Silicon Chip Capacitors MIS MOS MNOS CXXXX - Series of chip capacitors are designed to be used as RF bypass, DC blocks coupling filter
elements and microwave circuit resonant elements. When used as resonant elements in oscillators, Q has to be as high as possible while
the temperature coefficient has to be as small as possible. U. S. MICROWAVES advanced semiconductor and thin film technologies allow
for an important reduction of the series resistance DCR that is increasing the SRF of the capacitor. High quality dielectrics with low loss
factors translate into an increased Q. The microwave capacitors are manufactured on high conductivity silicon substrates. The dielectrics
are SiO2 and Si3N4 and the capacitors are available with single or dual dielectric. The die thickness is 0.005 +/- 0.001. The top plate of
the capacitors is 99.99% electroplated or sputtered gold with a TiW barrier that withstands half hour at 400 deg. C without loss of
adhesion. Minimum 1.5 micrometers of Au enhance the top plate bond ability. The backside of the die is metalized with Ti/Pt/Au, which
is compatible with most die attaching methods. The MNOS type of capacitors has low voltage coefficients, low TCC, high Q and high
dielectric breakdown. Capacitors are 100% visually inspected and packaged in waffle packs, gel packs or vials.

SEMICONIX Designs and manufactures standard and custom
bipolar and MOS analog devices, semiconductors, analog integrated circuits, discrete components for high performance systems such
as cellular/wireless, video amplifiers, heart pacemakers and medical imaging systems. Standard semiconductor components are designed
and manufactured for space, medical, telecommunications and military applications only. Company's technology road map is including
SiGe epi devices for high speed RF bipolars and high speed fiber optic and optoelectronic applications. Analog devices, ASIC analog
design and manufacturing: Semiconix produces a series of semi-custom bipolar analog devices in arrays that are customized by designing
a specific metal interconnection mask. The arrays contain a large number of undedicated active and passive components, i.e. transistors,
diodes, resistors, capacitors, MOSFET s, LDMOS, photodiodes, phototransistors, etc. Since wafers are stocked before the metal mask,
the custom IC development phase is shorter and far less expensive compared to conventional full custom ICs. Customers may provide
own analog design. Optoelectronic components: photodiodes, photodiodes arrays, phototransistors, position sensing devices, optocouplers,
optoisolators, photodarlington, high voltage phototransistors output, Schottky infrared detectors. Discrete semiconductors: Schottky diodes,
Zenner diodes, TVS, small signal bipolar transistors, high voltage bipolar transistors, matched pair bipolar transistors, small signal JFET s and MOSFETs,
MCT (MOS controlled tyristors), IGBT.
