Abstract:
A method of forming a semiconductor package (250)comprises forming one or more first vias (104) in a first side (112) of a substrate (102) and attaching a first side (124) of a first microelectronic element (122) to the first side of the substrate (102). The first microelectronic element (122) is electrically coupled to at least one of the one or more first vias (104). The method further comprise obtaining a second microelectronic element (202) including one or more second vias (207) in a first side (204) of the second microelectronic element (202), and attaching a second side (114) of the substrate (102) to the first side (204) of the second microelectronic element (202). The second microelectronic element (202) is electrically coupled to at least one of the one or more first vias (104). Each of one or more connecting elements (208) has a first end (208a) attached to a first side (204) of the second microelectronic element (202) and a second end (208b) extends beyond a second side of the first microelectronic element (122).
Abstract:
An improved apparatus for debonding temporary bonded wafers includes a debonder, a cleaning module and a taping module. A vacuum chuck is used in the debonder for holding the debonded thinned wafer and remains with the thinned debonded wafer during the follow up processes steps of cleaning and mounting onto a dicing tape. In one embodiment the debonded thinned wafer remains onto the vacuum chuck and is moved with the vacuum chuck into the cleaning module and then the taping module. In another embodiment the debonded thinned wafer remains onto the vacuum chuck and first the cleaning module moves over the thinned wafer to clean the wafer and then the taping module moves over the thinned wafer to mount a dicing tape onto the wafer.
Abstract:
A semiconductor manufacturing process for wafer-to-wafer stacking of a reconstituted wafer with a second wafer creates a stacked (3D) IC. The reconstituted wafer includes dies, die interconnects and mold compound. When stacked, the die interconnects of the reconstituted wafer correspond to die interconnects on the second wafer. Wafer-to-wafer stacking improves throughput of the manufacturing process. The reconstituted wafer may include dies of different sizes than those in the second wafer. Also, the dies of the reconstituted wafer may be singulated from a wafer having a different size than the second wafer. Thus, this wafer-to-wafer manufacturing process may combine dies and/or wafers of dissimilar sizes.
Abstract:
Methods for forming electronic assemblies are provided. A device substrate (50) having a plurality of electronic components (42) embedded therein is provided. The device substrate (50) is attached to a carrier substrate (54) using an adhesive material (56). A plurality of cuts (68) are formed through the device substrate (50) to divide the device substrate into a plurality of portions (70). Each of the plurality of portions (70) includes at least one of the electronic components (42). A force is applied to each of the plurality of portions in a direction away from the carrier substrate (54) to remove the plurality of portions (70) from the carrier substrate (54).
Abstract:
An apparatus and method for separating at least one semiconductor package (504) formed on a substrate and a tape (302) removably adhered to the semiconductor package (504) are disclosed. The apparatus comprises a transferring unit (702) for engaging and displacing the semiconductor package (504) and a station (700) for disposing the semiconductor package (504) and the tape (302) thereon and for securing the tape (302). The semiconductor package (504) and the tape (302) are separable by initially the station (700) securing the tape (302) and providing thermal energy to the tape (302) for reducing the adhesion whereby the tape (302) is removably adhered to the semiconductor package (504) and subsequently the station (700) securing the tape (302) and the transferring unit (702) securing and displacing the semiconductor package (504) from the tape (302).
