Patent number: 7090890Abstract: The methods of this invention involve modification of the properties of an organic film after it has been deposited by either adding new components into it from its top or bottom surface, or by causing components to leave the film from its top or bottom surface. In the examples of these methods, the emitting color of light-emitting diodes are modified based on doped polymers by locally introducing dopants causing different color emission into the film by local application of a solution containing the desired dopant to the film surface (by ink jet printing, screen printing, local droplet application, etc.). This overcomes difficulties encountered with the direct patterning of three separately formed organic layers (each which uniformly coats an entire surface when formed) into regions for separate R, G, and B devices due to the sensitivities of the organic materials to chemicals typically used with conventional patterning technologies.Type: GrantFiled: April 12, 1999Date of Patent: August 15, 2006Assignee: The Trustees of Princeton UniversityInventors: James C.

Patent number: 7022377Abstract: A method of producing porous polyimide resin that enables pores to be formed in a precursor of polyimide resin, with its form of microphase-separated structure wherein a dispersive compound is dispersed in the precursor of polyimide resin being kept unchanged, so as to provide significantly reduced dielectric constant and also provide improvement in mechanical strength and heat resistance, and the porous polyimide resin produced in the same producing method. A coating comprising porous polyimide resin is formed by applying resin solution comprising a precursor of polyimide resin and a dispersive compound and then drying a solvent, to form a coating in which the dispersive compound is dispersed in the precursor of polyimide resin; extracting the dispersive compound from the coating for removal to make the precursor of the polyimide resin porous; and imidizing the coating after preheated in a temperature range of 190–250° C.Type: GrantFiled: July 10, 2002Date of Patent: April 4, 2006Assignee: Nitto Denko CorporationInventors: Mitsuhiro Kanada, Takahiro Fukuoka, Naotaka Kinjou

Patent number: 6989172Abstract: A method of coating a substrate comprises the steps of: (a) providing a substrate in an enclosed vessel, the substrate having a surface portion; (b) at least partially filling the enclosed vessel with a first supercritical fluid so that said first supercritical fluid contacts the surface portion, with the first supercritical fluid carrying or containing a coating component; then (c) adding a separate compressed gas atmosphere to the reaction vessel so that a boundary is formed between the first supercritical fluid and the separate compressed gas atmosphere, said separate compressed gas atmosphere having a density less than said first supercritical fluid; and then (d) displacing said first supercritical fluid from said vessel by continuing adding said separate compressed gas atmosphere to said vessel so that said boundary moves across said surface portion and a thin film of coating component is deposited on said microelectronic substrate.Type: GrantFiled: October 8, 2003Date of Patent: January 24, 2006Assignee: Micell Technologies, Inc.Inventors: James P. DeYoung, James B. McClain, Stephen M. Gross, Doug Taylor, Mark I. Wagner, David Brainard

Patent number: 6899924Abstract: An undercoat composition comprises a film-forming synthetic resin and contains a non-volatile acidic aromatic polar organic compound in free acid or salt form, which compound facilitates the removal by a stripping composition of a top coat paint which is subsequently applied over the undercoat. A top coat composition for applying as the outer coating on a substrate comprises a film-forming synthetic resin having functional groups and a curing agent for crosslinking the synthetic resin and contains a non-volatile acidic aromatic polar organic compound in free acid or salt form, which compound facilitates the removal of the cured top coat by a stripping composition from a cured undercoat of similar composition which does not contain the said acidic aromatic polar organic compound.Type: GrantFiled: March 16, 1999Date of Patent: May 31, 2005Assignee: PRC-DeSoto International, Inc.Inventors: Peter Carson, Rodney Ralph Brooks, Michael Fowler
