What is MIM structure?

A capacitor is an electronic device with a dielectric layer separated by two electrodes, known as a metal-insulator-metal (MIM) structure. The electrodes could be two parallel metallic plates or wires. Charges tend to accumulate at the interface between the insulator and electrodes.

What is the structure of a capacitor?

The basic structure of capacitor consists of two parallel metal foils (very thin sheets of metal). The metal foils act as electrode. Dielectric material is use as as insulator to separate metal foils. The term “di” in dielectric refers to placement in between two (di) foils and electric means it holds electric field.

What is a mom capacitor?

MOM (metal-oxide-metal, or VPP – vertical parallel-plate, or VNC – vertical natural capacitor) is an inter-digitated multi-finger capacitor formed by multiple metal layers (optionally connected by vias) in the vertical BEOL (back-end-of-line) stack separated by inter-metal dielectrics.

What is the basic construction of a capacitor?

A capacitor consists of two metal plates separated by a dielectric. The dielectric can be made of many insulating materials such as air, glass, paper, plastic etc. A capacitor is capable of storing electrical charge and energy.

What is MIM cap in VLSI?

What is MIMCAP? Metal-Insulator-Metal (MIM) capacitors are parallel plate capacitors formed by two metal films. There is a thin insulating dielectric layer between Capacitor top metal- CTM and capacitor bottom metal- CBM layers. While dielectric layers are made from silicon nitride or silicon oxide.

What is the difference between MIM and MOM capacitor?

MIM is metal-insulator-metal = Usually a parallel plate capacitor. MOM is metal-oxide-metal = (Yes I know oxide is also an insulator) But this usually refers to an interdigitated capacitor. It uses lateral (fringe) fields.

What is MIM VLSI?

Metal-Insulator-Metal (MIM) capacitors are parallel plate capacitors formed by two metal films. There is a thin insulating dielectric layer between Capacitor top metal- CTM and capacitor bottom metal- CBM layers. While dielectric layers are made from silicon nitride or silicon oxide.

What is capacitor explain with diagram?

A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals. Most capacitors contain at least two electrical conductors often in the form of metallic plates or surfaces separated by a dielectric medium.

What is metal oxide metal capacitor?

At the heart of all charge-coupled devices (CCDs) is a light-sensitive metal oxide semiconductor (MOS) capacitor, which has three components consisting of a metal electrode (or gate), an insulating film of silicon dioxide, and a silicon substrate.

What are the different classifications of capacitor according to use?

Capacitors are divided into two mechanical groups: Fixed capacitors with fixed capacitance values and variable capacitors with variable (trimmer) or adjustable (tunable) capacitance values. The most important group is the fixed capacitors.
