Patent number: 6576848Abstract: A wiring structure with crossover capability is disclosed. The wiring utilizes a connection stud in a contact layer, beneath the plane of the otherwise-intersecting lines as a crossover. Thus, a first wire in a first metallization layer passes below a second wire in a second metallization layer by overlapping contact with the connection stud in the contact layer. In manufacturing the wiring structure of the present invention, no intervening insulative or via layers are used between the contact layer, the first metallization layer and the second metallization layer. However, care must be taken in device layout on the substrate to ensure that the connection stud is located above isolation areas rather than active device areas.Type: GrantFiled: November 22, 1996Date of Patent: June 10, 2003Assignee: International Business Machines CorporationInventors: John Edward Cronin, John Andrew Hiltebeitel, Carter Welling Kaanta, James Gardner Ryan

Patent number: 6559527Abstract: A method of forming non-spherically shaped solder interconnects, preferably conical, for attachment of electronic components in an electronic module. Preferably, the solder interconnects of the present invention are cone shaped and comprise of depositing a first solder followed by a second solder having a lower reflow temperature than the first solder. Warm placement of the electronic component at a somewhat elevated temperature than room temperature but less than the solder reflow temperature reduces the force required during placement of a semiconductor chip to a substrate. After warm placement, reflow of the module occurs at the lower reflow temperature of the second solder. The conical shape of the solder interconnects are formed by a heated coining die which may also coin a portion of the interconnects with flat surfaces for stand-offs.Type: GrantFiled: January 3, 2001Date of Patent: May 6, 2003Assignee: International Business Machines CorporationInventors: Peter Jeffrey Brofman, Shaji Farooq, John U.
