Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In semiconductor integrated circuit manufacturing, existing methods for product dispatching in queue time section loops fail to consider the risk level of site abnormalities, leading to inconsistent and non-intelligent dispatching results, which can affect product quality.
Innovation Solution
An automatic product dispatching device and method that utilize a risk level definition module and risk control logic module to divide the queue time section loop into current, middle, and abnormal sections, defining corresponding risk levels and forming dispatching results based on logic relationships among these levels, allowing for intelligent dispatching according to risk levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If existing methods are used for product dispatching in queue time section loops, then the dispatching process is simple, but the dispatching results are inconsistent and non-intelligent, affecting product quality
Solution Approach 1:
The patent segments the queue time section loop into multiple queue time sections, with each section having its own risk level. This segmentation allows the system to evaluate and control risk at a granular level rather than treating the entire loop uniformly, enabling intelligent dispatching decisions based on specific section conditions while maintaining manageable system complexity
Solution Approach 2:
The patent introduces risk level as a new parameter to characterize the state of each queue time section. By defining risk levels based on site abnormality conditions and queue time constraints, the system transforms complex dispatching decisions into manageable parameter comparisons and logic evaluations, achieving intelligent automation without excessive complexity
2Reliability
If risk level control is implemented in queue time section loops, then product quality risk decreases, but the system complexity increases due to multiple risk levels and logic relationships
Solution Approach 1:
The patent divides the queue time section loop into multiple queue time sections, each with its own risk level evaluation. This segmentation allows risk control to be applied locally to each section based on its specific conditions, improving product quality through targeted risk management while keeping the overall system complexity manageable through modular evaluation
Solution Approach 2:
The patent applies different risk control strategies to different queue time sections based on their local conditions. Each section's risk level is determined by its specific site abnormality status and queue time constraints, allowing the system to optimize product quality for each local context rather than applying a uniform complex control mechanism throughout
3Ease of operation
If uniform dispatching is applied to all queue time sections, then the system is easy to operate, but it cannot reflect the risk level differences, leading to suboptimal dispatching results
Solution Approach 1:
The patent uses risk level as a key parameter to differentiate dispatching decisions across queue time sections. By comparing risk levels and applying predefined logic relationships, the system achieves adaptive dispatching that responds to different risk conditions while maintaining operational simplicity through rule-based decision-making rather than complex manual judgment
