They allow a current through them to rise to a certain value, and then level off at a specific value. Flip Chip Current Regulating Diodes 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. 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.

Thermosonic wire bonding is a dry assembly process. Semiconix Flip Chip -FC series can be also used for thermosonic wire bonding. Semiconix Gold Bump -GB series are flip chips that are thermosonically attached to a circuit. Semiconix 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. Semiconix -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. Semiconix 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. Semiconix Flip Chip -AN series are available in many sizes with landing pads compatible with the industry standard CSP as well as surface mount packages.
