  • Method and device for screening out particles
    Publication number: 20090134073
    Abstract: The invention relates to a method and a device for screening first particles out of a granulate comprised of first and second particles by conveying the granulate along a first screen surface which extends outward from a vibrating device, wherein the first particles have an aspect ratio a1, with a1>3:1, and the dimensions of the second particles allow them to fall through the mesh of the first screen surface.

  • Method for Forming a Structure
    Publication number: 20080146016
    Abstract: Method for constructing a line or dotted structure on a support, especially for constructing strip-like electrically conducting contacts on a semiconductor component such as a solar cell, by applying an electrically conducting paste-like substance containing a solvent adhering to a support and subsequent hardening of the substance. After the substance is applied to the support, a medium containing a polar molecule is applied on the support and/or the substance, through which the solvent contained in the substance is extracted.

  • Process for conveying solid particles
    Publication number: 20070184560
    Abstract: A process for conveying solid particles of irregular geometry, preferably polygonal geometry, through a pipe system, where the solid particles are conveyed by a gas. In order to enable metering through fragments or other solid particles of irregular geometry in desired quantities without any risk of the particles becoming trapped in the pipe system and causing blockages, further solid particles of regular geometry are added to the solids particles of irregular geometry.

  • Method for constructing a layer structure on a substrate
    Patent number: 7253355
    Abstract: The invention relates to a method for constructing a layer structure on an especially fragile flat substrate. In order for thin, fragile flat substrates to be able to be subjected to refinement or construction of semiconductor components, a process is proposed with the steps: Applying an inorganic ceramic phase to the fragile substrate and subsequent heat treatment for hardening and sintering the inorganic ceramic material.

  • Method and device for treating and/or coating a surface of an object
    Patent number: 6875468
    Abstract: Method for treating and/or coating a surface of an object, especially for coating a surface of a substrate such as a semiconductor component or solar cell, in which the surface is supplied with a gas that contains particles that will interact and/or react with the surface, forming a coating thereon. The surface of the object is oriented at an angle ? from the vertical, and the gas is directed toward the surface such that it flows along the object by force of convection, starting from the base area of the surface of the object.

  • Method and means for producing a layered system of semiconductors
    Patent number: 5053355
    Abstract: A method and means for producing a layered semiconductor system are proposed wherein the required semiconductor layers are deposited on a carrier layer (10) through interaction with a melt (42). The carrier layer (10) itself may have a basic layer consisting of glass or quartz, which in turn may be formed from a melt by solidification on a metal melt.
