Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple distinct photomasks are used to fabricate different circuit connections, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The fabrication process is segmented into distinct stages, each handling specific types of circuit connections. First photomasks fabricate intra-die connections within individual dies, while second photomasks fabricate inter-die connections between dies. This segmentation allows each photomask to be optimized for its specific function, improving manufacturing precision without requiring all connection types to be fabricated simultaneously with a single complex photomask.
Solution Approach 2:
Intra-die connections are fabricated in advance using first photomasks before the dies are separated and repositioned. This preliminary action allows the intra-die circuitry to be completed and verified before the more complex inter-die connection fabrication using second photomasks, thereby improving overall manufacturing precision through staged optimization.
2Manufacturing precision
If multiple photomask fabrication steps are implemented, then manufacturing precision improves, but productivity decreases
Solution Approach 1:
The fabrication process is divided into parallel tracks: first photomasks operate on individual dies to create intra-die connections, while second photomasks operate on the repositioned dies to create inter-die connections. This segmentation allows different connection types to be fabricated simultaneously in different locations, improving productivity while maintaining the precision benefits of specialized photomasks for each connection type.
3Manufacturing precision
If intra-die and inter-die connections are fabricated separately, then manufacturing precision is improved, but loss of time increases
Solution Approach 1:
Intra-die connections are fabricated as a preliminary action using first photomasks before die separation and repositioning. This allows the intra-die circuitry to be completed in advance, so that when second photomasks fabricate inter-die connections later, both processes can be optimized independently for precision without requiring sequential completion of all connection types.
Solution Approach 2:
The fabrication process maintains continuity by overlapping operations: while first photomasks are fabricating intra-die connections on one set of dies, second photomasks can simultaneously fabricate inter-die connections on repositioned dies. This continuous utilization of fabrication equipment reduces overall cycle time while preserving the precision advantages of separate specialized photomasks.
