Embodiment Construction
[0048] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0049] Such as figure 1 As shown, from the perspective of chip manufacturers, the manufacturing of semiconductor integrated circuits can be divided into two levels: the enterprise level and the equipment level. Among them, the equipment layer is mainly composed of various IC equipment. From the perspective of each equipment, it can be further divided into the control layer and the equipment layer.
[0050] (1) Enterprise layer
[0051] The enterprise-level application system of a semiconductor factory is generally a manufacturing execution system (MES), which is mainly used to formulate production planning, production management and production control. Advanced Process Control (APC) is also located on this layer.
[0052] (2) Control layer
[0053] The main body of the control layer is IC equipment, which may contain dozens to hundreds of IC equipment in a factor...
