    Abstract: A process for patterning thick film electrically functional patterns using a photosensitive polymer layer. A tacky photosensitive layer is applied onto a substrate surface. The photosensitive layer is imaged with a pattern using actinic radiation, the exposed areas of the photosensitive layer become hardened and non-tacky. A subsequent application of a thick film composition sheet will cause the thick film to adhere to the remaining tacky areas. Upon peeling the sheet, a thick film print pattern will be produced. This step is followed by a processing profile prescribed by the thick film composition used which results in a pattern having electrically functional properties. The invention also extends to a process wherein a thick film composition is recovered from a used sheet.

  • Patent number: 6562552
    Abstract: A method of manufacturing a panel assembly used to assemble a display panel intends to achieve an alignment-free between barrier ribs and a fluorescent layer and minimize the waste of a barrier rib material for cost reduction. On a support body 51 which is not a substrate, formed are a plurality of walls 281 through 283 made of a fluorescent material that are belt-shaped in plan view arranged in stripes, an electrode material layer a1, and a barrier rib material filling spaces between the walls. The support body 51 and a substrate 21 are coupled so that the barrier rib material faces the substrate. The walls 281 through 283, the electrode material layer a1 and the barrier rib material 291 are transferred in one step to the substrate 21, and thus a panel assembly 20 having barrier ribs 29, electrodes A and fluorescent layers 28R, 28G and 28B is obtained.

  • Patent number: 6558868
    Abstract: The present invention is for a method of fabricating a high aspect ratio, freestanding microstructure. The fabrication method modifies the exposure process for SU-8, an negative-acting, ultraviolet-sensitive photoresist used for microfabrication whereby a UV-absorbent glass substrate, chosen for complete absorption of UV radiation at 380 nanometers or less, is coated with a negative photoresist, exposed and developed according to standard practice. This UV absorbent glass enables the fabrication of cylindrical cavities in a negative photoresist microstructures that have aspect ratios of 8:1.
