Abstract:
PROBLEM TO BE SOLVED: To provide a substrate joint technology in order to obtain electric, physical connection between external circuits in a multilayer substrate. SOLUTION: A substrate 104 has a conductive viahole 126 prepared between isolated conductive layers. A viahole 124 is formed by laser in such a manner that it penetrates an insulator separating the conductive layers. Interconnection portion to exterior which consists of a T typeface pin is soldered to the substrate 104 of an integrated circuit package. An integrated circuit 102 can be adhered to the substrate by flip chip method. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
An interconnect structure for microelectronic devices includes a first plated through hole (PTH) via formed through a core material, and a second PTH via concentrically located inside first PTH via, but electrically isolated from the first PTH via. A method of producing the interconnect structure includes forming a first hole through a core material layer, then forming a first conductive layer on sidewalls of the first hole, and on upper and lower surfaces of the core material layer. The first hole is substantially filled with non-conductive material, and dielectric layers are formed on substantially horizontal portions of the first conductive layer, and on top and bottom surfaces of the non-conductive material. A second hole, having a smaller diameter than the diameter of the first hole, is formed through the dielectric layers and the non-conductive material in concentric relationship to the first hole. A second conductive layer is then formed on the sidewalls of the second hole, and on upper and lower surfaces of the dielectric layers.
Abstract:
An integrated circuit package is provided that includes a multi-layer organic substrate. The substrate has conductive vias provided between isolated conductive layers. The vias are formed using a laser to cut through a dielectric layer separating the conductive layers. External interconnects in the form of T-shaped pins are soldered to the substrate of the integrated circuit package. An integrated circuit can be attached to the substrate using a flip-chip technique.

Abstract:
A method and apparatus for making a package having improved heat conduction characteristics and high frequency response. A relatively thick package substrate, such as copper, has a wiring layer bonded to one face, leaving the opposite face exposed, for example, to be a surface for connection to a heat sink. One ore more chips are bonded to the wiring layer, and an array of connectors, such as solder balls are provided around the periphery of the chip(s) for connection to a printed circuit board. In some embodiments, the printed circuit board has a hole that the chip(s) extend into to allow smaller external-connection solder balls. In some embodiments, a second heat sink is connected to the back of the chip through the PCB hole.
