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. Single
Varactor Diodes BD series are available in die form in two configurations, Top Cathode XXXX-BD or Top Anode XXXXA-BD.
In die form, these products are ideal for high reliability hybrid circuits and multi chip module applications. Common
Cathode or Common Anode Varactor Diodes BD series are available in die form in single configuration: Common Cathode in
TOP ANODE configuration and Common Anode in TOP CATHODE configuration. 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

SHORT APPLICATION NOTE US Microwaves standard bare die components are designed for thermosonic GOLD wire bonding and
AuSi eutectic die attach. For AuSn or AuGe die attach process, Ti/Pt/Au or Ti/Pd/Au are recommended backside
metallization. For soft solder die attach, backside metallization may be any of Ti/Ni/Au, Ti/Pt/Au, Ti/Pd/Au. For
silver filled conductive epoxy die attach, AuSi as well as Ti/Ni/Au, Ti/Pt/Au, Ti/Pd/Au may be used. In general, after
die attach, prior to wire bonding operation an oxygen RF plasma clean operation is recommended. IMPORTANT NOTE:
Aluminum wire should not be used with gold pads due to potential reliability problem known as purple plague. Same it
applies to Aluminum bonding pads with gold wire! In the transition from SnPb solder to lead free and RoHS compliant
packaging and assembly processes the reflow temperature has increased in some cases from 180°C to 220°C. This may
cause an increase of the rate of formation of gold aluminum intermetallic compounds that are brittle and are conducive
to increased contact resistance and or bond failure. STANDARD PRODUCTS ORDERING INFORMATION VERSION SMS P/N WAFFLE
