1Productivity

If the degree of integration of semiconductor chips is increased to reduce RC delay and meet demand for small-sized electronic devices, then data processing speed and device compactness are improved, but manufacturing complexity and reliability challenges increase

Engineering Contradiction:
Improvedata processing speedVSAvoidmanufacturing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The substrate is divided into a first region containing peripheral circuits and a second region containing memory cells, with different semiconductor layers formed in each region. This segmentation allows optimized manufacturing processes for each functional area, reducing overall manufacturing complexity while maintaining high integration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different semiconductor layers are formed at different vertical positions (depths) in the substrate - a first semiconductor layer in the first region and a second semiconductor layer in the second region. This vertical dimensionality enables high integration without proportionally increasing lateral manufacturing complexity.

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

2Adaptability or versatility

If multiple semiconductor layers are formed at different regions to increase integration, then chip functionality and processing capability are improved, but manufacturing precision requirements and reliability risks worsen

Engineering Contradiction:
Improvechip functionalityVSAvoidlayer formation precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Different semiconductor layers are formed with different properties in different regions - the first semiconductor layer in the peripheral circuit region has different characteristics than the second semiconductor layer in the memory cell region. This local quality approach allows each layer to be optimized for its specific function, improving overall chip functionality while managing manufacturing precision through region-specific processes.

Inventive Principle:
Principle #3Local quality

3Area of stationary object

If peripheral circuits and memory cells are integrated on the same substrate, then device compactness is improved, but RC delay and signal interference may increase

Engineering Contradiction:

Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The structure embeds different functional regions within the same substrate - peripheral circuits in the first region and memory cells in the second region, with semiconductor layers nested at different depths. This nesting achieves compact integration while maintaining signal integrity through spatial and vertical separation of different circuit functions.

Inventive Principle:
Principle #7Nested doll (Nesting)
