Patent number: 9661770Abstract: Techniques for graphic formation via material ablation described. In at least some implementations, a graphic is applied to a surface of an object by ablating layers of the object to form an ablation trench in the shape of the graphic. In at least some embodiments, an object can include a surface layer and multiple sublayers of materials. When an ablation trench is generated in the object, the ablation trench can penetrate a surface layer of the object and into an intermediate layer. In at least some implementations, height variations in an object surface caused by an ablation trench can cause variations in light reflection properties such that a graphic applied via the ablation trench appears at a different color tone than a surrounding surface, even if the ablation trench and the surrounding surface are coated with a same colored coating.Type: GrantFiled: March 4, 2013Date of Patent: May 23, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Mark Thomas McCormack, Raj N. Master, Michael Joseph Lane, Krishna Darbha, Ralf Groene, James Alec Ishihara, Joshua James Fischer

Patent number: 7601612Abstract: A method for forming a solder joint for a package arrangement with a dispersed Sn microstructure provides a flip chip on a package, with a flip chip having solder bumps to be connected by eutectic solder joints to pads on the package. The eutectic solder is reflowed at a solder bump/pad interface with a eutectic reflow profile that is configured to achieve eutectic solder joints having substantially evenly distributed Sn grains. The eutectic reflow profile includes an increased cooling rate and decreased hold time with a higher peak temperature. A defined ratio of the pad openings in the solder mask to the under bump metallurgy is provided. The eutectic reflow profile and the defined ratio prolong fatigue life in the package arrangement.Type: GrantFiled: October 24, 2005Date of Patent: October 13, 2009Assignee: GlobalFoundries Inc.Inventors: Raj N.
