晶圆制造中如何理解WIP? 在硅基集成电路(IC)工艺领域,WIP(Wafer In Process)是一个非常关键的概念。 1. WIP的定义 WIP(Wafer In Process)指的是在制造工艺流程中,处于各个工艺步骤之间的晶圆数量。这些晶圆已经通过了部分制造步骤,但尚未完成整个制造流程。因此,它们在工厂的不同阶段和工艺流程之间流动。 2. WIP...
有的人说WIP应该指的是Wafer In Process,小编觉得比较片面。芯片制造过程主要分为前后段两个工厂的合力完成,前段是晶圆加工厂,原料和成品都是一片一片的晶圆(Wafer)形态,用Wafer In Process代表WIP可以理解。后段是封装测试厂,原料是已经加工的晶圆,成品变成了一颗一颗的Chip,用Wafer 就解释不通啦,用Work In Proc...
在芯片制造过程中，前段工厂主要负责晶圆的加工，此时原料和成品均呈现为一片片的晶圆形态，因此用Wafer In Process来代表WIP是合适的。然而，后段工厂则进行封装测试，其原料已是加工完成的晶圆，而成品则变为一颗颗的Chip。在这种情况下，若仍使用Wafer来描述，就显得不太恰当。相比之下，Work In Process这一术语...
1、WIP: Wafer in Process, 指已经下线但还没出货的wafer片数; 2、Monitor Wafer: 控片,用来做daily、routine monitor的,看机台有没有异常,或者参数shift。 3、Dummy wafer:假片,用来做season(暖机),或者用来填充/补足空缺(炉管)。 4、PM: Prevention&Maintenance,预防和保养。FAB的原材料和产品都非常昂贵,...

semiconductor wafer fabrication system (SWFS)The performance of a wafer fabrication system is constrained by its bottlenecks, which are difficult to detect and improve due to the complexity within the system. To weaken the negative effects of bottlenecks, a work in process (WIP) strategy is ...
WIP(Wafer In Process)指的是在制造工艺流程中,处于各个工艺步骤之间的晶圆数量。这些晶圆已经通过了部分制造步骤,但尚未完成整个制造流程。因此,它们在工厂的不同阶段和工艺流程之间流动。 2. WIP的重要性 WIP是衡量工厂生产效率和资源管理的重要指标之一。WIP的数量直接影响工厂的产能、生产周期(Cycle Time)和运营成...
