What is a silicon capacitor?

It then compares thecomponents’ sizes, materials and characteristics including technical and electrical parameters in detail. Silicon capacitors are passive devices used in specific applications, such as radio frequency, medical, aerospace, automotive, circuit decoupling and electrostatic discharge protection.

Can silicon capacitors compete with MLCCs capacitors?

Thanks to the different technologies shown on this report, Silicon capacitors are able to compete with MLCCs capacitors. The list below regroup all the general data on the capacitors studied in this report. A detailed study of a relation between the capacitance and the structure of those capacitors will be detailed in the Physical Comparison part.

Who makes capacitors?

Those capacitors are designed and manufactured by the companies IPDiA, Vishay, Skyworks and TSMC. All of the capacitors are manufactured on a silicon substrate to increase the level of integration in complex electronic circuits. In this report it is present a comparison of each structures.

What are TSMC capacitors?

Si capacitors from TSMC are land-side decoupling capacitors found in A14 and M1 application processors from Apple. The other five devices are multipurpose planar capacitors from Microchip, Macom, Skyworks, and Vishay. passive integration, along with a comparison of all devices analyzed.

Who makes silicon capacitors?

This comparative report has been conducted to provide insight on technology data, manufacturing cost and selling price of different Silicon Capacitors. Those capacitors are designed and manufactured by the companies IPDiA, Vishay, Skyworks and TSMC.

Why do ipdia capacitors have a double polysilicon layer?

IPDiA use the double polysilicon layer to increase the capacitance (two capacitors in parallel) in the same area and thus increase integration of dies. For example, the second IPDiA capacitor in the table has an area four times smaller than the first one but a capacitance ten times smaller.
