Patent number: 7205025Abstract: In drying a coating liquid such as a resist applied to a substrate under reduced pressure, a coating film in a peripheral portion tends to lose good shape regardless of duration of a drying period, and it is difficult to set an appropriate exhaust flow rate. After the substrate is loaded in an airtight container, a pressure is reduced from atmospheric pressure to a pressure slightly higher than the vapor pressure of a solvent, for example. Then, the solvent actively evaporates from the coating liquid. Here, evacuation is performed initially based on a first flow rate set value Q1, and thereafter, it is performed based on a second flow rate set value larger than Q1. Rounding of the surface in the peripheral portion is corrected by evacuation based on Q1, and more active evaporation of a solvent component is attained by switching to Q2.Type: GrantFiled: August 29, 2005Date of Patent: April 17, 2007Assignee: Tokyo Electron LimitedInventors: Shinji Kobayashi, Takahiro Kitano, Shinichi Sugimoto

The repositionable dry erasable markerboard is made of a second layer, comprising a paper layer, with a first layer, comprising a dry erasable layer applied to the upper surface of the second layer, and a third layer, comprising a pressure sensitive adhesive layer, applied to the lower surface of the second layer. The dry erasable first layer may be either a coating cured under the presence of a nitrogen blanket or a film. The pressure sensitive adhesive of the third layer may be applied to the entire surface of the second layer or selectively zone-coated. The pressure sensitive adhesive of the third layer may be covered with a fourth layer, comprising a removable liner. The paper second layer may be coated and/or printed. The repositionable dry erasable markerboard is flexible and may be rolled into a tube.Type: GrantFiled: April 16, 2004Date of Patent: April 12, 2005Assignee: InVision Enterprises, Inc.Inventors: Mark A Meccia, Gregg A Steliga

Patent number: 6875466Abstract: The wafer coated with the resist is deliberately placed in the vapor before being transferred to an aligner that exposes the resist on the wafer, the vapor, for example, the moisture, uniformly adheres onto the resist on the wafer. As a result, the substrate can uniformly be exposed in the following exposing process, and the uniformity of the line width and the like can be improved.Type: GrantFiled: November 21, 2002Date of Patent: April 5, 2005Assignee: Tokyo Electron LimitedInventors: Hidefumi Matsui, Junichi Kitano

Patent number: 6875472Abstract: A system and method for applying a material for improving the adhesion between the surface of thermoplastic polyolefin (TPO) elements and a coating applied thereto is disclosed. The system comprises the mixing of an adhesion promoter with de-ionized water and applying it to the surface of the TPO elements to be coated. Preferably, the application occurs in an atmospherically controlled enclosure. The application of the adhesion promoter is preferably accomplished by distributing the mixture over the TPO elements through a series of nozzles. Multiple parameters of the application system may be monitored and regulated. Upon completion of the application process, the treated TPO elements are preferably dried in an oven, leaving a thin layer of adhesion promoter over the surface thereof.Type: GrantFiled: September 30, 2003Date of Patent: April 5, 2005Assignee: Honda Motor Co., Ltd.Inventors: Shubho Bhattacharya, Laura McBride, Yoshihiro Yamamoto, Shojiro Takeuchi, Saul Gonzalez Gutierrez

Patent number: 6866887Abstract: Electro-optic structures are constructed by spin coating water based emulsions or solvent based sensor materials, preferably a solvent-based polymer dispersed liquid crystal (PDLC), onto a substrate under conditions of controlled solvent evaporation. In a particular process, the uniformity of the PDLC coating is achieved by 1) spin coating in a semi-sealed chamber, 2) “converting” a square substrate into round substrate by using a fixture; 3) providing a controllable distance between the substrate and a spin coater top cover; and 4) providing a controllable solvent evaporation rate.Type: GrantFiled: October 14, 2003Date of Patent: March 15, 2005Assignee: Photon Dynamics, Inc.Inventors: Xianhai Chen, Alexander Nagy

Patent number: 6849305Abstract: 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: GrantFiled: October 4, 2002Date of Patent: February 1, 2005Assignee: EKC Technology, Inc.Inventors: Juan-Pablo Bravo-Vasquez, Ross H.

Patent number: 6844027Abstract: Systems and methods are described for environmental exchange control for a polymer on a wafer surface. An apparatus for controlling an exchange between an environment and a polymer on a surface of a wafer located in the environment includes: a chamber adapted to hold the wafer, define the environment, and maintain the polymer in an adjacent relationship with the environment; and a heater coupled to the chamber. A method for improving performance of a spin-on material includes: forming the spin-on material on a surface of a wafer; then locating the spin-on material in an environment so that said environment is adjacent said spin-on material; and then controlling an exchange between the spin-on material and said environment. The systems and methods provide advantages because inappropriate deprotection is mitigated by careful control of the environmental temperature and environmental species partial pressures (e.g. relative humidity).Type: GrantFiled: May 2, 2000Date of Patent: January 18, 2005Assignee: ASML Holding N.V.Inventors: Emir Gurer, Ed C.
