| ZENER DIODES - PRODUCT DESCRIPTION |
|
Zener diodes are p-n junction diodes. From the point of view of breakdown mechanism, true Zener diodes are only diodes with reverse breakdown
voltage less than approximately 5.6V. Diodes with breakdown voltage >5.6V are in fact avalanche diodes. Zener diodes are used in simple
shunt voltage regulators circuits, reference voltage, and for ESD protection.
Zener 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.

| 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. Semiconix
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. Semiconix also offers Silicon Printed Circuit Board technology with integrated passive
components as a complete high reliability SIP solution for medical, military and space applications. See AN-SMX-001

| DISCRETE SEMICONDUCTORS MANUFACTURING PROCESS |
|
Discrete semiconductors are manufactured using Semiconix 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.

| SEMICONDUCTOR ASSEMBLY PROCESS - SHORT APPLICATION NOTE |
Semiconix 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. See Application note AN-SMX-000.
