymer at a thermal processing temperature in a range of from about 180° C. to about 300° C. to convert the precursor polymer into the final polymer.

  • Publication number: 20070114401
    Abstract: A device for sculpting a substrate includes a vertically displaceable probe having a nano-scale dimensioned probe tip. A displacement mechanism is configured to adjust a vertical displacement between the probe tip and the substrate. A heating mechanism selectively heats the probe tip to a preselected temperature that is sufficient to cause a portion of the substrate in contact with the probe tip to decompose.

  • Publication number: 20040180292
    Abstract: The present invention relates generally to a method and apparatus for converting a precursor material, preferably organometallic, to a film, preferably metal-containing, that is adherent to at least a portion of a substrate. Both method and apparatus include a pre-conversion step or section, and a step or section for substantial conversion of a portion of material from the pre-conversion step or section into the form of a predetermined pattern, wherein this substantial conversion results in a metal-containing patterned layer on the substrate.
