Publication number: 20030059544Abstract: The invention is directed to a photoresist-free method for depositing films composed of metals, such as copper or silica, or their oxides from metal complexes. More specifically, the method involves applying an amorphous film of a metal complex to a substrate. The metal complexes have a metal and a photo-degradable ligand. A preferred ligand is acac or alkyl-acac, expecially in combination with acetate ligands. These films, upon, for example, thermal, photochemical or electron beam irradiation may be converted to the metal or its oxides. By using either directed light or electron beams, this may lead to a patterned metal or metal oxide film in a single step. Low temperature baking may be used to remove residual organics from the deposited film. If silica is the metal, the deposited film has excellent smoothness and dielectric properties.Type: ApplicationFiled: October 4, 2002Publication date: March 27, 2003Inventors: Juan-Pablo Bravo-Vasquez, Ross H.

Patent number: 6406832Abstract: A method for fabricating a rib on a glass substrate includes steps of printing a first paste layer on the glass substrate, printing a second paste layer onto a first predetermined area of the first paste layer and the second paste layer having a hardener, activating the hardener of the second paste layer to harden the second paste layer, performing a stripping process to remove a portion of the first paste layer uncovered by the hardened second paste layer, and sintering the remaining first paste layer and the second paste layer to form the ribs. The first paste layer is formed by a solid printing process and the second paste layer is formed by a screen printing process. The second paste layer is a rib material having a photo-active hardener, such as polyvinyl cinnamate. The hardener of the second paste layer is activated by an exposure process. Finally, the hardener is removed from the second paste layer in the sintering process and the first paste layer is fused to the second paste layer.Type: GrantFiled: April 4, 2000Date of Patent: June 18, 2002Assignee: AU Optronics Corp.Inventor: Chung-Wang Chou

Publication number: 20020064616Abstract: A range of damage and wear-susceptible articles, including such as drinkware and flatware, and heat-susceptible articles, have a tough, protective plastic coating applied in sealing, protective relation with a surface portion. The protective coating may hermetically seal underlying decorative material, including toxic materials. Digital ink jet printing may be applied directly or by transfer, including pad transfer. A plastic undercoating incorporating an adhesion promoting additive may first be applied by DIJ printing or by flow coating. The impact resistance of drinking glasses can be improved ten-fold with a hard, visually undetectible 5-mil outer coating selected from polyesters and other polymers, polyurethanes and acrylates having the desired visual, toughness and bonding characteristics. With u.v. curing, high speed economic automated line production, the process is applicable to a wide range of articles.Type: ApplicationFiled: January 17, 2002Publication date: May 30, 2002Inventor: Henry Sawatsky

Publication number: 20020039624Abstract: Barrier ribs are formed on a back plate moved while a rib material is delivered thereto from a nozzle. Immediately after the rib material is delivered from the nozzle to the back plate, the rib material is irradiated with light to promote curing of the rib material. By promoting curing of the rib material with light emitted immediately after delivery of the rib material, the rib material delivered linearly to the back plate is maintained in shape. The rib forming process is thereby simplified to form barrier ribs with high quality and high accuracy. The rib material is used efficiently to achieve low cost. Besides, the barrier ribs may be formed to have a high aspect ratio.Type: ApplicationFiled: October 4, 2001Publication date: April 4, 2002Applicant: Dainippon Screen Mfg.
