The MIS (metal-insulating layer-silicon) chip
capacitor are devices that have a very high Q and
small size for use in microwave hybrid circuit
applications. Large rectangular contacts are
supplied on most units with the periphery of the
contact being typically 2 mils from the edge allowing
wire or ribbon bonding near the edge for the lowest
practical inductance.

The dielectric layer is composed of a thermally
grown silicon dioxide over which a thicker layer of
silicon nitride is deposited. This layer is carried out to
the edge of the chip. The end result is a capacitor
having a thin, high breakdown dielectric resulting in
a high capacitance per unit area. This dual insulating
layer exhibits a low temperature coefficient, very
high insulation resistance and much lower insertion
loss at microwave frequencies than porcelain
capacitors. These MIS devices (sometimes referred
to as MNOS) exhibit long term stability under bias
conditions at high temperatures (as compared to the
earlier MOS technology) making them suitable for
high reliability applications.

These MIS chip capacitors provide much improved
performance over other types in hybrid microwave
circuits. They provide low loss in supply decoupling
circuits and GaAs FET transistor source bypass
(providing more gain per stage). They can also be
used as tuning elements in various filters and
matching networks. Detector diodes and transistors
can be mounted on them also to provide DC
isolation and a tuning or bypass capacitor to ground.
Switch and comb generator performance is
significantly improved using MIS capacitors. There
are no resonance problems associated with MIS
devices.
