DIODES - PRODUCT DESCRIPTION AND SHORT 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 Ratings at TA = 25°C, unless otherwise specified Parameter Symbol Value Unit

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
