  • Patent number: 7892710
    Abstract: A method and article of manufacture for three-dimensional structures having micron dimensions includes coating a substrate with layers of photo resist. Each layer of photo resist is exposed with its own two-dimensional mask defining one slice of an object. Subsequent layers of photo resist are exposed with different patterns. Once all layers have been fabricated and exposed to identify two-dimensional features for the layer, the multiple layers are developed to removed photo resist which has not been exposed. The layered structure represents a three-dimensional object where the depth dimension is defined by the photo resist layer thickness. By decreasing the wavelength of the light exposure, it is possible to confine exposure to a single layer of photo resist.

  • Patent number: 7175967
    Abstract: Positive-working imageable elements are prepared by providing a first layer and second layers onto a substrate. Both layers include the same or different radiation absorbing compounds dispersed within different polymeric binders. After both layers are dried, they are heat treated at from about 40 to about 90° C. for at least 4 hours under conditions that inhibit the removal of moisture from the dried first and second layers. This method of preparation provides elements with improved imaging speed and good shelf life.

  • Patent number: 7163770
    Abstract: A positive-working imageable element comprises inner and outer layers and a radiation absorbing compound such as an IR absorbing dye. The inner layer includes a first polymeric material. The ink receptive outer layer includes a second polymeric binder comprising a polymer backbone and an —X—C(?T)—NR—S(?O)2— moiety that is attached to the polymer backbone, wherein —X— is an oxy or —NR?— group, T is O or S, R and R? are independently hydrogen, halo, or an alkyl group having 1 to 6 carbon atoms. After thermal imaging, the element can be developed using an alkaline developer. Use of the particular second polymeric binder reduces sludging in the developer. Its dissolution rate in the developer is slow enough to resist developer attack in the non-imaged areas of the outer layer but rapid enough for the second polymeric binder to be quickly loosened from imaged areas and kept suspended or dissolved for a considerable time.

  • Patent number: 7141348
    Abstract: This invention discloses a releasable adhesion layer having good adhesion during high temperature fabrication process in the absence of light, and delaminating at a lower temperature in the presence of light. One embodiment of this invention is a film of polymer whose thermal decomposition temperature changes drastically upon photoexposure. These materials, prior to photoexposure, can withstand temperatures in the range of approximately 200° C. to 300° C. without decomposition, yet decompose at around 100° C. with photoexposure. The releasable adhesion layer can be used in a thermal transfer element, sandwiching a donor substrate and a transfer layer having a plurality of multicomponent transfer units. In the absence of light, the releasable adhesion layer can sustain high temperature processing of these multicomponent transfer units. By photoexposing according to a pattern, the photoexposed multicomponent transfer units can be selectively released at a low temperature to transfer to a receptor.
