Common materials used for encapsulation include epoxy resin, polyimide resin, and silicone rubber. Depending on the application, different encapsulation materials will be used to ensure a reliable and long-lasting performance of the capacitor.
How does the MIM capacitor work?
The MIM capacitor works by creating an electric field across two metal plates. This electric field is generated when a voltage is applied to the plates. The voltage causes electrons to move and accumulate on one plate while leaving the other plate with a negative charge due to electron deficiency. This creates an imbalance of charge that produces an electric field between the two plates, allowing for the storage of electric charge.

What is the Difference between MOM, MIM and MOS Capacitors?
MOM (Metal Oxide Metal) capacitors are made up of two metallic plates with an oxide dielectric between them and have the most stable electrical characteristics among all capacitors. MIM (Metal Insulator Metal) capacitors involve three layers; a metal plate, an insulation layer, and another metal plate on top. This type of capacitor has higher capacitance and lower leakage than MOM capacitors. Lastly, MOS (Metal Oxide Semiconductor) capacitors are ultra-miniature components that offer a very low profile compared to other types of capacitors, but with higher losses at high frequencies.
An important thing to consider when choosing between these three types of capacitors is their respective temperature coefficients, which can significantly affect the performance of the circuit if not taken into account. MOM capacitors have relatively low temperature coefficients while MIM and MOS capacitors have higher temperature coefficients and should be used in applications that may encounter extreme temperatures or high-frequency switching. In addition, MIM capacitors offer a higher tolerance than MOM and MOS types due to their three-layer structure. Finally, MOS capacitors are the most compact of the three types so they are often used in space-constrained applications.
Regardless of the type of capacitor chosen, it is important to understand how each type behaves under different conditions and choose the one that will best serve your needs. By considering all factors such as temperature coefficient, capacitance, size and tolerance, you can ensure that your circuit will operate as intended. Additionally, if special features such as high-frequency switching or noise suppression are required, then selecting the right type of capacitor is even more critical.
As technology continues to evolve and new types of capacitors come onto the market, it’s important to stay up-to-date on the different types and their performance characteristics to ensure that you select the right capacitor for your application needs. With the wide variety of capacitors available, it’s essential to understand how each type behaves under different environmental conditions so that you can make an informed decision when choosing a capacitor for your circuit.
