Why Si-Cap ?
Conventional Capacitor

A conventional capacitor is a type of capacitor that uses a dielectric material to separate two conductive plates. The dielectric material can be made of materials such as ceramic, paper, or mica, and it determines the capacitance value of the capacitor. The two conductive plates are usually made of metal, saluminum or copper, and are separated by the dielectric material. When a voltage is applied to the capacitor, electrical energy is stored in the electric field between the two plates.
Silicon capacitor and MLCC

MLCCs(multi-layer ceramic capacitors) are a type of capacitor that is widely used in electronic devices due to their high capacitance values, small size, and low cost. They consist of alternating layers of ceramic material and metal electrodes that are stacked together and then fired at high temperatures to create a solid ceramic block. MLCCs are commonly used in power supplies, filters, decoupling circuits, and other applications that require high capacitance and low ESR.
However, MLCCs have some limitations that can affect their performance and reliability. Silicon capacitors are a newer type of capacitor that has emerged as an alternative to MLCCs.

Difference between
Silicon capacitor and MLCC

Si-Cap
(Silicon capacitors)

MLCC
(Multi-layer ceramic capacitors)
-
Big & Little Core Run with Low & High Load
-
Stable Voltage & Fast Power Supply for Very Close to IC
-
Extremely Low Change in Capacitance under Operating Temperature and Voltage Ranges
-

Lower Impedance Peak

Thinner Thickness






Silicon capacitors are also thinner in size, making it available to be placed as a land-side capacitor at the bottom side of the package that simplify the number of power and ground fan-out layers while leaving space for other uses on the top side of the package.
