Abstract:
A dicing tape attaching unit that can attach both a pre-cut dicing tape and a general dicing tape to a wafer in a semiconductor package assembling process, and an in-line system used in a semiconductor package process including the dicing tape attaching unit are provided. The dicing tape attaching unit supplies one of the pre-cut dicing tape and the general dicing tape and attaches it to a wafer according to the direction of rotation of a tape loader. Accordingly, without an additional pre-cut dicing tape attaching unit, either of the pre-cut dicing tape and the general dicing tape can be attached to the back side of the wafer by one and the same unit.

The at least one manufacturing tool includes at least one of an implanter tool and an annealing tool.
Abstract:
A method and apparatus for transferring a substrate between a first environment having a first pressure and a second environment having a vacuum pressure is provided. In one embodiment, the apparatus comprises a chamber body having a first port disposed in a first wall and a second port disposed in a second wall that seals the chamber from the first and second environments. A cooling plate, a first substrate holder and a second substrate holder are disposed within the chamber body. The cooling plate is disposed at the bottom of the chamber body. The first port and the second port are sequentially opened and the pressure within the load lock regulated to allow substrate to pass through the load lock. A window is disposed in the top of the chamber body that allows a metrology device to view the chamber volume.
Abstract:
A method is disclosed to determine and assess chamber inconsistency in a multi-chambered tool, especially a multi-chambered tool involved in mass production processes. Wafers produced by the tool are grouped in lots measured to obtain loss yield groups. The invention sorts yield losses to obtain a corresponding monotonic sequence. The invention then averages the monotonic sequences. If the resulting mean monotonic sequence fits with a predetermined aberration, the tool is determined to suffer from chamber inconsistency.
Abstract:
A conveyor system for parts coupled to a loadbar assembly is disclosed. The conveyor system includes a walking beam conveyor and a push bar conveyor. The loadbar assembly and walking beam conveyor are configured to allow transfer of parts coupled to loadbar assemblies along a path through upward and downward and forward and reverse movements of the walking beam conveyor. The push bar conveyor and the loadbar assembly are configured to urge parts coupled to the loadbar assemblies through the push bar conveyor by an incremental distance substantially equal to the length of a segment bar of the loadbar assembly.
