Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the dimensions of semiconductor devices are scaled down, then computing ability is improved, but structure stability of adjacent electrodes deteriorates causing wobbling
Solution Approach 1:
A support bracing structure is introduced as an intermediary element between adjacent bottom electrodes. This bracing structure includes a first bracing layer with connection portions positioned on top surfaces of adjacent bottom electrodes and a frame portion bridging these connection portions, thereby preventing direct contact and wobbling between electrodes while enabling continued scaling for improved computing ability.
2Productivity
If adjacent bottom electrodes are positioned closely together, then device density is improved, but structural stability deteriorates leading to electrode wobbling
Solution Approach 1:
The support bracing structure serves as a mediator that enables electrodes to be positioned closely together for high device density while preventing structural instability. The bracing structure's frame portion bridges connection portions on adjacent electrodes, providing mechanical support that prevents wobbling even when electrodes are in close proximity.
Solution Approach 2:
Instead of addressing electrode stability in the horizontal plane only, the invention introduces a vertical dimension by adding the support bracing structure that extends upward from the electrode surfaces. This three-dimensional approach allows dense packing in the horizontal plane while maintaining stability through vertical bracing elements.
3Stability of the object's composition
If a support bracing structure is added to stabilize adjacent electrodes, then structure stability is improved, but device complexity increases
Solution Approach 1:
The support bracing structure is segmented into distinct functional portions: connection portions that attach to electrode top surfaces and a frame portion that bridges these connections. This segmentation allows the bracing structure to be integrated into existing electrode architectures without requiring complete redesign, thereby improving stability while limiting the increase in overall device complexity.
