| SCHOTTKY RECTIFIERS - PRODUCT DESCRIPTION |
|
The primary advantages of schottky rectifier diodes are very low forward voltage drop and switching speed that approach zero time
making them ideal for output stages of switching power supplies. This latter feature has also stimulated their additional use
in very high frequency applications including very low power involving signal and switching diode requirements of less than
100 picoseconds. These require small Schottky devices with low capacitance. Schottky rectifier diodes are suited for switch mode power supplies and high frequency DC to DC converters. This devices are intended for use in low voltage, high frequency inverters, free wheeling and polarity protection applications. Due to the small size of the package this device fits many applications. Semiconix Schottky rectifier diode series are available in very thin nanoDFN package. These products are ideal for surface mount, 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.

| 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 |
|
SMX-nDFN - NanoDFN package is a very thin (10mils) proprietary wafer level chip size package W-CSP technology developed by Semiconix. SMX-nDFN 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 >220°C, clean, etc. SMX-nDFN packages can also be attached with conductive silver epoxy in low temperature applications. The assembly process is also very simple and inexpensive consisting of 3 steps: - transfer a thin conductive epoxy layer onto the bonding pads; -align to substrate and attach; -cure silver epoxy and inspect. SMX-nDFN packages are available in many sizes with landing pads compatible with the industry standard CSP as well as many surface mount packages. |
