Engineering Contradiction Analysis
1Reliability
If a complex structure is used for chip resistor components, then the functional requirements are met, but the manufacturing complexity and cost increase
Solution Approach 1:
The substrate is divided into multiple resistor-forming strips by forming intersecting first and second notches, creating segmented regions that can be independently processed. This segmentation allows simultaneous formation of multiple resistors in parallel, reducing overall manufacturing complexity while maintaining functional requirements
Solution Approach 2:
Multiple functional layers (electrodes, resistor films, insulator layers, shield layers) are combined and formed simultaneously on multiple substrate regions during the same processing steps. The method merges the formation of upper electrodes, lower electrodes, resistor films, and insulating layers into integrated processing sequences, reducing the total number of manufacturing steps
2Reliability
If multiple processing steps are used to form complex resistor structures, then the component functionality is achieved, but the manufacturing time and cost increase
Solution Approach 1:
The manufacturing process maintains continuous useful action by forming multiple layers and structures in parallel across different substrate regions without interrupting the processing flow. Upper electrodes, lower electrodes, resistor films, and insulator layers are formed in continuous sequences, eliminating idle time between steps and maximizing production efficiency
Solution Approach 2:
Notches are formed in advance to pre-defin e the locations of resistor-forming strips before any electrode or film deposition begins. This preliminary action establishes the geometric framework that guides subsequent material deposition, allowing all subsequent steps to proceed in parallel without repositioning or realignment, significantly reducing total manufacturing time
