Publication number: 20150115451Abstract: A semiconductor device package that incorporates a combination of ceramic, organic, and metallic materials that are coupled using silver is provided. The silver is applied in the form of fine particles under pressure and a low temperature. After application, the silver forms a solid that has a typical melting point of silver, and therefore the finished package can withstand temperatures significantly higher than the manufacturing temperature. Further, since the silver is an interfacial material between the various combined materials, the effect of differing material properties between ceramic, organic, and metallic components, such as coefficient of thermal expansion, is reduced due to low temperature of bonding and the ductility of the silver.Type: ApplicationFiled: October 31, 2013Publication date: April 30, 2015Applicant: FREESCALE SEMICONDUCTOR, INC.Inventor: LAKSHMINARAYAN VISWANATHAN

Publication number: 20150115266Abstract: The embodiments described herein provide a die crack detector and method that use a conductive trace arranged to at least substantially extend around a perimeter of an integrated circuit die. A one-time programmable element, such as a fuse, is coupled in series with the conductive trace, and a package lead is electrically coupled to both the fuse and another operational element on the integrated circuit die. With the fuse intact the package lead can thus be used to determine a measurement of the conductivity of the conductive trace, with the measurement of conductivity indicative of the presence of a crack on the die. After such testing the fuse can be electrically opened, and the package lead used for normal operation of the device on the packaged die without the conductive trace interfering with this operation.Type: ApplicationFiled: October 28, 2013Publication date: April 30, 2015Applicant: Freescale Semiconductor, Inc.Inventors: Audel A.

Publication number: 20150114572Abstract: The embodiments described herein provide an apparatus and method for separating dies from adhesive tape. In general, these techniques use applied vacuum and one or more channels in an extractor base surface to progressively peel adhesive tape away from the die.
