Publication number: 20150249021Abstract: A method for a packaged leadless semiconductor device including a heat sink flange to which semiconductor dies are coupled using a high temperature die attach process. The semiconductor device further includes a frame structure pre-formed with bent terminal pads. The frame structure is combined with the flange so that a lower surface of the flange and a lower section of each terminal pad are in coplanar alignment, and so that an upper section of each terminal pad overlies the flange. Interconnects interconnect the die with the upper section of the terminal pad. An encapsulant encases the frame structure, flange, die, and interconnects with the lower section of each terminal pad and the lower surface of the flange remaining exposed from the encapsulant.Type: ApplicationFiled: March 11, 2014Publication date: September 3, 2015Applicant: FREESCALE SEMICONDUCTOR, INC.Inventors: Audel A.

Patent number: 8890339Abstract: A bond pad region is provided that reduces parasitic capacitance generated between bond pad metallization and underlying silicon by reducing the effective area of the bond pad, while maintaining flexibility of wire bond sites and ensuring mechanical integrity of the wire bonds. Embodiments provide, in a region that would be populated by a traditional bus bar bond pad, a small bus bar bond pad that is less than half the area of the region and populating at least a portion of the remaining area with metal tiles that are not electrically connected to the small bus bar bond pad or to each other. The metal tiles provide an attachment area for at least a portion of one or more wire bonds. Only those tiles involved in connection to a wire bond contribute to parasitic capacitance, along with the small bus bar pad.Type: GrantFiled: April 30, 2013Date of Patent: November 18, 2014Assignee: Freescale Semiconductor, Inc.Inventors: Fernando A. Santos, Margaret A. Szymanowski, Mohd Salimin Sahludin
