Patent number: 9082753Abstract: An electrically conductive lead is formed using a bonding tool. After bonding the wire to a metal surface and extending a length of the wire beyond the bonding tool, the wire is clamped. Movement of the bonding tool imparts a kink to the wire at a location where the wire is fully separated from any metal element other than the bonding tool. A forming element, e.g., an edge or a blade skirt provided at an exterior surface of the bonding tool can help kink the wire. Twisting the wire while tensioning the wire using the bonding tool can cause the wire to break and define an end. The lead then extends from the metal surface to the end, and may exhibits a sign of the torsional force applied thereto.Type: GrantFiled: June 6, 2014Date of Patent: July 14, 2015Assignee: Invensas CorporationInventors: Belgacem Haba, Reynaldo Co, Rizza Lee Saga Cizek, Wael Zohni

Patent number: 9041227Abstract: A microelectronic package includes a substrate having a first surface. A microelectronic element overlies the first surface. Electrically conductive elements are exposed at the first surface of the substrate, at least some of which are electrically connected to the microelectronic element. The package includes wire bonds having bases bonded to respective ones of the conductive elements and ends remote from the substrate and remote from the bases.

Patent number: 8884403Abstract: According to the invention, die shift is reduced or substantially eliminated, by cutting the wafer in two stages. In some embodiments a first wafer cutting procedure is carried out prior to thinning the wafer to the prescribed die thickness; and in other embodiments the wafer is thinned to the prescribed die thickness prior to carrying out a first wafer cutting procedure. The first wafer cutting procedure includes cutting along a first set of streets to a depth greater than the prescribed die thickness and optionally along a second set of streets to a depth less than the die thickness. The result of the first cutting procedure is an array of strips or blocks of die, each including a plurality of connected die, that are less subject to shift than are individual singulated die. In a second wafer cutting procedure the die are singulated by cutting through along the second set of streets.Type: GrantFiled: December 30, 2010Date of Patent: November 11, 2014Assignee: Iinvensas CorporationInventors: Reynaldo Co, DeAnn Eileen Melcher, Weiping Pan, Grant Villavicencio
