Patent number: 9147639Abstract: A method of processing semiconductor dies is provided. Each semiconductor die has a first side with one or more terminals, a second side opposite the first side and sidewalls extending between the first and the second sides. The semiconductor dies are processed by placing the semiconductor dies on a support substrate so that the first side of each semiconductor die faces the support substrate and the second side faces away from the support substrate. A coating is applied to the semiconductor dies placed on the support substrate. The coating has a lower reflectivity than the first side of the semiconductor dies. The coating covers the second side and at least a region of the sidewalls nearest the second side of each semiconductor die. The semiconductor dies are removed from the support substrate after applying the coating for further processing as loose dies such as taping.Type: GrantFiled: August 30, 2013Date of Patent: September 29, 2015Assignee: Infineon Technologies AGInventors: Mathias Vaupel, Günther Ruhl

Patent number: 7071110Abstract: A process enables plasma etching of materials that do not contain silicon. The process is particularly suitable for the side wall passivation of chromium layers in masks for fabricating semiconductor components. The plasma contains oxygen and/or nitrogen, and at least one silicon-donating compound is introduced into the plasma. This allows efficient passivation of side walls.Type: GrantFiled: January 31, 2003Date of Patent: July 4, 2006Assignee: Infineon Technologies AGInventors: Josef Mathuni, Günther Ruhl

Patent number: 6953644Abstract: A method for compensating for scatter/reflection effects in particle beam lithography includes the following steps: providing at least one layer of a material that is sensitive to particle beams, using at least one particle beam to write predetermined patterns in a limited area of the material that is sensitive to particle beams, and using at least one particle beam to write at least one frame, which surrounds the limited area, into the material that is sensitive to particle beams so that variations in the background dose within the limited area are less than 30% of the maximum background dose within the limited area. This provides the advantage that a considerably more homogeneous background dose and hence considerably less variation in the CD measure, can be produced within the area that is written to by the particle beam, in a simple and cost-effective manner.Type: GrantFiled: April 7, 2003Date of Patent: October 11, 2005Assignee: Infineon Technologies AGInventors: Christian Ebi, Frank Erber, Torsten Franke, Fritz Gans, Tarek Lutz, Günther Ruhl, Bernd Schönherr

Publication number: 20020137353Abstract: A method and a device are proposed for delacquering a mask substrate, in the case of which, in particular, the edge zone of a photomask is delacquered. During the mask production, the mask substrate is coated over its entire surface with a layer of photoresist by the production process. The side edges can also be coated with resist in this case. During later handling of the mask substrates, very small resist particles can come loose, for example owing to handling tools such as mask pincers, and lead through deposits on the emulsion side to defects in the layout of the mask substrates such that the photomask can then no longer be used in practice. This fault can be avoided by delacquering the edge zone with the aid of a chemical etching reaction, in particular by using an ozone-containing gas.Type: ApplicationFiled: March 26, 2002Publication date: September 26, 2002Inventors: Josef Mathuni, Gunther Ruhl
