| 20080285059 | APPARATUS AND METHOD FOR IN-SITU MONITORING OF WAFER BONDING TIME - An apparatus and a method for semiconductor wafer bonding provide in-situ and real time monitoring of semiconductor wafer bonding time. Deflection of the wafer edges during the last phase of the direct bonding process indicates the end of the bonding process. The apparatus utilizes a distance sensor to measure the deflection of the wafer edges and the bonding time is measured as the time between applying the force (bonding initiation) and completion of the bonding process. The bonding time is used as a real-time quality control parameter for the wafer bonding process. | 11-20-2008 |
| 20080237315 | APPARATUS AND METHOD FOR SEMICONDUCTOR WAFER BUMPING VIA INJECTION MOLDED SOLDER - An improved apparatus for filling patterned mold cavities formed on a surface of a mold structure with solder includes an injector head assembly comprising a solder reservoir having a bottom surface with an elongated slot for injecting solder into the mold cavities and a carriage assembly configured to carry and scan the mold structure under the injector head assembly. The mold structure is brought into contact with the solder reservoir bottom surface and a seal is formed between an area of the solder reservoir bottom surface surrounding the elongated slot and the mold structure surface and then the mold structure is scanned under the injector head assembly in a first direction from a starting position to a finish position for filling the mold cavities and in a second direction opposite to the first direction for returning back from the finish position to the starting position. | 10-02-2008 |
