System and priority ranking method

Abstract

The invention relates to a system and a priority ranking method. The system comprises an operation screen with a setting function and a display function, an EAP system and a controller, wherein the setting function is suitable for setting sorted priority information items; the display function is adapted to display an output of the controller. According to the invention, the order of goods discharging can be better controlled, and manual mistaken goods discharging is reduced, so that the goods delivery period and the product index are ensured.

Description

technical field [0001] The invention relates to the field of semiconductors, in particular to a system and a prioritization method. Background technique [0002] In the production and manufacture of integrated circuits, each wafer needs to go through hundreds or even thousands of processes from raw materials to final products, and all the processes that the wafer passes through constitute the process flow. Under normal circumstances, the wafer performs each process step by step on the equipment corresponding to the process according to the preset process flow, that is to say, the content of each process in the process flow is preset, and each process The content also includes specific process parameters, and the process drive engine controls the wafer to execute each process in sequence according to the preset process flow. [0003] With the development of semiconductor technology, semiconductor companies will use software control systems to maximize the production capacity...
