Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If semiconductor electronic products are scaled down to meet application demands, then device size is reduced, but electrical characteristics and quality deteriorate
Solution Approach 1:
The patent divides the semiconductor system into multiple separate chips (logic chip, memory chips) that are individually manufactured and then integrated through a package structure. This segmentation allows each chip to be optimized for its specific function while maintaining reliable electrical characteristics, avoiding the degradation that would occur if all functions were scaled down in a single chip.
Solution Approach 2:
The patent transitions from horizontal integration (single chip) to vertical integration (stacked package structure with multiple chips). By stacking chips vertically and using through-silicon vias (TSVs) for interconnection, the system achieves high integration without scaling down individual chip dimensions, thereby maintaining electrical characteristics while reducing overall device footprint.
2Adaptability or versatility
If multiple semiconductor chips are integrated to meet multifunctional needs, then functionality is enhanced, but device complexity increases
Solution Approach 1:
The package structure serves as a universal platform that can accommodate different types of semiconductor chips (logic, volatile memory, non-volatile memory) in standardized configurations. The common package design with standardized interconnection methods enables multifunctional capabilities while managing complexity through reuse of the same structural elements across different applications.
Solution Approach 2:
The package structure acts as an intermediary that simplifies the integration of multiple chips. Instead of directly connecting chips to each other in complex configurations, the package provides a standardized interface and routing layer that mediates connections, thereby reducing the overall system complexity while enabling multifunctional integration.
3Productivity
If integration level is enhanced to meet data processing needs, then data processing capability is improved, but manufacturing difficulty increases
Solution Approach 1:
The patent employs preliminary actions in the manufacturing process by pre-forming through-silicon vias (TSVs) and interconnection structures on the chips before final packaging. The encapsulant is also pre-prepared with embedded conductive structures. These preliminary actions simplify the final assembly process and enable high integration while maintaining ease of manufacture through standardized pre-processing steps.
