| 20080211113 | WAFER LEVEL PACKAGING - Through vias in a substrate are formed by creating a trench in a top side of the substrate and at least one trench in the back side of the substrate. The sum of the depths of the trenches at least equals the height of the substrate. The trenches cross at intersections, which accordingly form the through vias from the top side to the back side. The through vias are filled with a conductor to form contacts on both sides and the edge of the substrate. Contacts on the backside are formed at each of the trench. The through vias from the edge contacts. Traces connect bond pads to the conductor in the through via. Some traces are parallel to the back side traces. Some traces are skew to the back side traces. The substrate is diced to form individual die. | 09-04-2008 |
| 20090014858 | PACKAGED SEMICONDUCTOR ASSEMBLIES AND METHODS FOR MANUFACTURING SUCH ASSEMBLIES - Packaged semiconductor assemblies including interconnect structures and methods for forming such interconnect structures are disclosed herein. One embodiment of a packaged semiconductor assembly includes a support member having a first bond-site and a die carried by the support member having a second bond-site. An interconnect structure is connected between the first and second bond-sites and includes a wire that is coupled to at least one of the first and second bond-sites. The interconnect structure also includes a third bond-site coupled to the wire between the first and second bond-sites. | 01-15-2009 |
| 20100072603 | SEMICONDUCTOR DEVICE ASSEMBLIES AND PACKAGES WITH EDGE CONTACTS AND SACRIFICIAL SUBSTRATES AND OTHER INTERMEDIATE STRUCTURES USED OR FORMED IN FABRICATING THE ASSEMBLIES OR PACKAGES - A sacrificial substrate for fabricating semiconductor device assemblies and packages with edge contacts includes conductive elements on a surface thereof, which are located so as to align along a street between each adjacent pair of semiconductor devices on the device substrate. A semiconductor device assembly or package includes a semiconductor device, a redistribution layer over an active surface of the semiconductor device, and dielectric material coating at least portions of an outer periphery of the semiconductor device. Peripheral sections of contacts are located on the peripheral edge and electrically isolated therefrom by the dielectric coating. The contacts may also include upper sections that extend partially over the active surface of the semiconductor device. The assembly or package may include any type of semiconductor device, including a processor, a memory device, and emitter, or an optically sensitive device. | 03-25-2010 |
| 20100146780 | METHOD FOR PACKAGING CIRCUITS AND PACKAGED CIRCUITS - A method for packaging integrated circuit chips (die) is described that includes providing a base substrate with package level contacts, coating a base substrate with adhesive, placing dies on the adhesive, electrically connecting the die to the package level contacts, and removing the backside of the base substrate to expose the backside of the package level contacts. Accordingly, an essentially true chip scale package is formed. Multi-chip modules are formed by filling gaps between the chips with an encapsulant. In an embodiment, chips are interconnected by electrical connections between package level contacts in the base substrate. In an embodiment, substrates each having chips are adhered back-to-back with through vias formed in aligned saw streets to interconnect the back-to-back chip assembly. | 06-17-2010 |
