MIM Capacitor
 |
This example is an MIM capacitor which is composed of two parallel plates with a dielectric layer between the plates. A microstrip line is connected to each plate. The dielectric layer is used to represent the thin (0.2 micron) silicon nitride between the capacitor plates. This circuit contains a dielectric layer which encompasses the entire circuit. This introduces some error if the real circuit does not have silicon nitride over the entire circuit. However, for thin layers, this error may be undetectable. With Sonnet Professional, you can use dielectric bricks which allows you to limit the silicon nitride to be just between the capacitor plates.
