Patent number: 9561524Abstract: The invention relates to a method for processing a structured surface of an embossing tool, in which the entire surface is provided with a first metallic coating and said surface having, in selected regions, at least one additional metallic coating that has a differing degree of lustre. To improve the optical properties of the material boards produced using the embossing tools, particularly if reproducing a wood texture, the invention suggests that additional differing degrees of lustre should be produced in multiple selected regions on the first coating, and be produced by a combination of metallic coatings and mechanical or chemical after-treatments. Therefore, for example, a wood pore with a defined structure can be substantially better reproduced, and the optical and haptic properties of the wood composite board produced using the press plates can thus be improved.Type: GrantFiled: August 14, 2015Date of Patent: February 7, 2017Assignee: Hueck Rheinische GmbHInventors: Martin Marxen, Wolfgang Stoffel

Patent number: 9559063Abstract: A semiconductor device includes an interlayer insulating layer disposed over a semiconductor substrate, and including a plurality of wiring layers; a seal ring disposed in the interlayer insulating layer, and surrounding a circuit region of the semiconductor substrate; a crack lead ring disposed in the interlayer insulating layer, and surrounding the seal ring; and a protective film disposed over the interlayer insulating layer, and covering the crack lead ring and the seal ring. The crack lead ring includes an uppermost wiring layer in an uppermost layer of a plurality of wiring layers. When the crack lead ring has a wiring in an underlayer below the uppermost layer, the uppermost layer wiring extends towards the outside of the device, relative to the wiring in the underlayer. The protective film has an end overlapped with an end of the uppermost layer wiring to form a step over the interlayer insulating layer.Type: GrantFiled: July 19, 2013Date of Patent: January 31, 2017Assignee: Renesas Electronics CorporationInventors: Takeshi Watanabe, Junya Ishii, Hirofumi Saitou, Hiroyasu Kitajima, Tatsuki Kojima, Yoshitsugu Kawashima
