Abstract

The invention discloses a film projection plan simulation method, device and system. The wafer throwing plan simulation method comprises the following steps: obtaining production information of a wafer throwing plan to be simulated; obtaining wafer production information according to the production information and the work-in-process information; and if it is monitored that the system operation time reaches any planned wafer feeding time in the wafer production information, modifying the state information of a target non-production batch corresponding to the any planned wafer feeding time in the wafer production information into the idle state, and modifying the state information of the target non-production batch from the idle state to the production state according to a received production instruction corresponding to the target non-production batch. According to the method, the chip throwing plan can be simulated, the unpredictable risk caused by direct application of the chip throwing plan to the production line can be prevented, and the overall production efficiency is continuously and stably improved.

Description

technical field [0001] The present application relates to the technical field of integrated circuit manufacturing, in particular to a method, device and system for simulation of a die plan. Background technique [0002] Semiconductor manufacturing is a high-tech industry with high investment. Semiconductor manufacturing plants are increasingly automating their production control activities in order to achieve their operational goals and increase productivity. Among them, in the semiconductor manufacturing process, the automatic control of dispatching workers is particularly important. [0003] Most advanced fabs use real-time dispatch system (Real Time Dispatch, RTD) to be responsible for dispatching workers on the production line. RTD can make reasonable assignment results for online batches (Lots) through the built-in algorithm, and the manufacturing department (MA) only needs to produce according to the Lot sequence recommended by RTD, thereby improving the overall prod...
