Abstract: Embodiments of the present invention provide a novel method, system and computer program product for tracing die units during material transfer from, for example, one factory or lot to another (and efficiently maintaining correspondence between die data and an individual die during, e.g., a lot transfer process). One or more embodiments of the present invention are intended to improve the mechanism of die-level traceability by assigning individual die IDs to each die unit in, e.g., each lot, and associating a range of die IDs with a corresponding index string. When, for example, some dies are transferred from, e.g., a first lot to a second lot, the entire die information associated with the first lot is copied to the second lot, and a different index string is assigned to the second lot to indicate the actual dies or range of dies that have been transferred. The first lot's index string is then adjusted to indicate the dies remaining after the transfer.

The fill level of the precursor in the bubbler is determined as a difference between (1) a total volume of the bubbler and vapor-delivery system and (2) the determined total volume for the backfill gas.

Abstract: A chamber dry cleaning process particularly useful after a dielectric plasma etch process which exposes an underlying copper metallization. After the dielectric etch process, the production wafer is removed from the chamber and a cleaning gas is excited into a plasma to clean the chamber walls and recover the dielectric etching characteristic of the chamber.

If the wafer pedestal is vacant during the cleaning, it is not electrically biased. If a dummy wafer is placed on the pedestal during cleaning, the pedestal is biased. The cleaning process is advantageously performed every wafer cycle.

Abstract: Semiconductor wafers are processed in conjunction with a manufacturing execution system using a run-to-run controller and a fault detection system. A recipe is received from the manufacturing execution system by the run-to-run controller for controlling a tool. The recipe includes a setpoint for obtaining one or more target wafer properties. Processing of the wafers is monitored by measuring processing attributes including fault conditions and wafer properties using the fault detection system and one or more sensors. Setpoints of the recipe may be modified at the run-to-run controller according to the processing attributes to maintain the target wafer properties, except in cases when a fault condition is detected by the fault detection system. Thus, data acquired in the presence of tool or wafer fault conditions are not used for feedback purposes. In addition, fault detection models may be used to define a range of conditions indicative of a fault condition.
