Here’s PatSnap Eureka !
Summary
Problems
Semiconductor devices face challenges in maintaining stable power supply voltage due to voltage drops, leading to noise and instability, which existing compensation capacitance elements struggle to address effectively due to resistance issues and space constraints.
Innovation solutions

General conflict description:
Principle concept:
If multiple compensation capacitance elements are coupled in series to reduce voltage difference and prevent current leakage, then reliability is improved, but resistance at intermediate nodes increases
Why choose this principle:
The capacitance block is divided into multiple capacitance elements (first, second, third, and fourth capacitance elements) coupled in series between the first and second power supply lines. This segmentation allows the total voltage difference to be distributed across multiple elements, keeping the voltage difference across each element below the threshold that causes current leakage, thereby improving reliability.
Principle concept:
If multiple compensation capacitance elements are coupled in series to reduce voltage difference and prevent current leakage, then reliability is improved, but resistance at intermediate nodes increases
Why choose this principle:
Fifth capacitance elements are introduced as intermediary components coupled between the intermediate nodes of the series-connected capacitance elements and the second power supply line. These intermediary elements provide additional current paths that reduce the resistance at intermediate nodes, preventing the harmful effect of high resistance while maintaining the series configuration that prevents current leakage.

Abstract
Apparatuses including compensation capacitors are described. An example apparatus includes: first, second and third capacitors arranged such that the second capacitor is sandwiched between the first and third capacitors, each of the first, second and third capacitors including first and second electrodes. The first electrodes of the first, second and third capacitors are electrically coupled in common to one another. The second electrodes of the first and third capacitors are electrically coupled in common to each other. The second electrode of the second capacitor is electrically insulated from the second electrodes of the first and third capacitors.
