In the MOS capacitor theory, the voltage is the gate voltage, but the charge is the substrate charge because interesting things happen in the substrate. This unusual choice leads to the negative sign in Eq. (5.2.4). Equations (5.2.4) and (5.2.3) tell us
Among them, eCAP is efficient with the shortest power delivery distance between the die bumps and a decoupling capacitor, and is more reliable. So in this paper, simulation was performed by using eCAP to the embedded substrate platform. DSC (Die side capacitor). LSC (Land side capacitor). eCAP (Embedded capacitor). Fig. 1.
There is no depletion region when the MOS interface is in accumulation. Wdep in the PN junction and in the MOS capacitor is proportional to the square root of the band bending ( φs in the MOS case). Wdep saturates at Wdmax when Vg Vt, because φs saturates at 2 ≥ φB. FIGURE 5–12 Depletion-region width in the body of an MOS capacitor.
The capacitor itself forms the basis of digital logic circuits, and DRAM storage units (storing charge) or can simply supply a capacitance for an analog integrated circuit. It will also be the building block for the most common transistor produced – the MOS transistor. Metal is an equipotential region.
The surface potential characterises the nature of the charge at the oxide silicon interface. Capacitance of parallel plate capacitor with gap equal to the depletion layer width and dielectric constant for silicon. For the total capacitance C we must add these two capacitances in parallel, ie. ie. This is the maximum capacitance.

Embedding Capacitors into Interposers
Capacitors are placed on the package substrate close to the components they serve, and a connection between their terminals and those of the chip has to be made, spanning 5-30 mm (Figure 1a). This layout not only increases the necessary package substrate area, but also causes problems such as high wiring resistance and noise due to the long interconnections.
