Patent number: 6451116Abstract: A method and apparatus is disclosed for sequential processing of integrated circuits, particularly for conductively passivating a contact pad with a material which resists formation of resistive oxides. In particular, a tank is divided into three compartments, each holding a different solution: a lower compartment and two upper compartments divided by a barrier, which extends across and partway down the tank. The solutions have different densities and therefore separate into different layers. In the illustrated embodiment, integrated circuits with patterned contact pads are passed through one of the upper compartments, in which oxide is removed from the contact pads. Continuing downward into the lower compartment and laterally beneath the barrier, a protective layer is selectively formed on the insulating layer surrounding the contact pads. As the integrated circuits are moved upwardly into the second upper compartment, a conducting monomer selectively forms on the contact pads prior to any exposure to air.Type: GrantFiled: August 1, 2001Date of Patent: September 17, 2002Assignee: Micron Technology, Inc.Inventors: Tongbi Jiang, Li Li

Patent number: 4987851Abstract: An organic film forming apparatus includes a trough storing water therein and a work drive device for moving a work with respect to the trough. The surface of the water is partitioned by a rod into a first developing region on which a monomolecular film is developed and a second developing region on which no monomolecular film is developed. The work is moved by the device through the developed monomolecular film so as to adhere the film on the surface of the work. The device has a holding mechanism which has a holding portion engaged with the work, and which holds the work so that when the work passes through the developed monomolecular film, the holding portion is away from the film or passes through the film after almost the entire work passes through the film.Type: GrantFiled: December 30, 1988Date of Patent: January 29, 1991Assignee: Kabushiki Kaisha ToshibaInventors: Satoshi Yasuda, Shigeru Wakayama, Yoshiaki Tsukumo, Takashi Haraguchi, Syun Egusa

Patent number: 4645693Abstract: A barrier assembly for a Langmuir trough is arranged for a substrate to be carried automatically to-and-fro on a dipping head over a fixed barrier into monomolecular layers A, B on a common subphase so as to stack layers ABABAB . . . on the substrate. The layers A, B are confined by the barrier and two constant perimeter areas formed by a single flexible band passing over rollers. By adjusting the positions of bridges that carry some of the rollers, the confined areas can be contracted to compress the layers A, B. In an alternative mode the substrate receives a layer from layer A while a new layer B is being formed, the substrate then being transferred to layer B while a new layer A is being formed. This involves an oscillating rather than a rotating movement of the substrate.Type: GrantFiled: November 12, 1985Date of Patent: February 24, 1987Assignee: Vickers Public Limited CompanyInventors: Gareth G. Roberts, Brian Blackburn, Michael C. Petty, Brian Holcroft

By altering the position of another transverse part joining the two further longitudinal parts the area enclosed is varied by changing the length of the longitudinal part close to the first longitudinal part and altering the length of the longitudinal part further away by an amount such that the sum of the two altered lengths remains constant.Type: GrantFiled: November 12, 1985Date of Patent: February 17, 1987Assignee: Vickers Public Limited CompanyInventors: William A.

Patent number: 3965855Abstract: Method and apparatus to heat fix a heat fusible xerographic powder image to a final support material in which the powder image is first transferred to a final support material and the image-bearing support material then brought into contact with a bath of hot liquid metal for a period of time sufficient to fix the image to the support material. The temperature of the bath is maintained at a temperature high enough to fuse the image but below that at which the support material is damaged. The liquid metal bath has floating on it a layer of molten non-metal to prevent oxidating of the metal and to precoat the support material on its entry into the bath to prevent particles of the liquid metal from embedding in the support material. The relative high density of the molten metal acts as a wringer to keep the plasticized coating very thin when drawn out of the bath.This is a division of application Ser. No. 500,411 , filed Aug. 26, 1974.Type: GrantFiled: April 4, 1975Date of Patent: June 29, 1976Assignee: Xerox CorporationInventor: Ernest A. Weiler
