SMV1405-074 Common Cathode Varactor (Tuning) Diode 2pF VARACTOR 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. 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 TECHNOLOGY™ a trade
mark of Semiconix Corporation. Maximum Ratings at TA = 25°C, unless otherwise specified Parameter Symbol Value Unit

backside SEMICONDUCTOR ASSEMBLY PROCESS - 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
