Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple adhesive members are used to adhere multiple semiconductor chips to each other, then the integration of multiple chips is achieved, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improveintegration of multiple chipsVSAvoidnumber of adhesive members
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple adhesive members into a single adhesive layer that simultaneously bonds multiple semiconductor chips to the substrate. This single adhesive layer performs the function of multiple separate adhesive members, reducing structural complexity while maintaining the integration of multiple chips. The adhesive layer is applied as a continuous or discontinuous coating that adheres multiple chips in a stacked or side-by-side configuration without requiring individual adhesive members for each chip.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple adhesive members are used to adhere multiple semiconductor chips to each other, then the integration of multiple chips is achieved, but the productivity decreases

Engineering Contradiction:
Improveintegration of multiple chipsVSAvoidmanufacturing efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies adhesive members or adhesive layer in advance before mounting the semiconductor chips onto the substrate. This preliminary application of adhesive allows for more efficient assembly processes, as the adhesive is already in place to receive the chips during subsequent mounting operations. This approach eliminates the need for complex multi-step adhesive application processes during chip assembly, thereby improving manufacturing productivity.

Inventive Principle:
Principle #10Preliminary action

3Weight of moving object

If the size of individual semiconductor components is reduced to create small and light electronic components, then the portability is improved, but the integration density and electrical connection reliability become more difficult to maintain

Engineering Contradiction:
Improveweight of electronic componentsVSAvoidelectrical connection reliability
Core Design Contradiction:
Weight of moving objectVSReliability

Solution Approach 1:

The patent transitions from planar arrangement of semiconductor chips to a three-dimensional stacked configuration. Multiple chips are arranged vertically in layers rather than spread out horizontally, enabling compact integration while maintaining reliable electrical connections through vertical interconnect structures. This dimensional change allows small, lightweight components to achieve high integration density without compromising connection reliability, as the stacked architecture reduces the overall package size and weight while maintaining robust electrical pathways between chips and substrate.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
