(Tuning) Diode 330pF 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

Single Varactor (Tuning) Diode 330pF 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
