  • Patent number: 10073444
    Abstract: Since single and dual-arm tools behave differently, it is difficult to coordinate their activities in a hybrid multi-cluster tool that is composed of both single- and dual-arm tools. Aiming at finding an optimal one-wafer cyclic schedule for a treelike hybrid multi-cluster tool whose bottleneck tool is process-bound, the present work extends a resource-oriented Petri net to model such system. By the developed Petri net model, to find a one-wafer cyclic schedule is to determine robot waiting times. By doing so, it is shown that, for any treelike hybrid multi-cluster tool whose bottleneck tool is process-bound, there is always a one-wafer cyclic schedule. Then, computationally efficient algorithms are developed to obtain the minimal cycle time and the optimal one-wafer cyclic schedule. Examples are given to illustrate the developed method.

  • Patent number: 10060886
    Abstract: Described is a method of generating a flow having a composition gradient such as a mobile phase gradient for liquid chromatography. A pair of pumps is operated such that the initiations of pump strokes for one pump are controlled to occur between the initiations of pump strokes for the other pump so that the sequences of pump strokes fort the two pumps are interspersed in time. Initiations of the pump strokes of the second pump are offset in time relative to initiations of the pump strokes of the first pump such that variations in the flow rates of the first and second pumps due to initiation do not overlap in time. The volume of liquid contributed by a pump stroke is controlled according to the relative contribution of the respective pump to the composition gradient.

  • Patent number: 10001772
    Abstract: Recent trends of larger wafer and smaller lot sizes bring cluster tools with frequent lot switches. Practitioners must deal with more transient processes during such switches, including start-up and close-down processes. To obtain higher yield, it is necessary to shorten the duration of transient processes. Much prior effort was poured into the modeling and scheduling for the steady state of cluster tools. In the existing literature, no attention has been turned to optimize the close-down process for single-arm cluster tools with wafer residency constraints. This invention intends to do so by 1) developing a Petri net model to analyze their scheduling properties and 2) proposing Petri net-based methods to solve their close-down optimal scheduling problems under different workloads among their process steps. Industrial examples are used to illustrate the effectiveness and application of the proposed methods.

  • Patent number: 10001773
    Abstract: The scheduling problem of a multi-cluster tool with a tree topology whose bottleneck tool is process-bound is investigated. A method for scheduling the multi-cluster tool to thereby generate an optimal one-wafer cyclic schedule for this multi-cluster tool is provided. A Petri net (PN) model is developed for the multi-cluster tool by explicitly modeling robot waiting times such that a schedule is determined by setting the robot waiting times. Based on the PN model, sufficient and necessary conditions under which a one-wafer cyclic schedule exists are derived and it is shown that an optimal one-wafer cyclic schedule can be always found. Then, efficient algorithms are given to find the optimal cycle time and its optimal schedule. Examples are used to demonstrate the scheduling method.
