基于JIT精益生产的半导体设备调度系统设计OA
Design of semiconductor equipment scheduling system based on JIT lean production
半导体设备是芯片制造的核心单元,承担光刻、刻蚀、薄膜沉积等关键工艺,其调度效率直接影响晶圆产能与工厂效益,设计出一个高效稳定的调度系统是保证最优产能的前提.然而,一方面,高精度、多环节的晶圆加工步骤使设备调度系统设计难度提升;另一方面,设备内对晶圆的调度效率会影响产能,导致对系统计算效率的要求较高.传统的调度设计方法往往基于遗传算法在解空间上搜索最优解,难以满足系统的实时性需求.文中设计通过对双集束型晶圆加工半导体设备中的出片限制、模块使用限制、禁止超片、阀门互斥限制、Just in Time共5个调度限制进行系统性分析,创新性地将加工仓任务池、机械臂任务池的任务调度问题抽象为混合整数规划(MIP)模型,并且基于数学规划求解器Gurobi进行快速求解,相较于传统算法求解速度提升了一个数量级.
Semiconductor equipment is a critical component in chip manufacturing,performing essential processes such as lithography,etching,and thin-film deposition.The efficiency of its scheduling directly impacts wafer production capacity and factory profitability.Therefore,designing an efficient and stable scheduling system is crucial for achieving optimal production output.On one hand,the high-precision,multi-step wafer processing procedures increase the complexity of designing equipment scheduling systems.On the other hand,the efficiency of wafer scheduling within the equipment directly affects production capacity,imposing stringent requirements on the system's computational efficiency.Traditional scheduling design methods,often based on genetic algorithms that search for optimal solutions within the solution space,struggle to meet real-time system demands.This study systematically analyzes five scheduling con-straints in dual-cluster wafer processing semiconductor equipment:wafer discharge constraints,module usage constraints,prohibition of overloading,valve mutual exclusion constraints,and Just in Time requirements.Innovatively,the task scheduling problem for the pro-cessing chamber task pool and the robotic arm task pool is formulated as a Mixed Integer Programming(MIP)model.By leveraging the mathematical programming solver Gurobi for rapid solution,this approach achieves a computational speed improvement of an order of magnitude compared to traditional algorithms.
