APPLICATION NOTE Varicap Diode, Varactor Diode, Variable Capacitance Diode or Tuning Diode is a type of diode which has
a variable capacitance that is a function of the voltage impressed on its terminals. Varactors are operated
reverse-biased so no current flows, but since the thickness of the depletion zone varies with the applied bias voltage,
the capacitance of the diode can be made to vary. Generally, the depletion region thickness is proportional to the
square root of the applied voltage; and capacitance is inversely proportional to the depletion region thickness. Thus,
the capacitance is inversely proportional to the square root of applied voltage. All diodes exhibit this phenomenon to
some degree, but specially made varactor diodes exploit the effect to boost the capacitance and variability range
achieved - most diode fabrication attempts to achieve the opposite. Varactors are principally used as a
voltage-controlled capacitor, rather than as rectifiers. They are commonly used in parametric amplifiers, parametric
oscillators and voltage-controlled oscillators as part of phase-locked loops and frequency synthesizers. Flip Chip
Varactor diode series are available in die form in four different pad compositions: -FC, -GB, -GT and -AN. These
products are ideal for high reliability hybrid circuits, multi chip module applications and surface mount applications.
HIGH RELIABILITY BARE DIE AND SYSTEM IN PACKAGE - SHORT APPLICATION NOTE COB (Chip on Board) and SiP
(System-in-Package) are integrating proven mature products in bare die of mixed technologies i.e. Si, GaAs, GaN, InP,
passive components, etc that cannot be easily implemented in SOC (System-on-Chip) technology. COB and SiP have small
size footprint, high density, shorter design cycle time, easier to redesign and rework, use simpler and less expensive
assembly process. For extreme applications the bare die has to withstand also harsh environmental conditions without
the protection of a package. KGD, Known Good Die concept is no longer satisfactory if the die cannot withstand harsh
environmental conditions and degrades. Standard semiconductor devices supplied by many manufacturers in bare die are
build with exposed aluminum pads that are extremely sensitive to moisture and corrosive components of the atmosphere.
US Microwaves has reengineered industry standard products and now offers known good die for bare die applications with
gold interconnection and well-engineered materials that further enhance the die reliability. US Microwaves also offers
Silicon Printed Circuit Board technology with integrated passive components as a complete high reliability SIP solution
for medical, military and space applications. DISCRETE SEMICONDUCTORS MANUFACTURING PROCESS Discrete semiconductors are
manufactured using US Microwaves in house high reliability semiconductor manufacturing processes. All semiconductor
devices employ precision doping via ion implantation, silicon nitride junction passivation, platinum silicided contacts
and gold interconnect metallization for best performance and reliability. MNOS capacitors, Tantalum Nitride TaN or
Sichrome SiCr thin film resistors are easily integrated with discrete semiconductors on same chip to obtain standard
and custom complex discrete device solutions. All thin film microwave products are manufactured using advanced
semiconductors and thin film technologies including ultra-stable and self passivating Tantalum Nitride resistors, gold
interconnect metallization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability.
Thin film technology is the preferred solution for all applications that require low noise, long term stability and
excellent performance at very high frequencies. US Microwaves employs proprietary thin film technologies for deposition
of a wide range of resistive films with sheet resistance films from 1Ω/sq to 10,000Ω/sq. All US Microwaves products
are available in die form and are ideal for high reliability hybrid and multi chip module applications. All US
Microwaves products are manufactured using GOLD CHIP TECHNOLOGY™ a trade mark of Semiconix Corporation. Maximum

ASSEMBLY PROCESS - SHORT APPLICATION NOTE US Microwaves flip chip components are designed for dry assembly processes as
well as for processes that use adhesives, fluxes etc. Dry assembly process is an assembly process that does not use
additional solders, fluxes or adhesives. Thermosonic wire bonding is a dry assembly process. US Microwaves Flip Chip
-FC series can be also used for thermosonic wire bonding. US Microwaves Gold Bump -GB series are flip chips that are
thermosonically attached to a circuit. US Microwaves Gold Tin -GT series are flip chips with Au/Sn, 80/20 metallized
pads. GT series can be attached to circuits by bringing the die in contact with a substrate which temperature is more
than 280°C. Upon cooling bellow 280C, the die is firmly welded to the substrate. Flux less dry assembly is most
reliable but is also most expensive because of thick gold bumps or expensive Au/Sn process. US Microwaves -FC series is
designed to be used for flip chip assembly with conductive silver epoxy. It is a simple and inexpensive process
consisting of 3 steps: - transfer a thin conductive epoxy layer onto the bonding pads; -align to substrate and attach;
-cure silver epoxy and inspect. Same procedure may be used also with -GB series in certain applications. US Microwaves
Gold/Nickel -AN series is the most efficient wafer level chip size package W-CSP designed for mixed surface mount and
flip chip applications. The assembly process is same as for packaged surface mount components. The process consist of
at least 3 steps; -screen print solder paste on the printed circuit board; -flip chip, align and attach to the tacky
solder paste; -dry paste, reflow at T>220°C, clean, etc. US Microwaves Flip Chip -AN series are available in many
sizes with landing pads compatible with the industry standard CSP as well as surface mount packages. STANDARD PRODUCTS
