The assembly can include a first component including a dielectric region having an exposed surface, a conductive pad at the surface defined by a conductive element having at least a portion extending in an oscillating or spiral path along the surface, and a an electrically conductive bonding material joined to the conductive pad and bridging an exposed portion of the dielectric surface between adjacent segments. The conductive pad can permit electrical interconnection of the first component with a second component having a terminal joined to the pad through the electrically conductive bonding material. The path of the conductive element may or may not overlap or cross itself.Type: ApplicationFiled: December 9, 2010Publication date: May 17, 2012Applicant: Tessera Research LLCInventor: Belgacem Haba

Patent number: 8178371Abstract: A method for assembling an optically pumped solid-state laser having an extended cavity. The method includes the steps of providing a casing, mounting a TEC and a base plate in the casing, and mounting a plurality of laser components on the base plate using a UV and heat curing adhesive. Once the laser components are correctly positioned and aligned on the base plate, the adhesive is pre-cured using UV radiation. Final curing of the adhesive is obtained by subjecting the entire laser package to an ambient temperature of at least 100° C. The base plate is preferably selected to have a CTE similar to that of the laser components in order to facilitate the high temperature curing. A preferred material for the base plate is AlSiC.Type: GrantFiled: June 20, 2011Date of Patent: May 15, 2012Assignee: Cobolt ABInventors: Jonas Hellström, Gunnar Elgcrona, Kenneth Joelsson

Patent number: 8163598Abstract: In one or more embodiments, a method comprising applying thermo compression to a package assembly including a lid, a die, and a package substrate to assemble the package assembly is disclosed. The method may include assembling the package assembly without coupling a biasing mechanism to the lid. Heat may be applied to a bond head coupled with a pick and place tool. Heat may be applied to a bond stage coupled to a carrier for holding the package assembly during processing. An adhesive applied to the lid or package substrate may be allowed to at least partially cure. The method may further include, in an oven, reflowing a thermal interface material (TIM) coupled to the lid and the die, curing the TIM, and/or curing the adhesive, without using clips.Type: GrantFiled: January 14, 2011Date of Patent: April 24, 2012Assignee: Intel CorporationInventors: George Kostiew, Raj Bahadur, James Mellody, George Vakanas, Leonel Arana
