Publication number: 20110052793Abstract: A method is provided for the determination a thickness error in a previously deposited layer using the reflection monitor signal of the currently-depositing layer. This thickness error is then used to compute corrections to the thickness of the currently-depositing layer and the next layer which corrects for the thickness error in the previous layer. The method is stable with respect to noise in the optical monitor signal. The technique is applicable for optical coating designs which are not necessarily quarter wave. The approach avoids the buildup of thickness errors from layer to layer and thus is applicable for very thick designs with many layers. Near the end of a currently depositing layer the monitor signal is used to fit the admittance of the base stack under the current layer. This establishes the parameters in an exact reflectance model used for the rate or thickness monitoring of the current layer.Type: ApplicationFiled: May 14, 2008Publication date: March 3, 2011Inventor: William H.

Publication number: 20080311283Abstract: An auxiliary layer is provided over a main surface of a sample, wherein the sample may be a semiconductor substrate. The auxiliary layer may have an essentially plane surface and is transparent or semi-transparent to an inspection radiation with a wave length between, for example, 193 and 800 nm. The sample coated with the auxiliary layer is inspected for defects in the sample via an imaging method that may use coherent radiation. After inspection, the auxiliary layer is removed. Dependent on the defect count, a process of manufacturing integrated circuits may be continued or the sample may be reworked or discarded.Type: ApplicationFiled: June 15, 2007Publication date: December 18, 2008Applicant: QIMONDA AGInventors: Ingo Brasack, Michael Goldberg, Kerstin Muehlstaedt

Patent number: 7449213Abstract: A phosphor paste is applied to inner surfaces of a cell. Then, a conveyer moves a substrate relative to a CCD camera at a constant speed. Simultaneously, two LEDs radiate visible light onto a portion, to be inspected, of the substrate. The visible light is light configured to have a wavelength so as to be able to prevent the phosphor of the phosphor paste from being excited and emitting light and reflected by a liquid surface of the phosphor paste to produce reflected light. Thereafter, the CCD camera captures an image of the phosphor paste and a data processor processes the received image data, and determines whether a phosphor layer formed by drying the phosphor paste will normally be formed, prior to formation of phosphor layer.Type: GrantFiled: July 3, 2003Date of Patent: November 11, 2008Assignee: Pioneer CorporationInventors: Shinji Yokono, Kazumasa Nishiwaki

Patent number: 7450233Abstract: A measuring device includes several sequentially disposed coating chambers for measuring optical properties of coated substrates. These coating chambers are separated from one another by partitioning walls, whose free ends are located closely above the substrate. The substrate is preferably a continuous film. By measuring the reflection, the transmission, etc. of the substrate between the individual coating chambers, it becomes possible to carry out measurements within only partially completed layer systems. This yields advantages for the technical operation control of the coating process.Type: GrantFiled: November 24, 2004Date of Patent: November 11, 2008Assignee: Applied Materials GmbH & Co.

Publication number: 20080124528Abstract: A printed electronic device and methods for determining the electrical value of the device. A dielectric material is contact printed on a substrate using a preset force. The substrate has a pressure sensitive material that is optically responsive in direct proportion to the amount of force imparted by the contact printing. The force of the contact printing causes the pressure sensitive material to form a pattern that is quantifiable to the amount of force. The pattern is then optically inspected and compared to sets of standards in order to quantify the amount of force that was used in printing. The thickness of the printed dielectric material is then calculated based on the quantified force by comparing to another set of standards. The electrical value of the printed material is calculated based on the calculated thickness of the printed dielectric material, the surface area of the printed dielectric material, and the dielectric constant of the dielectric material.Type: ApplicationFiled: November 29, 2006Publication date: May 29, 2008Applicant: MOTOROLA, INC.Inventors: Jerzy Wielgus, Daniel R.
