BIPOLAR SILICON TRANSISTORS NPN - PRODUCT DESCRIPTION
Semiconix Semiconductor NPN low power transistors series are designed to be used in a wide variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillators. Semiconix Semiconductor NPN low power transistors series are available as discrete devices or as part of a hybrid integrated circuit (complex devices) packaged in a very small area.
Semiconix Semiconductor transistors series may be used in many applications as hybrid Circuits, automotive, biotechnology, computers, military, medical, MEMS, optoelectronics, space, telecommunications, smart cards, RFID, PDA, laptops and mobile phones.
NPN low power transistors remain the devices that excels in some applications, such as discrete circuit design, due to the very wide selection of NPN low power transistors types available, and because of their high transconductance and output resistance compared to MOSFETs. The NPN low power transistor is also the choice for demanding analog circuits, especially for very-high-frequency applications, such as radio-frequency circuits for wireless systems. Because of the known temperature and current dependence of the forward-biased base-emitter junction voltage, the NPN can be used to measure temperature by subtracting two voltages at two different bias currents in a known ratio. Since base-emitter voltage varies as the log of the base-emitter and collector-emitter currents, NPN low power transistors can also be used to compute logarithms and anti-logarithms.
Semiconix NPN low power transistors series are available in very thin nanoSOT, common surface mount SOT like and through hole TO style packages.
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. 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
SMX-nDFN - NanoDFN and SMX-nSOT - NanoSOT package are very thin (10mils) proprietary wafer level chip size packages W-CSP technology developed by Semiconix.
SMX-nDFN - NanoDFN and SMX-nSOT - NanoSOT are 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 - NanoDFN and SMX-nSOT - NanoSOT 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 - NanoDFN and SMX-nSOT - NanoSOT packages are available in many sizes with landing pads compatible with the industry standard CSP as well as many surface mount packages.
